"Agent Cooper is the finest lawman I've ever known. I've had nothing but respect for him since he arrived in Twin Peaks."―Sheriff Harry S. Truman[src]
Federal Bureau of Investigation Special Agent Dale Bartholomew Cooper is an unconventional investigator who was assigned to investigate the brutal murder of the popular high school student, Laura Palmer in the town of Twin Peaks, Washington. He ended up falling in love with the town and gained a great deal of acceptance within the normally tight-knit community. He displays an array of quirky mannerisms such as giving a 'thumbs up' when satisfied, quoting sage-like sayings, a distinct sense of humor, and a passionate love for the Double R's cherry pie and a "damn fine cup of coffee." One of his most popular habits is keeping a tape-recorded journal with his portable microcassette recorder and addressing all entries to a mysterious woman named "Diane." These entries range from important observations or notes regarding a case to the often energetic, yet superfluous observations of everyday life.
As a boy, Dale lived at 1127 Hillcrest Avenue in Philadelphia, Pennsylvania and attended Germantown Friends School, run by Quakers, though his father told him that if they belonged to a religion, they would not be Quakers, but Unitarians. An asthma sufferer, Dale was often confined to his bed after an attack while his mother rubbed VapoRub on his chest and told him of dreams she had, telling him "we can see things in our dreams that we can't see when we're awake."
On Christmas 1967, Dale was given a Norelco B2000 tape recorder by his parents, with which he began to create audio recordings detailing his life.The first adventure he had with his tape recorder was in early 1968 when he investigated the 24th Street gang, who had stolen a bike belonging to Dale's friend and next-door-neighbor, Bradley Schlurman. The gang ended up stealing his tape recorder, but it was recovered by the police when a gang member was caught stealing a car. Nevertheless, he was unable to return Bradley's bike.
During this time, Bradley's older sister, Marie began to dance in her window just across from Dale's room, causing him to begin to discover sexual feelings. Dale also became a member of the Boy Scouts of America, and Marie helped him earn a knot-tying merit badge by letting him tie her up in her room.
On March 8, 1968, Dale's paternal grandmother was visiting and had a fatal stroke in the kitchen whilst making a pie. His mother had him place his hand on his grandmother's forehead to show him that death was not to be feared.
His next excursion with his tape recorder occurred in April 1968, when he decided to see why the girls are taken to health class every day at the same time. He climbed into an air vent and looked into the classroom from above; inside was a lesson on female anatomy. Dale was caught by the janitor, Mr. Brumley and was forced to hand over his tape of the class. His tape recorder was also banned from school unless he had written permission from a teacher.
On his fourteenth birthday, Dale received a Timex watch from his parents and was told that his brother had moved to Canada to become a lumberjack and would not be seen until all of the trees were cut down. However, he quickly determined that the truth is that Emmet was dodging the draft.
He began to express more of an interest in Marie, but she claimed she could no longer talk to him until he was older. After the assassination of Bobby Kennedy, Marie stood naked in her window, looking toward Dale's room. When Kennedy's body was transported by train through Philadelphia, Marie kissed Dale and tearfully ran away.
The following summer, Dale decided that he was going to become an agent of the Federal Bureau of Investigation and sent a letter to J. Edgar Hoover to tell him of his plan to join the FBI and tell him of his daring scientific expedition to record the girls' sex education class. Hoover responded, praising him and to not be discouraged about being caught. Hoover also gave Dale an invitation to tour the FBI headquarters.
Dale went to the FBI headquarters in Washington, D.C. with his father, where he met Hoover and was given a tour by a special agent and demonstrated his exceptional marksmanship, outscoring the agent.
Marie returned from her family's summer vacation several weeks later. Having become a flower child, she voiced her distaste for Dale's wish to join the FBI, calling him an "establishment pig." She began seeing a boy named Howard, shredding Dale's hopes of her being interested in him. However, when she was taken to the hospital after a drug overdose, Dale visited her, and she offered him sexual favors if he helped her escape, but he declined on the grounds of scout law. She later sent him a letter apologizing for her behavior and saying that she had shaved her head.
After an asthma attack in December 1968, Dale had a dream of a man trying to break into his room while letting out an animalistic roar. He told his mother, who was aware of the man and told Dale to not let the man into his room. He continued to dream of the man throughout the following month while battling an illness, but never let him through the door.
In early 1969, Marie told Dale that she had found Jesus and wished to help him see the light. Dale noted that although he did not like everything about the "new" Marie, her legs were "the most beautiful things" he had ever seen in his life up to that point. On Valentine's Day, she sent him a card that contained a drawing of her holding a baby Jesus. Dale was not sure what to think.
A girl named Anne Sweeny moved into town in 1969 and Cooper became infatuated with her. He blew up her mailbox to relieve his feelings. Anne moved away at the end of the school year.
The night of the Apollo 11 moon landing, Marie confirmed her interest in Dale but then began to pray, much to Dale's disappointment. The landing also had a profound effect on his father, who began to print maps of the moon for his business.
The following day, Dale went to a Boy Scout jamboree and decided to come home on foot, despite the jamboree having been 176 miles from home. During his journey, on July 30, 1969, Dale had his very first cup of coffee in the Post and Beam restaurant on Route 487. Shortly after, he met a couple named Star and April, traveling in a VW bus. He traveled with the couple, who were on their way to Washington, D.C. to chain themselves to the doors of the Pentagon. After parting ways with them, he hitchhiked his way back home.
On November 1, 1969, Dale's mother suffered a dream of the man, who she said almost got in the door. Just two weeks later, she was rushed to the hospital with a brain aneurysm and died the next morning with Dale and his father by her side. She was cremated and her ashes were taken to a small river north of Philadelphia.
In 1970, Dale met April again, as she was student teaching his English class. She had broken up with Star after a fight. April tried to teach Dale how to write poetry, but it was soon apparent that it was not his area of expertise. During the summer, April left for a commune in Colorado.
On May 25, Cooper had a dream of his mother, who reached out and touched his hand. When he awoke, a small gold ring was in his hand. His father told him that the ring belonged to Dale's mother, but he had not seen it since before they were married and it had once belonged to her father.
In July, Cooper and his father went on vacation with the Schlurmans to the Poconos. On the night of Independence Day, Dale and Marie went to the woods and as she began to pleasure him, a rocket landed near them and started a fire. He managed to save her sneakers and he and his father left the next morning.
Just over a week later, Dale received news that Marie had drowned at Promised Land Lake, having hit her head while diving into the water. She was buried in a silver coffin.
In September, Dale had finished high school and his whereabouts for the following three years are unknown. However, as indicated by letters he sent to his father, he was in an area with water and snakes and needed to travel by ship at one point. Upon returning, he told Bradley Schlurman that his trip was "damn good."
In the summer of 1973, Dale got a job digging holes with a man named Jim, whose home burned up one night and his body was not found. However, Cooper saw the shadow of a man in a nearby alley, where laughter also occurred.
In the fall, he enrolled at Haverford College, and his father gave him a new tape recorder. He became attracted to a girl named Andy from the nearby Bryn Mawr college. The two had a sexual encounter but were caught by students at their respective schools. Subsequently, he found out that she would be leaving for Holland with her husband.
In November of 1973, he pursued a man who he believed to be a predator of sorts and ended up finding a young woman who had been beaten and stabbed to death.
Dale returned home for Christmas and began to experiment how long he could function without sleep. During this time, he mused that he never liked the name Dale and wished he was an Apache named Ten Sticks, and also began to express doubt that Lee Harvey Oswald did not act alone in the assassination of John F. Kennedy and that his death was not unrelated to the death of Marilyn Monroe. He managed to not sleep for over a full day before drifting off to sleep, experiencing vivid dreams.
Andy returned from Holland in January, without her husband. She and Dale spent a night in a motel room for a "study on the limitations of the mind and body." Andy returned to Holland just weeks later, after her husband was injured.
In March of 1974, Dale took an internship at the county hospital to study mental patients. During this time, he connected with a patient named Betty. However, just over a day later, she held a knife to an orderly's throat and was shot by police. When she was wheeled out, Cooper recalled her saying, "I'm free," and she later died from her wounds.
The following summer, Dale's father married a woman named Charlotte and she became pregnant. However, she subsequently left him for a photographer, who was biologically responsible for the child.
The tapes documenting Cooper's life between September 11, 1974 and June 9, 1975 were destroyed in a fire that also destroyed some of his clothing.
Dale met a young woman named Lena in July 1975, who shared his love of coffee and had taken a vow of celibacy after her mother seduced her former boyfriend. They visited her family in Hershey, where Lena attempted to burn down the family home to come to terms with her mother. Following their trip, Lena underwent psychiatric evaluation and by December had married her high school sweetheart.
In early 1976, Dale's father became bankrupt and moved into the apartment above his print shop. Dale also completed his studies at Haverford. His whereabouts over the next year are unknown, but he did note in February 1977 that "Evil does have a face."
Cooper was accepted into the FBI in the summer of 1977 and completed his training by December. He was given a new tape recorder by his father and was assigned a secretary named Diane, who he described as a "cross between a saint and a cabaret singer." He began to address his tapes -- both personal and work-related -- to her.
In January of 1978, he was given his first assignment: investigating the kidnapping of an eight-year-old girl named Chris Roe, who he found chained to a tree, having been kidnapped by a bookseller.
During a triple homicide investigation the following month, he met forensics expert Special Agent Albert Rosenfield, whom he described as angry. He commented that whoever committed the murders could not have been entirely human.
In April, he met Agent Earle again, who had been following Cooper's progress, as he remembered him from the job fair.
On May 1, 1978, Cooper took the life of a bank robber who had killed a hostage. He was given a leave of absence to come to terms with the killing. During this time, Cooper began playing chess with Windom Earle and met his wife, Caroline, who wished that the death would not affect Cooper's life "the way it did Windom's" when he first took a life.
Upon his return to work, Cooper was given desk duty, during which time he had a dream of a legless man saying that "It" is behind him and is "sure to kill." After being released from desk work, he was assigned as Windom's partner.
Cooper was put on the investigation of a man who had been murdered, whose face was destroyed and his hands removed. He suspected it to have been the result of organized crime. Earle also began to act strangely and disappeared.
Another body was found under the same circumstances, and Dale began to bond with Caroline, bringing her comfort during Windom's absence. After the hands belonging to this body were found, Cooper was introduced to deputy director of the Criminal Investigation Division, Gordon Cole, who oversaw the case.
Caroline received a call from Windom on August 3, during which he only said: "I'm sinking." The next day, Earle showed up at his office and collapsed. Cooper visited him at the hospital to try and discern where he was during his disappearance. Earle only gave elusive answers, speaking of an "abyss." Windom later claimed to have forgotten what occurred during his absence and no arrests were ever made in the case, despite four months of investigation.
Sometime around 1985, Cooper vacationed on an island in the Caribbean, where he met an old man who had taught Earle how to play chess. However, when Cooper tried to learn from him, the man refused, saying, "There is death in your face." Following this, the old man disappeared. Dale tried to find the man, but found him dead, hanging by a rope. Cooper then fled the island, feeling that something bad had happened in Pittsburgh.
