Lucy Moran is a high-voiced, slightly immature blonde receptionist at the Twin Peaks Sheriff's Department. She is seeing deputy sheriff Andy Brennan, until they have an argument. She reveals later that she was also seeing Dick Tremayne, who works at Horne's Department Store, after feeling frustrated with Andy.
One day, Lucy called Andy and Sheriff Harry S. Truman over the intercom to let them know that Josie Packard claimed she heard a prowler. Harry, apparently being summoned for one of his regular rendezvous with Josie, left Andy in the room with the doughnuts. Lucy continued speculating over what the prowler may have been, not realizing Harry had already left the room, resulting in her screaming with surprise when he showed up right in front of her. Andy, hearing this scream, ran to see what the trouble was, while Lucy continued to speak over the intercom asking if he was still there. She then left her desk and they ended up colliding in the hallway.
Later, she received a call from Andy, who helped find a train car where the murder took place. He told her to tell Harry that he did not cry and she tried to comfort him.
She later listened in to a conversation between Bobby Briggs and Mike Nelson, who planned to beat a biker with the initial 'J.' When she went to report her finding to FBI Special Agent Dale Cooper, he was already steps ahead of her, as he saw the reflection of a bike in Laura's eye in a video taken of her.
When Donna was seen at the Roadhouse, Truman told her to send two backup units and to tell Hayward that his daughter was safe. When Truman brought in James Hurley for questioning, he had Lucy prepare an arrest form and she set out an arrangement of donuts for Cooper and Truman. After Truman recommended to Cooper that he stay at the Great Northern Hotel, Lucy gave him directions.
When Agent Cooper arrived at the sheriff's station in the morning, she ate breakfast and told him that she got him jelly donuts and that Sheriff Truman was waiting for him in the conference room.
The following day, she assisted Sheriff Truman and Deputy Hawk in setting up a bottle sixty feet and six inches from where she was standing, per Agent Cooper's orders. She offered all of the men coffee, to which they all enthusiastically accepted and Cooper highly approved of it. She watched Cooper's presentation of Tibet and a method he had derived from them to determine what individuals with the initial 'J' could have been involved in the case. He had Lucy put check marks next to the names when the bottle was hit. The rock for Doctor Lawrence Jacoby hit the bottle but did not break it. When the "Jack with one eye" on the list was determined to possibly mean the casino One Eyed Jack's, Lucy removed it from the list. Then when the rock was thrown for Leo Johnson was thrown, the bottle broke. Later, Albert Rosenfield arrived in Twin Peaks and impatiently had Lucy inform Agent Cooper of his arrival.
Lucy went with Sheriff Truman to the Great Northern Hotel the next morning to meet with Agent Cooper, who had stated to Harry that he knew who killed Laura Palmer. However, he did not remember the name of the killer.
The following day, Lucy intently watched Invitation to Love when Harry and Andy came. The sheriff asked her "what's going on?" and she responded with the events of the television show, but he clarified that he meant at the station and she told him Cooper was waiting in the conference room with Doctor Jacoby. When he went, Andy stays behind, asking why he could not spend the previous night with her, but she ignored the question and asked if he would be having coffee.
Lucy was told by Harry to look through files confiscated from the Lydecker Veterinary Clinic and to pull out the names of all of the bird owners. When Andy told her about a mishap he had with his gun, she brushed him off.
The next day, Lucy called in sick.
Andy came to see her at her desk the day she returned to work, but she again did not wish to engage in conversation with the deputy. He left when she got a phone call from her doctor. Agent Cooper then arrived, commenting on her being out sick the previous day. She later went to the conference room when it was found that the myna bird, Waldo, had been shot.
The next day, Lucy watered the plants at the sheriff's station as Ed Hurley and Deputy Hawk talked about Andy's heroic actions of saving the life of Sheriff Truman. Impressed, she went to the kitchen area, where Andy joined her, closing the divider behind him. They kissed until Lucy announced that she was pregnant. She went back to her desk and received a call apparently from Leo Johnson, who asked for the sheriff and said to check out James Hurley, who was an "easy rider." When Sheriff Truman returned to the station, she told him about this phone call.
After Agent Cooper was brought to the hospital with a gunshot wound, she stood over him with Doctor Hayward and Sheriff Truman as he came to in the morning. Truman told her to inform him that Leo Johnson had been shot, Jacques Renault was strangled, Shelly Johnson and Pete Martell had suffered smoke inhalation, Catherine Martell and Josie Packard are missing, and Nadine Hurley was in a coma from overdosing on sleeping pills. With Truman, she followed Cooper, who had left his hospital bed to resume work, against Hayward's wishes.
She was present in the conference room as Cooper went over the events that occurred the night Laura died. She smiled proudly as Andy stood up to Albert Rosenfield and his insults.
The following day, a fly buzzed around the receptionist's desk, much to Lucy's annoyance. Andy came in and reveals to her that he is sterile and asked how she was having a baby under this circumstance. She leaned closer to him, and while he assumed to be receiving a kiss, Lucy pulled a piece of tape off of Andy's head and shut the window.
She later patched through a phone call from Benjamin Horne. The station received another call, this time from someone who refused to reveal their identity, wishing to speak to Sheriff Truman. She hung up.
Lucy overheard Agent Cooper telling James to stop trying to solve Laura's murder on his own. He also checked on her as she figured out how many words contained the letters found under the fingernails of Teresa Banks, Laura Palmer, and Ronette Pulaski. Hawk came to check on her work just before Dick arrived to take her out to lunch. Hawk gave him the cold shoulder and left before they went to lunch at the Double R Diner.