He arrived in Pittsburgh to find that Caroline had been kidnapped by three men as the Earles ate dinner. She was found in April after being arrested for prostitution in lower Manhattan, suffering from a heroin addiction.
Caroline was moved to a safe house following an attempt on her life. Cooper put her under hypnosis and learned of her horrifying experiences, though she was unable to identify the persons responsible. Earle decided not to stay in the safe house, and thus began an affair between Dale and Caroline. However, only days later, the lovers were stabbed by Windom. Caroline's injuries proved to be fatal. Following the murder of Caroline, Windom was institutionalized and Dale took full responsibility.
Months after the murder, Cooper went on a road trip with his father to San Francisco. However, his father stayed in Reno, Nevada after meeting a woman named Shamrock and marrying her. In San Francisco, he was assigned to the case of a murdered 19-year-old male prostitute. In pursuit of a serial killer, Cooper followed a blue Dodge Dart that nearly ran over a prostitute, but this perpetrator was not the killer. The killer was soon identified as a man named Bush, who Cooper ambushed at his home and brought into custody.
Sometime around 1986, Cooper had a dream involving the plight of the Tibetan people and revealed to him the deductive technique of the Tibetan method. Deeply moved by what he saw in this dream, he formed the basis of his unconventional methods of investigation.
In the summer of 1987, Cooper worked with the DEA Agent Dennis Bryson on a sting operation in Tijuana. However, things went sour when Bryson's cover was blown and he was taken as a hostage. Cooper managed to rescue him, and the newspapers stated the incident to have been caused by an argument over the Book of Job.
Two months later, Cooper worked one more case with the DEA task force, which concerned a dentist trafficking cocaine through his practice. The mission was a success; however, Dale discovered in the process that he had six cavities.
In early 1988, Cooper received a tape from Windom Earle, taunting him.
Murder of Teresa BanksEdit
On February 15, 1988, Cooper revealed to Cole of the portents of the strange dream he had about the Tibetan people two years prior, and that it made him worried about the current date.
Later, he played a memory game with Diane: he had to figure out what changes Diane had made to the room in his absence. After considering it for a while, he realized that Diane had moved the clock on the wall twelve inches to the left.
In the meantime, Special Agent Chester Desmond disappeared while investigating a bizarre murder case of a teenage prostitute named Teresa Banks, whose body was found wrapped in plastic in Deer Meadow, Oregon. Cooper picked up the case but was unable to find any evidence which could lead to the discovery of what happened to Desmond or the murder victim.
He later had a somewhat awkward and brief meeting with Sam Stanley, who had assisted Desmond in his investigation. They discussed the Deer Meadows investigation and Stanley's encounter with the missing Agent Desmond. Like Desmond, Cooper refused to divulge the meaning of Lil the Dancer's blue rose to Sam. Cooper learned about Teresa Banks' missing ring and a mysterious letter under her fingernail during this meeting.
Roughly a year later, Cooper told Albert Rosenfield in the Philadelphia FBI offices of how he sensed Banks' killer would strike again soon, and that his victim would be a young woman, who had blonde hair, was sexually active, using drugs, and was crying out for help. Rosenfield was quick to dismiss Cooper's notion.
After being missing for two years, Special Agent Phillip Jeffries re-appeared behind Cooper in the hallway outside Gordon Cole's office, which Cooper did not notice, as he was checking the security camera (in which he saw himself still standing in the hallway as Jeffries walked straight past him). Cooper followed him into Cole's office and bore witness to Jeffries' fragmented outburst. He briefly exited the room to check the hallway, as a result missing Jeffries' disappearance.
Murder of Laura PalmerEdit
Because of its similarities to the Teresa Banks murder, Cooper was assigned to investigate. He arrived in the town at 11:30 AM whilst addressing a tape to Diane, commenting on all of the trees he had seen, as well as the weather, his car's gas level, and his lunch. He noted that he would meet with Sheriff Harry S. Truman at the hospital to see Ronette Pulaski, a girl who had been reported missing and was subsequently found.
He arrived at the hospital and met Sheriff Truman and while respectful of the sheriff, he made sure that Truman was aware that the FBI had taken control of the case and expected his full cooperation. After Truman confirmed his awareness, Cooper excitedly asked what kind of trees they had around the town, which Truman confirmed to be Douglas firs. Following this, Cooper asked for the coroner's report on Laura, but the autopsy had yet to be done. Truman took him to Ronette, who had been raped. No connection was yet known between her and Laura. Cooper tried to question her, but she was unresponsive. He requested to examine her fingers but did not find what he was looking for. As he did this, Ronette began saying "don't go there."
Cooper and Truman later found themselves in an elevator with a one-armed man, who exited when they saw Doctor Lawrence Jacoby, who tried to run to them, but the elevator closed and continued to descend. Jacoby then showed up on the next floor where they stop and he introduced himself to Cooper. The psychiatrist asked to join them in the morgue, but they did not allow it. Jacoby also said that Laura's parents did not know that she had been seeing him.
They went to the morgue, where the lights were flickering. He examined the body and found a small piece of paper under the nail on her left ring finger. Printed on the paper was the letter 'R.'
At the sheriff's station, Cooper went over the evidence retrieved from the Palmer home, including a videotape and Laura's diary, which he planned to view with Laura's boyfriend, Bobby Briggs. Since they had no key, Cooper broke the lock on Laura's diary and noted the last entry that said "nervous about meeting J tonight." Inside, he also found a page where taped was a plastic bag containing a safety deposit box key and a white residue he suspected to be cocaine.
Bobby was brought in for questioning, Cooper's first question being whether he killed Laura, which was denied. Cooper then said that she had been at Bobby's house studying until about 9:30, which Bobby confirmed, as well as that she had driven herself home. He also brought up the fact that they had a fight, which angered Bobby even more, much to Cooper's amusement. He then played the videotape for Bobby of Laura and her best friend, Donna Hayward, which Bobby denied filming. He also brought up the fact that Laura was cheating on him, which he believed to be the subject of the fight. He then asked if Bobby has ever used cocaine with Laura, which he denied. Cooper then typed into a calculator, "HE DID NOT DO IT," and showed it to Harry. He brought up a person with the initial 'J' as the person who filmed the video and asked if Bobby knows who it is, which Bobby denied.
Donna was then brought in for questioning, but she insisted that the person who filmed the video was a female hiker that she did not know the name of. Cooper then released Donna. Lucy Moran, the receptionist at the sheriff's station then came in to tell him that she overheard Bobby and his friend Mike discussing a biker with the initial 'J,' but Cooper had already figured this out, as he noticed a bike reflected in Laura's eye on the videotape.
Dale then went to the scene of the murder with Truman, which happened to be a train car, where he found blood, a hammer, and bloody rag, a dirt pile with half a heart necklace, and a note reading in blood "FIRE WALK WITH ME."
Cooper then went with Truman to open Laura's safety deposit box, where in the office, a taxidermy deer head had fallen. They opened the box and found a copy of Flesh World and over $10,000. Inside the magazine, they found a marked page, where a photo of Ronette was printed.
Cooper later gathered the town for a conference to announce the FBI's takeover of the Laura Palmer case. Truman filled him in on the identities of several people who attended. Mayor Dwayne Milford called the meeting to order and Cooper takes over. He announced to the citizens that Laura's murder has striking similarities to the murder of Teresa Banks a year prior and believes them to be killed by the same person, possibly a citizen of Twin Peaks. He suggested a curfew for those under the ages of 18, as the crimes occurred at night.
In the evening, he sat with Sheriff Truman at a stakeout at the Roadhouse when Lucy patched through a call from Doctor Will Hayward, who reported his daughter, Donna being absent. The sheriff put out an all-points bulletin. Cooper then whittles a whistle, saying, "that's what you do in towns where a yellow light still means slow down, not speed up." They then saw Mike and Bobby arrive, followed by Donna. He suggested to Harry to call in backup and gave him a thumbs-up.
Having seen Donna leave with a biker named Joey Paulson, they pursue. Truman proposed that he could be 'J," but Cooper believed he is simply taking her elsewhere to perhaps meet with 'J." They followed at a "discreet distance" until they lost sight of them. Cooper breathed in the smell of trees until they heard motorcycle engines and head toward them. They gave chase when they saw James Hurley and Donna pass and stopped them with no trouble. When Donna insisted that James did not do anything, Cooper said that she was probably right.
Cooper awoke the next morning at 6:18 and addressed a tape to Diane about the exceptional conditions of his room at the Great Northern Hotel and two things that trouble him: what really went on between Marilyn Monroe and the Kennedys and who really pulled the trigger on JFK. He then had breakfast at the hotel, where he highly approved of the coffee and met Audrey Horne, who told him about her brother, Johnny, who had been tutored by Laura Palmer prior to her death.
Cooper went to the sheriff's station, where Doctor Hayward emotionally delivered the post-mortem report on Laura Palmer to him and Truman. They then questioned James Hurley on his connection to the murder, specifically, the secret relationship he had with Laura and their activities together on the night of the crime.
Cooper later met Ed Hurley and confirmed with him that his nephew James had been cleared as a suspect in the murder. He then received a call from Albert Rosenfield, who was coming up to Twin Peaks to assist in the investigation. He released Mike and Bobby, who had been arrested for brawling at the Roadhouse, but first warned them not to touch James.
He and Truman then headed to the Packard Sawmill, where he met Josie Packard -- who had been tutored in English by Laura Palmer -- and asked her about Laura's actions during the last time they met. Cooper then deduced that Truman and Josie are romantically involved, much to Harry's embarrassment.
The two lawmen later went to the Double R Diner, where Cooper tried a slice of their famed cherry pie. There, he met the owner, Norma Jennings and asked about Laura Palmer's activities with the Meals on Wheels program.
Cooper then went to his room at the Great Northern with his flute and received a phone call from Deputy Hawk, who informed him of Ronette's condition and what he learned from her parents: that she recently quit her job at the perfume counter at Horne's Department Store. He also told him about the One-Armed Man's presence at the intensive care unit, so Cooper told him to keep watch on Ronette. There was then a knock on the door, but nobody was there when Cooper answered it. However, they leave a note reading "Jack with One Eye."
The next morning, he gathered Sheriff Truman, Deputy Hawk, Deputy Andy, and Lucy to eliminate suspects by throwing a stone at a bottle placed 60 feet and 6 inches away, which he called the "Tibetan method," an idea he got from his dream a year prior. This narrowed down his suspicion to Dr. Lawrence Jacoby and Leo Johnson. Truman also informed him that the "Jack with One Eye" may refer to the casino up north called One Eyed Jack's.
Cooper and Truman then examined a bloody rag found by Hawk just as Albert Rosenfield arrived with his team. Albert immediately displayed his impatience and distaste with the Twin Peaks Sheriff's Department, which Cooper found to be entertaining, though Truman was not amused in the least.
Later that night, Cooper went to bed and drifted off to sleep. He began dreaming and had visions of a red room, a small man, the One-Armed Man (who identified himself as MIKE), and of a mysterious man called BOB. He sees himself 25 years older in a red room continued and he saw a woman resembling Laura Palmer, who kissed him and whispered the name of her killer in his ear. Cooper suddenly woke up and called Harry to tell him knew who killed Laura.
As he strolled down the hall of the Great Northern the next morning at 7:15 AM, Cooper addressed a tape to Diane, telling her that he planned to go to the sheriff's office after breakfast, then to Laura Palmer's funeral. He encountered Audrey as he sat down for breakfast and confirmed through her handwriting that she wrote the "Jack with One Eye" note. She confirmed with him that she was referring to the casino and that "men go there." She also told him that Laura worked the perfume counter at Horne's Department Store, the same place as Ronette.
Truman and Lucy then showed up, curious of his statement that he knew who killed Laura Palmer. Cooper explained his dream as a code to solve the crime, and about MIKE and BOB, though he did not remember the name Laura whispered into his ear.
Cooper and Truman then went to the morgue, where a fight had broken out between Rosenfield and Doc Hayward. The Sheriff became fed up with Albert and punched him. Coop then separated the two and ordered that the body of Laura Palmer be released to the family for the funeral.
After being fascinated by a group of ducks near the Johnson home, Cooper was filled in on Leo by Truman. He questioned Leo about Laura and knew his criminal record, though Leo claimed that he was with Shelly on the night of the murder.
They went to the sheriff's office, where Albert waited with his post-mortem report on Laura Palmer, the details on her being bound consistent with the words spoken by the dream of Laura he had the night before. After Truman left, Albert requested Cooper to sign a report on the scuffle between he and the Sheriff, but Cooper refused on the grounds that the incident was caused by Rosenfield. Albert left and Cooper addressed a tape to Diane at 12:27 PM, requesting her to look into his pension plan options regarding outside real estate, expressing his desire to stay in Twin Peaks after the investigation.
Cooper later attended the funeral, observing the citizens, especially Bobby and James, the latter showing up late. The two young men charged at each other, but the fight was quickly broken up as Leland Palmer dove on top of the casket.
Later that evening Cooper arrived at the Double R Diner, joining Ed, Hawk, and Truman, easily sensing that Ed was in love with Norma, much like he did with Truman and Josie before. Over a piece of huckleberry pie, he discussed the Sheriff's Department's operation to stop drug trafficking between Twin Peaks and Canada. Truman informed him of an evil that haunts Twin Peaks, and the secret society that defends the town against it: the Bookhouse Boys. They took him to their meeting place, the Bookhouse, where James and Joey Paulson were waiting with Bernard Renault and they questioned him about the drug operation and his brother Jacques Renault's actions.
Later in the evening, Cooper went to the cemetery, where he saw Dr. Jacoby visiting Laura's grave. He noted that the doctor had not been at the funeral and questioned him, to which Jacoby explained his feeling of guilt over Laura's death.
He then joined Hawk at the Great Northern and they discussed their beliefs in souls and the presence of Laura's. They drank to her and witnessed Leland having a nervous breakdown on the dance floor. The lawmen then comforted him and took him home.
The next day, in the conference room at the sheriff's station, Dale questioned Dr. Jacoby on his involvement with Laura Palmer, though the psychiatrist was not very compliant. After he left, there was a call from Cole, who gave further information on Albert's results and troubles with Truman. Andy then came in and showed him the sketch of a man Laura's mother had a vision of, which happened to match the appearance of BOB in Cooper's dream.
After Hawk tracked down the One-Armed Man, Philip Gerard, to a motel, Truman and Cooper came and find him. They showed him the sketch of BOB, though he said he had never seen him before, but he did know a Bob Lydecker. He also said he is a shoe salesman and that he did have a tattoo on his lost arm, but it said "Mom."
Cooper and Truman then visited the Lydecker Veterinary Clinic, but the receptionist said that the sketch was not of Bob Lydecker, though the special agent did not give up on this lead due to Lydecker's connection with the One-Armed Man. Determining that the bird that attacked Laura Palmer was a client at the clinic, they confiscated the clinic's files.
Due to Andy dropping his gun at the motel, Cooper gathered the deputies for target practice, Hawk's aim being exceptional, though Andy was left with much room for improvement. The men then talked about women as the FBI agent and the Sheriff practiced.
Andy, Truman, and Cooper looked through the clinic files to find the bird that attacked Laura. Cole called and informed them that the bird was a parrot or myna bird. The results on a plastic object in Laura's stomach determined it to be part of a poker chip with the letter 'J' on it. Andy then found a record for a myna bird named Waldo, owned by Jacques Renault.
Cooper, Hawk, and Truman then made their way to Renault's apartment. However, he was not home, though someone was seen running away from the apartment. They found a bloody shirt belonging to Leo Johnson.
Cooper is awakened the next morning at 4:28 AM, due to loud Icelandic businessmen on his floor. He recorded a tape, requesting Diane to send him ear plugs. Audrey then tried to join him for breakfast, but he was running late, so he left with his coffee.
He then went to join the investigation at Jacques's apartment, though Jacques had not been seen in two days. Doc Hayward informed him that the blood on the shirt is not Laura's, which then prompted Cooper to believe that the blood belonged to Jacques, somehow knowing his blood type, which Doctor Hayward confirmed moments later after making a phone call. Dale then found a copy of Flesh World hidden on the ceiling, in which he found letters to Ronette, a Polaroid photo of a man in drag and a picture of Leo's truck printed in the magazine.
The P.O. box listed on the letters was found by Hawk to belong to Jacques and that he also sent letters to Laura, which Cooper then connected to the red drapes he saw in his dream and a photo of a cabin in Jacques's apartment.
Hawk then lead Cooper, Truman, and Hayward to a cabin that they suspected to be the one in the photo. On the way, they stop at the Log Lady's cabin, where she had been waiting for them. She said that her log saw something significant and Cooper asked the log what it saw. The Log Lady then answered for it, saying it witnessed the murder of Laura Palmer and that there were three men present. The group continued through the woods and found the cabin Cooper saw in the photo. Inside was a record player, which was playing "Into the Night." Waldo was also found in the cabin along with a camera, blood, and the rest of the poker chip that was partially in Laura's stomach.
Cooper walked back to his room at the end of the day as the Icelandic men became loud once again. He saw that his door was ajar, so he drew his gun and entered, telling whoever was inside to turn on the light. The intruder did so, revealing that they were Audrey, in Coop's bed and upset, requesting him to not make her leave.
Dale sat down on his bed, gently telling Audrey that he could become romantically involved with her, but that she needed a friend. He then left to get food so they can talk to each other.
The next morning, he entered the Sheriff's Department with his flute and made his way to the conference room where Doctor Hayward and Sheriff Truman were with Waldo, trying to get him to talk. Hawk then brought Cooper forensics results indicating that Laura, Ronette, and Leo were all in Jacques's cabin. Dale left his voice-activated tape recorder near the birdcage in case Waldo talked before they headed out.
Cooper later went with Truman to the Double R Diner, where they saw Hank Jennings, Norma's husband, freshly released from prison. Truman then wanted to leave, but Coop insisted they stay and treat themselves to cups of black coffee.
Later, Coop walked through the Great Northern in a tuxedo, ready to go to One Eyed Jack's to investigate Jacques with Ed. Truman told him that Josie suspected that Catherine and Benjamin wished to burn down the sawmill. Cooper agreed to investigate it with him.
Dale and Ed then prepared to leave, getting into their disguises and wireless microphones. A gunshot rang out in the conference room and they went in to find Waldo dead. Cooper found a recording of the bird saying "Laura, Laura, don't go there," "Hurting me, hurting me," "Stop it," and "Leo, no!"
They went to One Eyed Jack's, where they meet Blackie O'Reilly, identifying themselves as Barney and Fred. She pointed them to the casino, where Coop played blackjack and Jacques came to deal the cards.
Cooper played blackjack and wins as he rejected a working girl's advances. He gave Jacques the chip found in his apartment and identified himself as a friend of Leo's before offering to buy him a cocktail. They talked about the drug operation and Jacques's actions on the night Laura Palmer died, along with Waldo and Leo's involvement. Cooper arranged for Jacques to meet him in two hours so that the Sheriff's Department could ambush him and he noted to Hawk his suspicion of Jacques involvement in Laura's murder.
After being shot by Andy, Jacques was taken to the hospital, where Cooper questioned him on his involvement with Laura Palmer and Leo Johnson on the night of the murder, though he said he knew nothing about the train car, where the murder occurred. Cooper and Truman then checked up on Dr. Jacoby, who was also in the hospital. Jacoby had been brought there after having a heart attack following an attack by an unknown assailant.
They then went to the sheriff's office, where Lucy informed them about a call from Leo Johnson, during which she could hear a bell from Easter Park. James then came in needing to talk to Harry, but Cooper had him investigate the call instead and talked to James, who gives him a tape of Laura's, pointing suspicion to someone with a red Corvette. Harry then brought in a bag of cocaine found in James' gas tank and Cooper questioned him about it.
Cooper returned to the Great Northern at 4:37 AM and addressed a tape to Diane about the events that had occurred over the course of his very busy day. On the way inside of his room, he found a note on the floor, addressed to "My special agent" and the phone rang. On the other end was silence and there was a knock on the door. He opened the door and was shot in the abdomen three times.
Cooper laid on the floor, bleeding as Andy's voice was heard through the phone. A senile room service waiter came in with a glass of warm milk. Cooper asked him to put it on the table and call a doctor, but the confused waiter hung up the phone, Cooper believing he made the call. The waiter had him sign the bill for the milk and thanked him before saying he had heard about him, giving him a thumbs-up and a wink before leaving and repeating the thumbs-up, this time Cooper giving one in return. The same thing happened once more and a Giant appeared to the special agent, saying he will tell him three things and to think of him as a friend. The Giant told him "there's a man in a smiling bag," "the owls are not what they seem," and "without chemicals, he points." However, he could say what they mean. The Giant took Cooper's ring -- the same one that once belonged to his mother -- and said he will return it if the things he said come true. He then said "Leo locked inside a hungry horse. There's a clue at Leo's house," before saying Cooper will require medical attention and disappearing.
Cooper began addressing to Diane, hoping his recorder had the voice-activation function on. He told her about his current condition, thankful he was wearing his bulletproof vest but was hit directly once due to his folding up the vest while chasing a wood tick. He noticed his ring was gone and began telling Diane about his regrets and things he wished he could have done. Truman, Hawk, and Andy then arrived at the hotel room.
He awoke at the hospital with Truman, Lucy, and Doc Hayward standing above him and told them what happened. Hayward showed him a bullet that hit him and even managed to kill the tick. Lucy then told him about the current conditions of Leo Johnson's shooting, Jacques' death, and the mill fire.