At the diner, Dick bored Lucy with his talking about his work and the way he used his fork. She then displayed her annoyance with the fact that he had not called her in weeks despite how exciting their relationship had become. He then discussed a way to make it up to her and she proposed a maternity dress, informing him of her pregnancy.
She collided with Andy in a hallway at the station the next day. She noticed that he had an issue of Flesh World and was on his way to the bathroom. Disgusted, she shoved the book at him and left in a huff to the receptionist's desk.
Lucy was later approached by Andy and was still upset over catching him with the magazine. Agent Cooper came and dismissed Andy so he could talk to Lucy about her behavior as of late. She complained about the things she did not like about Andy and explained her relationship with Dick Tremayne, which had while she and Andy were on a break. He asked if she wanted to get back with Andy, but she did not know and became upset, then left the area.
Later, she drinks a coffee during a storm as Judge Clinton Sternwood arrived at the station and greeted her, asked for a hug, and noticed that she was upset. Sheriff Truman then arrived, followed by Agent Cooper. The three men went as Dick arrived, saying that he was ashamed of his own behavior and gave her $650 for an abortion. This upset her and she kicked him out of the station, giving his money back.
Lucy went to Sheriff Truman in the morning to tell him that she would be leaving to see her sister, Gwen in Tacoma, as she and her husband had a baby the previous week. She reluctantly left, escorted by the sheriff.
She returned to Twin Peaks a few days later with her sister, and they went to the sheriff's station, Gwen carrying her son Carl and discussing an infection she had. Lucy asked Hawk if he had seen Andy, but he shook his head.
Later, Andy came to the sheriff's station and saw Lucy holding her nephew, which caused him to faint. She held ice to his head as Gwen rambled on and interrupted Andy's wishes to talk with Lucy in private until they told Gwen to shut up. She went away and Andy told Lucy that he could very well be the father of her child, as he had his sperm re-counted.
Andy went to her the next day, wishing to talk about their child, but she confirmed to him that it may have not been his.
Dick came to see her at the station and she took him to a room with Andy, where she told them she wanted full cooperation from both of them throughout her pregnancy. This occurred as Leland Palmer confessed to his daughter's murder and subsequently died in custody.
Dick announced to her the next day that he had quit smoking and wished to speak about the baby while Lucy changed fluorescent light bulbs. Andy intervened, stating that there should not be any fighting between them.
As Agent Cooper prepared to leave Twin Peaks, he gave Lucy his best wishes for her and the baby and wished to be invited to her wedding. However, Cooper was stopped by Special Agent Roger Hardy, who told him he had been suspended from the FBI.
A couple of days later, Lucy sat down with Judy Swain, Andy, and Dick. Judy was the case manager for Nicky Needleman, an orphan who was under Dick's care and may have been traumatized by his parents' mysterious deaths.
Dick came back to the station in the evening and passed by her to speak with Andy.
The next day, Lucy overheard a conversation between Andy and Dick, but they were gone when she came to investigate. She was instead met by Cooper, who had assigned her to search newspapers for a chess deal of any information about a Windom Earle.
Later at night, Lucy explained to Truman that the station's power was out due to a bomb in the woods.
The following day, Andy informed Lucy that he and Dick believed that Nicky murdered his parents when he was six years old, but Lucy did not believe the boy to be capable of this.
In the evening, Doctor Hayward forced her, Andy, and Dick together for a meeting. The doctor shot down the accusations that Nicky murdered his parents, informing them that the boy was conceived by a rape, his mother died in childbirth, and his adoptive parents were killed in a car accident.
A couple of days later, Sheriff Truman had Lucy call Pete to the station and to check the newspaper for any chess moves by Windom Earle.
During Pete's work, he had Lucy and Andy start playing chess. She became frustrated when he moved one of his knights without doing the "little hook thing," as he believed it was optional, though Pete corrected him. She then put Andy in check.
Lucy went to Dick's wine-tasting event the next day, again sponsored by the Stop Ghostwood campaign. There, she became fed up with Dick's snootiness.
The day after the wine-tasting, she asked Andy for advice on her speech for the upcoming Miss Twin Peaks Contest and told him that the next day, she would choose whether he or Dick would act as her baby's father, regardless of who it belonged to biologically.
As the judges decided on the winner, Lucy took Andy and Dick aside to announce to them that she had chosen Andy as the father of her child. Dick congratulated Andy and then went to make his vote for Miss Twin Peaks. Andy told Lucy that he was excited for his responsibility of being a father, but excused himself to talk to Agent Cooper. Following Annie Blackburn's win, chaos ensued.
Back at the station, Andy asked Lucy if she was scared, and she confirmed this by expressing her worry that the lights at the Roadhouse were going out and that she was afraid that the same thing would happen in a hospital elevator when she was in labor. Andy declared that if this happened, he would be with her and help her have the baby inside the elevator. They shared a kiss and, for the first time, said "I love you."

At her home, she plays with a paddle-ball as Andy plays trumpet. She gets a phone call from Leland Palmer, who is trying to contact Sheriff Truman. He tells her that his wife believes she saw Laura's killer. She says she will contact Truman and Deputy Hawk as soon as she hangs up. Lucy hangs up the phone, then calls Sheriff Truman in his cruiser to tell him about Leland's call.
She then calls Agent Cooper to tell him of Leland's call. He tells her to have Harry get the sketch of the killer and go to the hospital.
A Mystery of "G"Edit
When Cooper suggests the same again, Lucy brings in several cans of Georgia Coffee.