Against Hayward's orders, Cooper got up and got dressed. While walking around the hospital, he saw Jacques' body bag being rolled out and commented, "is that bag smiling?"
The lawmen then went to the Johnson home to investigate the shooting of Leo. Cooper deduced exactly what happened, uncertain that Shelly was the one that pulled the trigger. Hawk then found a copy of Flesh World along ith Leo's duster, which smelled of gasoline. Rosenfield then arrived and Andy tried to warn Truman, stepping on a loose board and being hit in the face. The board revealed a hidden pair of boots and a stash of cocaine.
Rosenfield examined Cooper's current condition after the shooting and reprimanded him for moving his vest to chase the tick. Andy then came in and told Cooper he has a solution for the "Leo locked inside a hungry horse" riddle, informing him that Leo was in a jail in Hungry Horse, Montana on February 9, 1988, the night Teresa Banks was murdered.
In the interview room where Truman is questioning James, who informed them that the missing half of Laura's necklace was found in a coconut in Jacoby's office, surprising Cooper, who believed James to have had it.
Cooper then had Andy and Lucy look through an archive of Flesh World to find a photo of Teresa Banks and left them on their own as he addressed a tape to Diane.
The special agent and Truman went back to the hospital to see Jacoby, to ask how he came into the possession of half of Laura's necklace, who tells them that the night after the murder, he followed Leo but then saw James and Donna bury the necklace. After they left, he dug it up and took it as a keepsake. He then told them about Laura's double life and that proposed that she had reached the point where she wanted to die and allowed herself to be killed. The lawmen then questioned him about what he knows about the death of Jacques Renault, noting a peculiar smell, but that it was not a typical post-mortem smell, but something like scorched engine oil.
They then walked through the hospital with Rosenfield and spot Bobby Briggs, questioning his presence, then they ran into Ed, who told them Nadine was in a coma after an attempted suicide. Truman and Albert left Cooper and Ed alone, who talked about the unhappy relationship between the Hurleys and their sudden marriage and honeymoon. He revealed that while they were hunting on their honeymoon, Ed accidentally shot Nadine's eye out with a buckshot. James was then released to Ed as Cooper walked away and saw Jacques' body bag drying out, which looked like it is smiling.
The Sheriff's Department later in the conference room, with Cooper delivering his thoughts on Laura's actions the night she was murdered, including her activities with Leo, Jacques, and an unknown third man.
At 11:55 PM, a tired Cooper addressed a tape to Diane in bed about his tiredness and his experience the night before of seeing the Giant, who soon appeared to him again after Dale signed off. Th Giant told him that he forgot to tell him something, that "one person saw the third man. Three have seen him, yes, but not his body. One only known to you." He also told him that Cooper forgot something and he disappears.
The following morning, Dale ate breakfast with Albert, telling him about Tibet, though the latter much preferred to focus on work, especially the status of Ronette (who had awakened from her coma) and the whereabouts of "BOB." Albert revealed the autopsy of Jacques, finding that he was not strangled. Cooper then noted that his ring as gone, proof to himself that the Giant was real. Much to Cooper's shock, Rosenfield then revealed to him that Windom Earle was unaccounted for.
Cooper and Truman then visited Ronette in the hospital, though she was unable to speak but otherwise conscious. They showed her the sketch of Leo, asking if he was the one who attacked her, but she indicated that he was not. Cooper then showed her the sketch of "BOB," causing her to go into a panic and mention a train.
The two went to Truman's office, where Hank Jennings was waiting. After Hank left, Truman told Cooper a little bit about their history before Lucy interrupted, saying that Benjamin Horne was calling. Truman passed along Ben's message to Cooper that Audrey had gone missing.
Later in the evening, Cooper addressed a tape to Diane about his worries over the whereabouts of both Earle and Audrey. There was then a knock at the door from Major Garland Briggs, who delivered to him a message from a top secret source about signals received from space, and that on the night Cooper was shot, one of the waves read 'THE OWLS ARE NOT WHAT THEY SEEM' and one the next morning said 'COOPER.'
At night, Cooper was woken up by a call from Audrey, who said she saw him in his tuxedo and that she planned to come home, but suddenly, Audrey's end of the line was hung up.
The next morning, Cooper arrived with Albert to Ronette's room. Ronette had just been sedated, and he extracted the letter 'B' from under her fingernail. He then told Harry and Albert about the dream that he had about the Giant and the signs he was told. 
Cooper later made a diagram proposing that Mrs. Palmer, Maddy, Ronette, and himself were linked to the long-haired man called "BOB." Albert then announced his forensic findings before insulting Sheriff Truman and getting in a heated confrontation with him.
Cooper then let James leave, telling him he knew the cocaine in his gas tank was planted and did not want to see him arrested again. He then checked on Lucy, who was tasked with finding as many words as she could that used the letters found under the fingernails.
Leland Palmer then showed up at the Sheriff's Department and told the lawmen that he knew the man in the sketch and said that he had met him near his grandfather's summer home near Pearl Lakes when he was a boy and the man lived in a white house with the name "Robertson." He also said that the man used to flick matches at him, saying "you wanna play with fire, little boy?"
Cooper and Truman then sat down with Shelly to get a statement from her concerning Leo, but she was reluctant, not wanting to say anything against him. The special agent passive-aggressively let her go and supposed that the reason she would not talk was that she was after insurance money from her husband's invalid state.
He then went to Benjamin Horne and asked him about whether he knew anything about Audrey's disappearance.
The FBI man and the sheriff then took a break and they discussed Josie's impending return the next day, Truman requesting to see her first, in private. Hawk then came in with his report over the white house in Pearl Lakes. He was then told by Truman that the one-armed man had been at the station and had to go to the bathroom to take his medication, which reminded Cooper of his dream in which the man knew "BOB."
The lawmen then visited Dr. Jacoby, who was with his wife, Eolani, and Cooper hypnotized him. Jacoby revealed that he heard tape ripping and the sounds of Jacques dying and that he knew the face of the killer.
They then went to the Palmer home and arrested Leland for the murder of Jacques.
Cooper and Truman took Leland back to the station to interrogate him. He waived his right to an attorney and confirmed that he went to the hospital to search for the man who killed Laura and tearfully confessed that he murdered Jacques out of grief.
Later, Truman told Cooper that the judge and the prosecutor were on the way into town. He also read off the report from Hawk about the white house, that nobody named Robertson lived near the Palmers. Dale then noticed Andy's boots, who said they were bought from Philip Gerard, the One-Armed Man. They were the same brand as the boots that belonged to Leo.
Later, Benjamin Horne showed to Cooper a video of Audrey in captivity and asked him to personally deliver $125,000 in ransom money.
Cooper later walked in on an argument with Andy and Lucy, but he excused the former in order to ask Lucy what had been clearly frustrating her. She told him about things she has noticed about Andy that she did not like and found the opposite in a man named Dick Tremayne. However, she tearfully said that she did not know what she wanted to do and walked away as Truman showed up. Cooper then informs him that he needed the services of the best Bookhouse Boy, but did not say for what purpose.
Judge Clinton Sternwood later arrived at the Sheriff's Department and was introduced to Cooper. Truman stated that they should find that they have a lot in common. Leland then appeared before the judge, who expressed his condolences. However, he decided to wait for the prosecutor to make a ruling. They all then left Cooper and Truman, the latter confirming that the plan was set for the night with the Bookhouse Boy.
The Bookhouse Boy then met Cooper at the Roadhouse, revealed to be Truman himself, wearing street clothes rather than his Sheriff's uniform.
Cooper awoke at 6:42 AM the next morning and addressed a tape to Diane while beginning his morning with a headstand, which made him spot a note from Audrey under the bed and determined this to be what the Giant said he had forgotten. The note pointed to One Eyed Jack's.
He arrived at the station as Lucy left to visit her sister and he told Harry that he knows where Audrey is.
Leland's hearing was then held in the Roadhouse, where it was decided that he be released on bail, but must remain in Twin Peaks until his trial. Following this, the hearing concerning Leo was held, where the extent of his brain damage was revealed. However, the judge did not come to a decision on whether Leo will face trial or not, and Cooper told him he did not believe Johnson is guilty, though he is confident that the right man will be found. The judge then told them that he saw Leo as unfit to stand trial and had Truman deliver this news to Shelly as he told Dale his thoughts of the woods in Twin Peaks.
Cooper studied a layout of One Eyed Jack's when Truman showed up, followed by Hawk, who bought in drugs found in the One-Armed Man's hotel room. After Hawk left, the other two discussed their plan to rescue Audrey.
Later that night, the two approached One Eyed Jack's and Cooper noticed a strange owl as Truman knocked out a security guard. They entered the building, searching for the room where Audrey was held. They split up when Truman looked into a room occupied by Jean Renault and Blackie O'Reilly. Cooper ran into Blackie's sister, Nancy, who he restrained and had her lead him to Audrey. When the woman attempted to stab him, he incapacitated her and took Audrey. He then met up with Truman and they started to make their way out but were held up by a man with a gun, who was hit with a blade seconds later, revealed to have been thrown by Hawk.
Cooper delivered Audrey to safety with Truman and Hawk. He determined that her captors had injected her with heroin as she began speaking and showing distress.
He and Harry later met in the latter's office, where Harry told Cooper about Jean Renault, who killed Blackie at One Eyed Jack's. Cooper then expressed that this is not the first time that his duties have endangered someone he cares about.
In the evening, Ben Horne met the special agent in the Great Northern's dining hall. Dale told him about Renault's killing of Blackie and the condition of Audrey, who was then recovering from a near-lethal amount of heroin.
Cooper then brought Horne to his daughter and they took her home, against Audrey's wishes for Cooper alone to take her.
Gordon Cole then arrived in Twin Peaks and stated to Cooper his admiration for the Sheriff's Department and that he reminded him of "a small Mexican chihuahua." Cole warned him that he may be in over his head. Truman then entered and Gordon delivers a letter to Cooper of a chess deal, presumably from Windom Earle.
Cooper, Gordon, Hawk, and Truman later speak with Philip Gerard, who wished to have his medication, and without it, he seemed to completely switch personalities and identified himself as "MIKE" and that he was an inhabiting spirit. He said that "BOB" is a parasitic spirit feeds on fear and pleasure, and that the two were once partners and that he now wishes to stop "BOB," who had been in the presence of Twin Peaks for nearly 40 years and was in the Great Northern.
The following morning, the lawmen joined "MIKE" for coffee, Truman announcing that they were ready to begin their duties for the day. Gordon then left for Oregon. Cooper, Truman, and Andy then went with "MIKE" to the Great Northern to find the host of "BOB." When Ben Horne entered the room, "MIKE" suffered a seizure.
Subsequently, they went to the home of Harold Smith, who had a secret diary belonging to Laura in his possession. However, he had hanged himself and the diary was partially destroyed. Cooper pieced together some of the pages back at the station, noting the presence of a "BOB" being abusive to her over a large period of her life, and said that she will one day "tell the world about Ben Horne." Audrey then came in and told him that her father had a physical relationship with Laura at One Eyed Jack's, of which he is the owner. Cooper told her to not mention this news to anyone else and then told Harry to get a warrant for Horne's arrest.
Cooper, Truman, Hawk, and Andy went to Horne's office while he was in a meeting with a Mr. Tojamura and told him he was wanted for questioning in the murder of Laura Palmer, but he was resistant and tried to leave, causing the deputies to apprehend him and take him into custody.
Back at the Sheriff's Department, the Log Lady showed up, telling Cooper and Harry that "there are owls in the Roadhouse" and confirmed the former's suspicion that "something is happening."
The three traveled to the Roadhouse and sat at a table as the blonde singer performed onstage. Cooper amusingly observed the Log Lady eating a lot of peanuts. Minutes later, he seemed to enter a dream and the musicians onstage disappeared and were replaced by the Giant, who said "it is happening again... it is happening again," before he disappeared and the band returned. The elderly waiter came over to the table and said, "I'm so sorry," and walked away, leaving Cooper deep in thought.
The next day, Cooper and Truman went to the Great Northern as the former addressed a tape to Diane, giving his thoughts on the One-Armed Man. They encountered a dancing Leland in the Timber Room and they informed him of the arrest of Ben Horne. Cooper requested Leland to inform him if he were to remember anything strange about Horne's behavior and then he left with the Sheriff, commenting that he was not sure whether everything is fine.
After Doc Hayward received a blood sample from the Horne, the lawmen spoke to the suspect in the interrogation room, with Jerry Horne present. Cooper asked him if he knows anything about the secret diary of Laura Palmer and revealed to him that the lawmen know about One Eyed Jack's.
When the One-Armed Man went missing, Cooper and Truman began to search for him, but they encountered Leland, who was swerving on the road in his convertible and apparently on his way to try out his new golf irons. He told them that he remembered that on the night Laura was murdered, Horne mentioned a "dairy," which Cooper assumed to actually be "diary." Leland then offered to show Cooper his new clubs, but the agent left, as Lucy informed Truman that Gerard had been located.
The One-Armed Man was brought to the interview room with Ben Horne and said that "Bob" is not present, but had been nearby. In spite of this, Truman charged Horne with the murder of Laura Palmer, and Cooper voiced his disagreement.
Cooper addressed a tape to Diane at 11:05 that night from his hotel room, noting the empty sky and the events of the day, stating his belief that they had yet to find the killer. Audrey showed up at his door and asked what he thought about whether her father was guilty of the crime or not. He then received a call. Another body wrapped in plastic had been found: Maddy Ferguson, Laura's nearly-identical cousin.
The following day, Rosenfield stated that his findings of Maddy's murder pointed to the same person who killed Laura. Cooper requested 24 hours to find the culprit.
Donna Hayward then informed him about an elderly woman named Mrs. Tremond and her grandson who spoke to her the same words that appeared on Harold Smith's suicide note. She took him to the Tremond home, however, a different woman with no connection to the old woman Donna had met answered. She gave them an envelope from Harold, which happened to be a page from Laura's diary - entries from February 22 and 23. In the first entry, Laura described exactly Cooper's dream, except from her point of view. In the second, she described that it would be the night that she dies.
Cooper went to "MIKE's" bedside for his help. "MIKE" spoke of a ring, the one taken from Cooper by the Giant, who could help him find "Bob." When he left the room, he saw the elderly waiter, speaking some of the same words he spoke the night of the shooting, in addition to the words "getting warmer now."
Agent Cooper then made his way to Horne's office, where the Sheriff's Department searched for evidence, which Truman determined to still point the finger at Horne. Rosenfield then presented Ben's blood test.
Ben, Leland, Leo, and Bobby were all then rounded up into the Roadhouse with Agent Cooper, Ed, Albert, and the Sheriff's Department. Cooper stated that he believed among them was the killer, based on the use of his methods, but said that he must then rely on what he calls "magic." Major Briggs then showed up with the elderly waiter, who gave Cooper a pack of gum and said to Leland, "that gum you like is going to come back in style." Cooper then remembered the words Laura spoke to him in his dream: "my father killed me." The Giant appeared and gave back the ring. The special agent asked for Ben Horne to be brought to the Sheriff's Department, with Leland as his attorney. He followed them out but paused to give the old waiter a thumbs-up.
Upon arriving at the station, Cooper told Leland that Ben would be charged and he whispered in Harry's ear. The group approached the interrogation room and as Ben was nearly escorted inside, Leland was shoved in. The lawmen subsequently entered the room, handcuffing a giggling and howling Leland, who confirmed that he killed Laura and Maddy.
Cooper told Truman all of the clues pointing toward "BOB" in the body of Leland. These clues included that Ben's blood test was negative, the man in the dream danced (which Leland did following the murder), Leland's hair turning gray (the color of "BOB's" hair). Leland began to chant a poem, followed by the sprinkler system being triggered. Leland ran head-first into the interrogation room door and in his dying words came to the realization that he had killed his daughter and asked for forgiveness, and spoke of when "BOB" took control of his actions. He also confessed to the murder of Teresa Banks. As Leland died, Cooper recited the last rights from the Tibetan Book of the Dead. Leland then saw a vision of Laura, an apparent sign of forgiveness from her, and he died.
The following morning, Agent Cooper, Albert, and Truman met Major Briggs and they discussed the mysterious nature of "BOB." Albert supposes that "BOB" was the embodiment of evil and Truman questioned the current whereabouts of this being.
Suspension from the FBIEdit
Three days later, Cooper sat with Sarah Palmer and Doc Hayward as they prepared for Leland's funeral. He comforted Sarah, assuring her that it was not truly Leland who committed the heinous acts BOB was responsible for and that her husband died at peace with Laura. He then offered to drive her to the funeral.
After the funeral, Cooper gathered with the town at the Hayward household, where a reception was held. He made it known that he was considering using his available vacation time to spend more time in Twin Peaks. He then witnessed a scuffle between Mayor Dwayne Milford and his brother Dougie, and Pete Martell explained their sibling rivalry that had taken place over the years.
Later, he folded his laundry in his room as Audrey came in. He said to her that he was going fishing with Major Briggs, but then will leave the town afterward. He once again explained his convictions that he could not be in a romantic relationship with her and told her about Caroline dying under his watch.
Cooper went to the Sheriff's Department to say his goodbyes before going on the fishing trip. Harry gave him a Green Butt Skunk fishing lure and a Bookhouse Boy patch, effectively making him an honorary member. However, as he went to leave, Special Agent Roger Hardy arrived with RCMP Officer Preston King, informing Cooper that he had been suspended from the FBI. Hardy told him that the suspension was in relation to the rescue of Audrey Horne and Cooper's suspected motivations behind it.
Hardy questioned Agent Cooper about his visits to One Eyed Jack's and the deaths that occurred during Audrey's rescue. He was informed that his actions compromised a sting operation to stop Jean Renault's drug operation and that they believed Cooper may be responsible for stolen cocaine. He was then asked to hand over his gun and badge.
Later, he roasted marshmallows with Major Briggs and discussed his actions as well as the subject of BOB and darkness. Briggs mentioned something called the White Lodge, but before speaking any further on the subject, Cooper excused himself to urinate. Suddenly, a bright light appeared and Major Briggs was nowhere to be found.
The next day, Cooper and Truman spoke with Betty Briggs about her husband's disappearance and that it may have been related to what was classified information. When she left, the Special Agent said that the disappearance was not work-related. Gordon then called, informing Cooper that he had his back in the investigation and informed him that Dennis Bryson was being sent by the DEA. He then met with Hardy in the conference room, stating that he had no defense, as he believed his actions to be right.
He then spoke with Truman and Hawk, asking about the White Lodge, which took Hawk's interest. He described the Lodge as being a place where spirits reside. He also spoke of the Black Lodge, the shadow being of the White Lodge. Dennis Bryson then arrived, who Cooper is surprised to see wearing feminine clothes. Dennis then asked to be called Denise and filled them in on the allegations against Cooper. After Denise left, Hawk commented, "That's a good color for him."
Later, Cooper sorted through his mail, one envelope being from Windom Earle, containing a chess move and a cassette tape, taunting him. In the evening, he received a phone call from Denise, whom he agreed to meet with at the wedding reception for Dougie Milford and Lana Budding. Agent Bryson informed him that a trace of cocaine was found in his car, feeding the suspicion that Cooper was being framed. Cooper then had a dance with Audrey.
A realtor, Irene Littlehorse, took him to the farm, telling him that there is some kind of strange, spiritual connection to the farm and not many people stay. The door was found to be unlocked when they arrived, and Cooper believed there had been a meeting at the house. He then found baby laxative in the sink drain and cocaine on a chair.
Back at the station, Cooper met Colonel C. Reilly of the Air Force, who was heading the investigation of Briggs' disappearance. He asked if he had seen any owls, which Cooper confirmed. Reilly revealed that the messages concerning Cooper supposedly having come from deep space actually came from the woods and that the Briggs disappearance was beyond an issue of national security.
He later addressed a tape to Diane concerning a newspaper, in which a chess move from Windom Earle was printed. He also caught her up on his status with real estate in the town and the continuing mysteries it held. There was a knock at his door from Audrey, who brought him pictures of Jean Renault and his dealings with Hank, King, and Ernie Niles. Denise subsequently arrived. Audrey gave him a kiss and left, Cooper subsequently showing Denise the photos.
Denise and Cooper then questioned Niles in his involvement with Renault and the drug trafficking. He insisted that he did it all against his will and they told him that a major drug supplier would arrive from Seattle and that he was to set up a meeting at Dead Dog Farm.
The next morning, Briggs had been found alive and came to the station to discuss his absence. Briggs noted that he had seen an image of a giant owl and when questioned on the nature of his work, he said it is classified. He then brought up Project Blue Book, which still existed in an unofficial capacity and that they were searching for a place called the White Lodge. Air Force personnel then escorted Briggs out as Cooper observed a photograph of three triangles that had appeared behind the Major's ear.
Dale then went to Denise and Ernie, the latter having been convinced to call Renault and make the buy. Cooper then who to Lucy, who he assigned to check personal ads in newspapers for more messages from Earle.
Cooper, Hawk, and Truman then prepared Ernie for the operation and the sheriff made the agent into an honorary deputy of the Twin Peaks Sheriff's Department, so he could participate directly in the sting operation within the law. Denise then entered as Dennis.
Cooper watched the operation from afar with Hawk and Sheriff Truman, but Ernie's wire malfunctioned due to his excessive sweat, causing Renault and King to take Ernie and Denise as hostages. Dale gave himself up in exchange for them.
The Sheriff's Department and the state police soon surrounded Dead Dog Farm. Jean told Cooper that he held him responsible for the deaths of both of his brothers since everything in Twin Peaks seemed to change ever since the FBI Agent arrived in town. Denise then arrived in a Double R Diner waitress outfit, hiding a gun on her leg, which Cooper took and shot Jean Renault dead as Agent Bryson subdued King.
Cooper and Truman went back to the Sheriff's Department, which had its power off, due to an explosion, which Lucy says to have been from a bomb. Cooper then went to Truman's office, finding a dead man gagged in front of a chessboard.
Return of Windom EarleEdit
Cooper examined the man's body with Dr. Hayward, finding a black pawn in his mouth. Cooper then correctly determined that they will find a stab wound. He and Truman then found a lodgepole pine needle as Hawk came in, having found one person's set of footprints to and from the station. Cooper knows this murder to be the work of Windom Earle.
Cooper was later informed that he had been cleared of all criminal charges, but he was still suspended, awaiting word from Gordon. Harry allowed him to take charge of the current murder case. Hawk then came in and informed them that Hank was in the hospital after being "hit by a bus" and that Leo was now mobile, having attacked Shelly before escaping into the woods.
Dale later stood over a chessboard in Harry's office, elaborating on his relationship with Windom, his affair with Caroline, and her subsequent murder.
Briggs then arrived at the Sheriff's Department, dehydrated. The Major told them that he believed he was in the White Lodge during his absence and that trouble will come. He then left and Andy came in to show them to Dr. Jacoby, who explained his findings concerning Lana Milford and her condition that caused the death of her new husband. Mayor Milford then arrived with a shotgun, believing Lana to be responsible for his brother's death. The deputies, Truman, and Cooper managed to get the mayor to surrender and left in alone in the conference room with Lana as they waited. After they waited, they entered to find the Mayor with kiss marks on his face and announcing that the two of them had decided to adopt a child.
The next day, Cooper and Truman questioned Bobby and Shelly over the situation with Leo and the night that the mill burned down. Bobby noted a connection between Hank and Leo. Truman also informed Shelly that he would post deputies around the perimeter of the Johnson home.
Albert then returned with information about Windom Earle, on orders from Gordon, for he was "worried about Coop." He presented locations where Earle had sent packages containing articles of clothing: a white veil, a garter, white slippers, a pearl necklace, and a wedding dress, all belonging to Caroline.
Cooper and Truman then confronted Josie about the death of Jonathan. Coop went to get some coffee and talked to Pete, who was struggling with a load of dry cleaning and handed it all to Cooper so he could answer the phone. The special agent used this opportunity to take some fibers off of some of Josie's clothing. Albert compared them to fibers found outside of Cooper's room and confirmed that Josie was the one who shot him and that she was also most likely responsible for Jonathan's death.
Cooper went to Truman's office, where Harry informed him that they had identified Earle's victim as a vagrant named Erik Powell. Dale noted that Powell was Caroline's maiden name and believed this to not be a coincidence. They then went to the Double R Diner where Cooper and Doc Hayward both lost against Pete at a game of chess. Cooper decided to bring him on board to help with the Windom Earle case.
He later looked at a photo of Caroline and he went back to his room, where a white mask waited on his pillow and a tape played from Windom to Dale.
The next morning, Coop listened to Earle's tape with Truman, who swore that he would protect him. They call over Pete Martell.
Albert showed him the findings that proved Josie to be the one who shot him and killed Jonathan, but Cooper delayed the arrest, saying that he would talk to her to see if she would confess. However, she insisted that she had nothing to do with the murder. He commanded her to be at the station house at 9:00 or else he would come find her himself.
Pete discussed chess moves with Cooper and Truman, trying to figure out the next move to make against Earle. Albert arrived, informing Cooper privately that the powder found on Josie's gloves matched the gun. Truman overheard this and left the sheriff's station.
Cooper later sat in his room and received a call from Catherine Martell, who told him to go to Thomas Eckhardt's suite, where there was some sort of commotion taking place, culminating in a gunshot. Dale burst into the room, where Eckhardt stood, having been shot, and he then died. Josie was on the bed, pointing a gun at Cooper and he questioned her on Jonathan and his own shooting. Harry then showed up and demanded her to put down the gun. She pointed it at her head and collapsed, then Harry rushed to her and said that she was dead. Cooper then saw a vision of BOB, who tauntingly asked "what happened to Josie?" then he disappeared and the little man from his dream appeared dancing before disappearing.
Harry became devastated by Josie's death and Cooper unofficially took his place in his stead. Cooper noted that Hayward's autopsy on Josie found that her body only weighed 65 pounds.
Cooper then went to Harry at the Bookhouse and told him Josie's criminal history, that she was a wanted felon. Truman was angered by this and shouted at Cooper to leave.
Cooper went to Pete, who had several chess boards set up, trying to play every stalemate game ever played, with the least amount of pieces lost. The Log Lady then arrived, escorted by Major Briggs. Briggs spoke of the marking behind his ear and the Log Lady showed a mark of two mountains on the back of her knee.
Cooper then went to the Double R Diner, where he met Norma's sister, Annie Blackburn and was immediately smitten. He noticed a scar on her wrist as she poured a cup of coffee that he highly approves of. Hawk then came in to retrieve him to go see Harry.
Harry was now angry and drunk, having thrown around all of the furniture in the Bookhouse. Cooper tried talking him into handing over his gun and that his life was not over now that Josie's was. As Truman broke down into tears, the two friends embraced. Truman later fell asleep and Cooper commanded Hawk to keep an eye on him.
The next day, Harry returned to work after Thomas Eckhardt's assistant, Jones, had tried to kill Harry. They had the woman in custody but she only wanted to speak with the South African consulate. As Cooper gave him a recipe for a hangover cure, Truman became sick.
Doctor Hayward then came to inform them that Earle had been at his house and delivered a chess move. Gordon Cole then arrived with a portion of Earle's dossier for Dale. They learned that Earle was part of Project Blue Book in 1965. Gordon then reinstated Cooper into the FBI before they headed out for breakfast.
They arrived at the Double R Diner and Gordon immediately (and loudly) became smitten with Shelly. Cooper drew on a napkin and looks outside at some birds while Harry came over from the restroom. Annie then came over to serve coffee. Cooper began telling Annie a joke, which was interrupted and Harry completely picked up on Cooper's attraction to Annie, much like Dale noticed Harry and Josie's attraction weeks earlier. Cooper then finished the joke, which Annie found quite funny. She also recognized the drawing Cooper had made as looking like a design at Owl Cave.
Cooper, Truman, Hawk, and Andy then explored Owl Cave, searching for the symbol. Owls swooped overhead after they find it and Andy accidentally struck the symbol, causing it to partially open and reveal a petroglyph.
Later at the Great Northern, Dale began addressing a tape to Diane, describing the day's events but stops when he saw Annie at the bar and went to speak with her, continuing to be fascinated by her.
The lawmen went back to Owl Cave, noting that someone had been there before them. Hawk noticed the same tracks he saw at the power station: Windom Earle. Cooper told Andy to make a large-scale drawing of the glyph.
Dale arrived at the Double R Diner and asked Annie for coffee and donuts before inviting her to go on a nature study with him later that afternoon. Dale then heard Shelly Johnson reciting a poem that was given to her, Donna, and Audrey by Earle.
He took the poem to Harry and explained it to him as a poem he had once given to Caroline. Hawk then brought Donna's portion of the poem, and Cooper asked him to bring Leo's arrest report. He then went to the conference room, where Briggs waited with Andy. He then requested Briggs' help to discover the extent of Earle's involvement with Project Blue Book, but while Briggs was reluctant, he agreed to do what had been requested. Cooper then looked over Leo's file, comparing the handwriting with the poem, which he determined to have been transcribed by Johnson.
Later, Coop sat in a canoe with Annie, enjoying nature and talking. The subject of one of her ex-boyfriends came up but proved to be a tough subject for her. Cooper then told her that he understands the kind of pain she has faced. They then shared a kiss and went back to shore, hand in hand.
Later in the evening, Cooper sat by a fireside at the Great Northern with a glass of milk and was joined by John Justice Wheeler. The two discussed love and everything it brings as well as their respective romantic situations.
At the park, a wooden box suspected to be a bomb was found in the gazebo. He opened the box to reveal a large black pawn with a dead man inside. Attached was a note that read: "next time it will be someone you know."
As the pawn was removed, a young man told the law enforcement about the victim -- named Rusty Tomasky -- and what had happened to him prior to his murder. Cooper noted that this move from Earle was without warning.
Cooper and Truman later met with Briggs, who had been going over Project Blue Book files and Earle's involvement with the project. Earle had been removed when he started to become obsessive and violent. They viewed a tape of Earle discussing an evil place called the Black Lodge. Dale supposed that the real reason his old partner came to Twin Peaks for the Lodge and not purely to terrorize him.
Cooper called a meeting with Shelly, Audrey, and Donna, asking them if they had any strange encounters prior to receiving their parts of the poems. Shelly also confirmed that the handwriting was Leo's and the special agent told the girls safety precautions to take, as they are in danger.
He later observed the glyph with Harry and Andy, trying to interpret it. As Andy went to check on the status of Briggs' impending arrival, Cooper looked out the window, thinking about Annie and talked about his feelings for her with Harry. Suddenly, his hand started shaking uncontrollably, but he managed to stop it.
He went to the Double R where he talked with Annie as she served him coffee. They discussed their respective thoughts about each other and then he offered to take her dancing before they share a kiss and accidentally knock over a plate.
He met her that evening at the Roadhouse, where she reluctantly decided to get up and dance with him, as she did not know how. He began to teach her and they shared another kiss, discussing perhaps more than that. However, they were interrupted by Mayor Milford trying to make an announcement with much microphone feedback. Cooper then saw the Giant, saying "No," and seemingly trying to warn him.
The next day, Cooper and Truman observed the glyph with Andy again and discussed Windom Earle as well as thoughts about the death of Josie and his vision of BOB. He said that BOB may be attracted to fear and has his origins in the Black Lodge.
He later addressed a tape to Diane after meditating, updating her on the situation with the glyph and Windom Earle. He also brought up Annie to her, who then showed up at his door. She requested his input on her speech for the Miss Twin Peaks Contest. After discussing trees and forests as a metaphor for Annie's life, they became intimate.
Subsequently, he went to the sheriff's station where Briggs had been brought in a strange state of mind. The Major answered his questions incoherently, so Cooper decided to keep him in their care. He also told Harry more of his thoughts on the Black Lodge, and the nature of its door and that it requires them to be in a precise place at a precise time.
Cooper noticed that alignment of certain planets have something to do with when the door is open. Briggs then said "fear and love open the doors," Dale believing this to mean that fear opens the Black Lodge and love opens the White Lodge. Briggs also spoke of a queen, and Cooper related this to a chess move by Earle and that this must be whoever would win the crown of Miss Twin Peaks. Andy accidentally knocked over a bonsai plant in the conference room and Harry noticed that it had been bugged by Windom Earle the whole time.
Dale and Harry arrived at the Miss Twin Peaks pageant as Lana Budding Milford began her performance, capturing the attention of every man in attendance. The pageant went on and Cooper found particular resonance with Audrey's speech, declaring that when something one cares about is in danger, one must fight for it, or lose it. As expected, he also listened closely to Annie's speech just prior to the vote for the winner.
The winner of Miss Twin Peaks was announced as Annie, which stunned Cooper, knowing that this meant something to Earle. Suddenly, the lights went out and some turned back on as strobes while smoke bombs went off. Cooper saw Windom Earle dressed as the Log Lady, but a smoke bomb went off in front of him. He searched for Annie as the lights turned back on and she was nowhere to be seen. Andy came to him and announced that he believed the glyph to be a map.
Back at the station, Cooper and Hawk observed the map as Harry entered, saying he had put out an all-points-bulletin for Earle, who was nowhere to be found. Dale noticed in the map the Giant, the little man, and a connection to "fire walk with me." Pete then came in saying the Log Lady stole his truck, but Cooper insisted that she did not and that she would arrive soon. Truman then noticed twelve sycamore trees and knew Glastonbury Grove to have this attribute. The Log Lady then arrived with oil. She told them that her husband brought it to her before he died, saying it was the opening to a gateway. They connect this to Jacoby's earlier statement about "scorched engine oil." Hawk then brought in Ronette Pulaski and she recognizes the smell of the oil from the night Laura was killed.
Cooper went with Truman to Glastonbury Grove, where Pete's truck had been abandoned. He insisted that he must go alone. He headed into the grove, where owls sat in the trees. He spotted footprints outside the apparent gateway, where a red curtain appeared and he went inside.
Once inside, he heard a man singing a song and saw a Venus de Milo statue at the end of what seemed to be a hallway. He entered a room, where the little man danced over to his chair and the light flickered as the man sang in a spotlight.
He sat in the red room from his dream with the little man, who called it the waiting room, offered him coffee, and said some of his friends are here. Laura came and sat down, greeting him and saying "I'll see you again in 25 years" and she disappeared. The senile waiter appeared in her place and served him a cup of coffee. He was then replaced by the Giant, who went and sat down, saying "one and the same" and disappearing. Cooper reached for his coffee, but it turned into a solid form when he tried to drink it, then back to liquid when he tried to pour it, then to a syrup-like state. The little man said "fire walk with me" and the lights began to flicker as Dale heard a scream. He entered the hallway again and went into a room identical to the waiting room. He went back into the hallway and through the entrance he had come from, back to the waiting room, where the little man told him "wrong way" and he went back to the identical room, where the little man appeared laughing, saying there is another friend. Maddy Ferguson appeared, saying "watch out for my cousin" and disappeared.
Cooper left the room and to another one, this being empty until a doppelganger of the little man and Laura appeared, the latter screaming as the light flickered again and Cooper saw a vision of Earle. He ran to another empty room and began to bleed. He followed a trail of his own blood to a room where he saw Caroline and himself. Caroline turned into Annie and disappeared, the light flickering again. He went to another room where he saw Annie again, who sais she saw the face of the man who killed her - her husband. She turned into Caroline, then back to Annie, then a screaming Laura, and then Windom Earle. Annie appeared near them and disappeared. Earle offered to let Annie live in exchange for Cooper's soul, which he accepted. Windom stabbed him, but he then saw BOB grappling Earle, telling him to be quiet, saying that he was wrong, and could not ask for Cooper's soul. BOB took Windom Earle's soul and laughed as Cooper left the room.
He walked through the hallway, where he encountered Leland Palmer's doppelganger, who insisted that he did not kill anybody, then saw his own doppelganger who began to chase him. Cooper's doppelganger escaped the Black Lodge while he remained trapped.
At one point while experiencing a strange dream involving the Black Lodge and its residents, in the non-linear realm, Laura encountered Cooper at a point after he had become trapped there. Cooper implored her not to take "the ring", a mysterious object that gives its wearer a sort of connection to the Black Lodge. This displayed that the Black Lodge does not exist on the same plane of time as everything else.
In the Red Room, sometime after he warned Laura in her dream not to take the ring, he noticed that it was no longer on the table shown to him by the little man. He asked the man where it was and he replied, "someone else has it now." Cooper realized with horror that "someone else" is Annie.
Following her death, Laura's spirit appeared in the Red Room and looked up at Cooper, whose hand rested on her shoulder and he smiled at her. Shortly thereafter, Laura's angel appeared before them both.
25 Years LaterEdit
25 years later, Cooper sat across from a man who resembled the Giant and pointed his attention to the sounds of a phonograph. The man said "It is in our house now," and "It all cannot be said aloud now." The man then told Cooper to remember "430" and "Richard and Linda. Two birds with one stone." He told Cooper that he "is far away," and Cooper disappeared.
Later in the Red Room, MIKE asked Cooper "is it future or is it past?" and said that someone was there. Laura Palmer came and spoke to Cooper, telling him he could "go out now," and asked if he recognized her. He asked her if she was Laura Palmer and she gave an identical answer to the one she gave in the dream he had many years ago: "I feel like I know her, but sometimes my arms bend back." Cooper then asked if she was Laura Palmer, which she confirmed, and that she was both dead and living. She then removed her face, which revealed a bright light, then placed it back. Cooper then asked her when he could leave, and she walked over and kissed him before whispering in his ear, much like the dream from long ago. Suddenly, Laura screamed and a force pulled her out of the room. The red drapes blew back, revealing a pale horse and darkness. MIKE appeared to Cooper again and asked the same question as before and lead him out of the room, showing him to an electric tree with a fleshy mass that the little man -- or, the arm -- had evolved into. The arm asked Cooper if he remembered his doppelganger, and explained that it must be returned in order for Cooper to be allowed to leave.
The arm said "253. Time and time again," and repeatedly said BOB's name before telling Cooper to go. He followed MIKE out of the room and soon found himself in a room with Leland Palmer, who told him to find Laura. Cooper exited the room and the Lodge began to distort. He went back out to the hallway and pulled back drapes to see his doppelganger driving. The Lodge began to shake, with the chevron floor shifting. The arm's doppelganger said "Non-exist-ent!" and Cooper was dropped to the floor to a glass box in New York City. He was transported out of the box and through darkness.
In 2016, a dossier compiled by Major Briggs was found, containing many documents concerning the town of Twin Peaks, and Cole assigned Special Agent Tamara Preston to research it. Among the documents was limited information on Agent Cooper.
His favorite book was noted to be The Official Report of the President's Commission on the Assassination of President John F. Kennedy by The Warren Commission Report, despite Cooper's skepticism on the Commission's findings.
Included in the dossier was The Andrew Packard Case manuscript, retrieved from the Bookhouse and written by Cooper. Agent Preston humorously identified him due to his frequent references in the manuscript to the pie and coffee at the Double R Diner.
Cooper was considered by Major Briggs to be the only natural successor to his role as archivist, however, Briggs was left discomforted for unspecified reasons when meeting with Cooper's doppelganger (presumably believing him to be the Cooper trapped in the Lodge) the day after Cooper returned from the Black Lodge and continued his investigation alone.
According to Agent Preston, at an unspecified time following the Laura Palmer investigation, Cooper's doppelganger left Twin Peaks.
Dale maintained a healthy relationship with his father well into his adulthood, and it was he who inspired the 13-year-old Dale to begin transcribing tapes. Cooper's father also completely supported his decision to join the FBI.
Dale had a good relationship with his mother, who taught him that death was not something to be feared. She also instilled in him to trust dreams. Her death deeply affected Dale, and when he had a dream through which she gave him a ring she used to wear, he began to wear it on his pinky finger for many years.
Cooper's relationship with his brother prior to the latter leaving for college is unclear. However, is was presumably a good one since Dale wished he was able to come to their mother's funeral. However, after Emmet caught wind of Dale joining the FBI, he sent him a letter calling him a "tool of the establishment" and said that he would "rot in hell." Despite this, Dale was glad to hear from him.
Dale seemed to have a good relationship with his uncle, and, years down the road, he put the gambling tips he was taught by him to good use.
Twin Peaks Sheriff's DepartmentEdit
Much like how he relates to the town itself, Cooper gained an instant rapport with many of the townspeople on arrival to Twin Peaks — most particularly Sheriff Harry S. Truman and his deputies, Tommy "Hawk" Hill and Andy Brennan.
Harry S. TrumanEdit
While Truman was initially skeptical of Cooper's unconventional investigative methods and otherworldly ideas, he was most often willing to accept Cooper's judgment (even referring to Cooper as "the finest lawman I have ever known" to agents investigating Cooper's alleged drug-running to Canada). Over time, a deep bond emerged between the two, as displayed in various scenes: when Truman assists Cooper in rescuing Audrey Horne from One Eyed Jack's, Truman deputizing Cooper following Cooper's suspension from the Bureau, and Truman waiting patiently for two days at Glastonbury Grove for Cooper to emerge from the Black Lodge.
Cooper had much respect for Hawk and his essential skill for the town's lawmen. Upon his originally-planned departure from Twin Peaks, Cooper said that if he ever became lost, he hoped Hawk would be the one who found him.
Cooper formed a great respect in Andy and helped him whenever needed, particularly when it came to his marksmanship skill. He told Andy that he admired the deputy's bravery and his large heart.
Federal Bureau of InvestigationEdit
Cooper seems to be very close with his superior, Gordon Cole, the two sharing the quirk of often giving a "thumbs-up" sign. When Cooper was suspended from the FBI, Cole expressed his support for him. When Windom Earle came to Twin Peaks, Cole sent Albert Rosenfield to help, as Cole was "worried about Coop."
Cooper's strongest relationship outside of the townspeople was that of his friendship with his colleague, Agent Albert Rosenfield. Though he had strong respect and admiration for Rosenfield's medical skills and was seemingly undaunted by Rosenfield's sarcastic manner, he had little tolerance or patience for Rosenfield's treatment of the town's citizens — most particularly his animosity towards Sheriff Truman (which notably thawed over time).
Cooper's next-door-neighbor Marie was his first romantic interest, following an incident where he saw her in her underwear through her window. Their relationship confused Dale, as she would seem to go back and forth in having an interest in him, and kissed him while she grieved over the death of Bobby Kennedy. Following a drug overdose during a flower child stage, she became a born-again Christian and the two later had a sexual encounter, which was interrupted by a rocket.
Andy was a girl from Bryn Mawr College whom Cooper met while a student at Haverford. After the two had a sexual encounter in the woods, she revealed to him that she was married to a man named Tim, with whom she was to go on an exchange trip to Holland. After returning without her husband, Andy and Dale had a "study on the limitations of the mind and body" inside a hotel room. However, their affair was cut short when Tim was injured and she decided to return to him.
Dale became sexually-frustrated during his time with Lena Fraser, made more serious by her vow to celibacy that was in place until she came to terms with her mother, due to her mother sleeping with a former boyfriend of hers. During a trip to her home with Dale, Lena set the house on fire and on the way back, she and Dale had a sexual encounter in the car, which caused them to hurtle toward a group of cattle. Their relationship was cut off when Lena went to a psychiatric hospital and she later married her high school sweetheart.
Prior to his activity in the town of Twin Peaks, Cooper's strongest romantic relationship was his affair with Caroline Earle, the wife of his former partner, Windom Earle. Caroline had been under Cooper and Earle's protection for witnessing a federal crime Earle committed when he lost his mind, but on one night when Cooper's guard was down, Caroline was murdered by Windom. Caroline's death and his failure to protect her continued to haunt Cooper on his arrival to Twin Peaks, referring to a "broken heart" when discussing women with Truman and his deputies. He also related a version of the story of Caroline to the teenage Audrey Horne.
On arrival to Twin Peaks, Cooper became quickly aware that 18-year-old Audrey Horne, the daughter of local businessman Benjamin Horne, harbored a crush on him. The attraction appeared to be mutual, as Cooper was clearly drawn to Audrey — but he was quick to rebuff her advances when Audrey turned up in his hotel bed. Cooper explained she was too young, but he did genuinely want to be her friend. However, following her disappearance orchestrated by Jean Renault, Cooper privately confessed to Diane that in Audrey's absence all he could think of was her smile. Following her rescue, there remained a close and affectionate friendship with the two, most notably when Audrey arrived at his hotel room for comfort following her father's arrest and her sad farewell when she believed Cooper was leaving Twin Peaks for good. Audrey later gave Cooper a surprising kiss on the cheek when she discovered evidence that cleared him of drug charges, and they later slow-danced at the Milford wedding.
Following his reinstatement to the FBI, Cooper met Annie Blackburn, the sister of Norma Jennings, whom he instantly fell in love with. Annie was established as being a kindred spirit, experiencing the world with curiosity and wonder. Much like Cooper's pain over Caroline Earle, Annie also nursed a broken heart from someone in her past, which was implied to have resulted in a suicide attempt, and affected her decision to later attend a convent. Cooper helped her to prepare for participation in the Miss Twin Peaks Contest and they slept together. However, during the contest, she was kidnapped by Windom Earle and taken to the Black Lodge to use her 'fear' to open the gateway.
Highly intelligent, determined, and perceptive, Agent Cooper is a capable investigator. He lacks skepticism, in direct contrast with fellow agent Albert Rosenfield, and trusts in his dreams to solve cases, in addition to employing unconventional techniques. Despite being in charge of the Laura Palmer investigation, he treats his fellow lawmen as equals and shows a deep concern for their well-being. Cooper also maintains his own quirks, including a love for coffee and cherry pie and a fascination with nature.
- This section covers only the alternate ending presented in the International Pilot.
Cooper begins breathing heavily in his sleep until he receives a phone call from a man who claims to know who killed Teresa Banks and of the "stitches with the red thread." He says he is at the hospital and hangs up. Cooper sits up and receives a phone call from Lucy, who says that Sarah Palmer saw Laura's killer, so Sheriff Truman and Deputy Hawk are on their way to the Palmer home to get a sketch. Cooper tells her to have Harry get the sketch and go to the hospital. He addresses a tape to Diane at 2:24 AM to tell her of the phone calls he just received.
He meets Sheriff Truman at the hospital, where the one-armed man from the elevator waits in the shadows of the room where Laura's body was examined. The man identifies himself as "MIKE" and tells them that he lived above a convenience store with a man named "BOB." Cooper brings up MIKE's activity at the hospital earlier, and MIKE says he was looking for BOB. He also says that he had a tattoo on his arm, but cut the arm off when he saw the face of God. Sheriff Truman shows a sketch of a long-haired man to MIKE, who identifies it as BOB and says he is in the basement.
Cooper and Truman enter the basement, where BOB welcomes them to the "killer's lair." They approach him and he asks if MIKE is with them, wishing to "sing with him again." Harry asks BOB what the letters under the victims' fingernails were going to spell and he answers "Robert." BOB promises he will kill again and MIKE appears with a gun, shooting BOB dead. MIKE is overcome by pain and collapses to the ground. Cooper looks at the candles BOB had set up and says "make a wish" before they go out.
Twenty-five years later, Cooper sits in a room with red drapes, a little man, and Laura Palmer. The little man tells him "that gum you like is going to come back in style." Cooper looks at Laura and asks if that is who she is. Laura responds that she feels like she knows her, "but sometimes [her] arms bend back." The little man says she is filled with secrets and that the birds "sing a pretty song" where they are from. The man begins dancing and Laura comes over to Cooper and kisses him before whispering in his ear.
Saturday Night Live sketchEdit
In his room at the Great Northern at 11:31 PM, Cooper addresses a tape to Diane, telling her how long he showered and the details, including how many hairs he found and what kind of shampoo he used. He then tells her that he ate fifteen jelly doughnuts and that he will soon take an insulin shot, then details his plans to slide around his sheets in the nude to figure out what they are made of.
Sheriff Truman then enters, announcing that Leo has confessed to Laura's murder. However, Cooper does not listen, instead suggesting that they go to One Eyed Jack's disguised as Indians, using Hawk's buckskins. The sheriff tells him of Leo's confession again and Cooper says it to be another piece of the puzzle of figuring out Laura's killer. Harry tells him that they have evidence, including a videotape of Leo murdering Laura, but Cooper again dismisses this as it is too obvious. He then tells of a dream he had of a hairless mouse with a pitchfork singing a song about caves and surmises the caves to be the same ones at the Packard Sawmill.
Deputy Andy brings a handcuffed Leo into the room, who says he is ready to do his time. Cooper determines Leo's actions to make him a prime suspect. Leland Palmer then enters, thanking him for finding the man who killed Laura. However, Cooper tells him that Laura's killer is still at large, which causes Leland to have a breakdown and he leaves. 
Audrey then enters. Cooper asks her if she has found any leads at the perfume counter, but she say she quit the job after Leo confessed. Leo interrupts and shows pictures of him about to kill Laura, killing Laura, and wrapping Laura in plastic. However, Cooper is still unconvinced. Audrey gives him a present, tying the bow with her tongue, and she leaves.
Cooper turns to Harry, telling him of his plan to stake out the graveyard, disguised as altar boys. The sheriff shoots this plan down and continues trying to convince him that Leo is guilty of the crime. Cooper suggests that he throw a rock at a window, suggesting that if it breaks, Leo is innocent. He throws the rock, breaking the window, and tells Leo he is free to go. This irritates Leo, who says he sent several notes to Cooper, confessing to the crime.
Nadine Hurley then enters and asks him to take her silent drape runner to the patent office in Washington, D.C. then leaves. Harry says he is about to head out as well, but Cooper stops him, as they have not yet heard from the Log Lady. However, Harry says they will not hear from her, as they have already used both female Saturday Night Live cast members. Nevertheless, she comes in to tell him that her log points to Leo being the murderer and she leaves.
Sheriff Truman prepares to leave with Andy and Leo, but Cooper then says that they still have to figure out who shot him, which Leo also confesses to. They leave Cooper alone and he addresses another tape to Diane, telling her of his impending return. He says that he feels alone in Twin Peaks for the first time. The little man from his dream then enters. Cooper says he is off to get a pie from the diner, but then decides to go to bed as the man dances.
Ken comes to Cooper, searching for his missing wife, Asami, who had sent a postcard from the Great Northern prior to her disappearance. In her room, investigators found a deer head and a photo of Asami. Cooper suggests they think about this over coffee. Andy and Lucy began to bring in coffee, but he rejects this in favor of Georgia Coffee, which he highly praises. Ken asks about the deer head, and Cooper notices a symbol that resembles the sign at Big Ed's Gas Farm.
Cooper and Ken find Asami's car, a rare Von Singer Vibel, and in the front seat is a triangle of red snooker balls. They go to the Double R Diner, where Cooper rejects Shelly's coffee for a can of Georgia Coffee. Shelly then gives Ken an origami swan, left by "a beautiful woman."
A Mystery of "G"Edit
Cooper tries to figure out the meaning of the swan and finds the letter 'G' on it, which makes him suggest they think it over with some Georgia Coffee. When Andy connects pins on a map, Hawk identifies the location as Glastonbury Grove.
Cooper travels with Ken to the grove and enters the Black Lodge and rescues Asami. They celebrate with Georgia Coffee.
Behind the scenesEdit
Cooper is portrayed by Kyle MacLachlan, who had previously starred in the David Lynch films Dune and Blue Velvet. MacLachlan considers Cooper to be an older version of his character from the latter film, Jeffrey Beaumont.
For his performance as Agent Cooper, MacLachlan won a Golden Globe for Best Actor in a Drama Series and was nominated for an Emmy for Outstanding Lead Actor in a Drama Series.
MacLachlan reprised the role in the revival series.
- According to Mark Frost, Cooper's personality and characteristic quirks are based on Lynch. He was also conceptualized as a modern Sherlock Holmes.
- Cooper's car (seen only in the pilot episode) is a 1981 Dodge Diplomat.
- Following the close of the Laura Palmer case, the show was to focus on the relationship between Agent Cooper and Audrey Horne. However, MacLachlan refused this on the grounds that Cooper would not allow himself to be romantically involved with a high school student. As a result, the characters of John Justice Wheeler and Annie Blackburn were introduced and the show further focused on the supporting characters. It was later rumored that Lara Flynn Boyle had some influence on this, as she was dating MacLachlan at the time and allegedly did not get along with Sherilyn Fenn.
- As intended by Lynch and Frost, the Collectible CardArt and Twin Peaks: An Access Guide to the Town establish Cooper's middle name to be Bartholomew, making him share initials with D.B. Cooper, the media's name for a 1971 plane hijacker who identified himself only as Dan Cooper.
- In Episode 6, Blackie O'Reilly tells Cooper that he looks like Cary Grant. Coincidentally, Kyle MacLachlan went on the portray the spirit of Cary Grant in the 2004 film, Touch of Pink.
- Cooper was originally to have investigated the Teresa Banks murder and this was portrayed as such in The Autobiography of F.B.I. Special Agent Dale Cooper: My Life, My Tapes. However, in Twin Peaks: Fire Walk with Me, Chester Desmond and Sam Stanley are given the case. This was a result of MacLachlan's wish to have a smaller role in the film.
- Unrealized plans for the original series' third season would have seen Cooper retire from the FBI following his release from BOB's possession. He would have then become the local pharmacist in Twin Peaks.
- The idea of Cooper being without his suit for a time was pushed by MacLachlan.
References in other mediaEdit
- A character resembling Cooper makes an appearance in the video game Blair Witch Volume 1: Rustin Parr. He is sitting in the Burkettsville diner eating pie and later in the game drinking "a damn fine cup of coffee." His name is given as "Hale" when communicated with.
- The 2010 video game Deadly Premonition (titled Red Seeds Profile in Japan) is heavily influenced by Twin Peaks. This is mostly apparent with its protagonist, FBI Special Agent Francis York Morgan. Agent Morgan is an FBI Agent assigned to a case in which a teenage girl was murdered in the small Washington town of Greenvale. Much like Cooper, York enjoys a hot cup of coffee and often speaks to a mysterious unseen person - in this case, named Zach.
