  Andy Brennan is a sheriff's deputy in Twin Peaks. Andy is a bit slow on the uptake, even "dimwitted," very sensitive, and tends to cry at murder scenes. However, he is very loyal and trustworthy, and is compared to a dog by Albert Rosenfield.

He has an on-and-off-again relationship with the station's receptionist, Lucy Moran, though she truly is his greatest love.


Twin Peaks (1990-1991)Edit

Season 1Edit


When Pete Martell discovers a body wrapped in plastic, Andy is called to the scene to take pictures. He cries, but this is not the first time, as Sheriff Harry S. Truman notes that the same thing happened "last year in Mr. Blodgett's barn." He hands the camera to Doctor Hayward and is sent to get a stretcher as Hayward finishes his job and they identify the body as homecoming queen Laura Palmer.

Later, Andy sits with Deputy Hawk at Twin Peaks High School as they ask Laura's boyfriend, Bobby Briggs, about his whereabouts until Sheriff Truman arrives and informs him of Laura's death. Truman then has Andy assist Bobby to make a phone call to his parents to contact their lawyer.

Later, Andy goes with the sheriff to the Palmer home, where Truman questions Mrs. Palmer about Laura and Hawk searches for possible evidence. While there, they receive a call from Lucy that a mill worker named Janek Pulaski reported his daughter, Ronette missing.

Andy, along with other deputies, finds a train car where the murder took place. He calls Lucy in tears, requesting her to tell Harry that he did not cry.

When James Hurley is arrested, he and Hawk take him to his cell.

Episode 1Edit

Andy has breakfast, watching two men weld when FBI Special Agent Dale Cooper arrives at the sheriff's station.

Episode 2Edit

He helps Agent Cooper set up a demonstration he has prepared for the investigation, which he calls the "Tibetan method" and uses it to determine with individuals bearing the initial 'J' could be involved with the Laura Palmer case. Cooper has Andy stand near the bottle as he throws rocks towards them. The rock for Doctor Lawrence Jacoby knocks the bottle down, but does not break it. Andy puts it back into place. He is hit in the head when the rock for Shelly Johnson is thrown. The bottle then breaks when the rock for Leo Johnson is thrown.

Episode 3Edit

Andy contacts Sheriff Truman, informing him that a fight has broken out between Doctor Hayward and Albert Rosenfield at the morgue on whether Laura's body should be released for the funeral or kept for more tests. When it becomes physical, he is helped by the present Benjamin Horne to restrain them. The argument becomes physical once more before Sheriff Truman arrives with Agent Cooper. Truman punches Albert and Cooper orders the body be released, taking Hayward's side.

Andy comes to inform Sheriff and Truman when it is time for Laura's funeral.

Episode 4Edit

Andy sketches a gray-haired man that Sarah Palmer saw in a vision.

He returns to the sheriff's station with Harry, who goes to the conference to meet Cooper and Doctor Jacoby. Andy then asks Lucy why he could not spend the previous night with her, but she ignores the question, instead asking him if he will be having coffee.

After Jacoby leaves, Andy goes to the conference room and shows the finished sketch to Cooper and Truman. Cooper says that he saw this man in a dream he had. A call is then received from Hawk, who has seen a one-armed man that is wanted for questioning.

Andy goes with Cooper and Truman to the Timber Falls Motel, where the one-armed man, Gerard is staying. When they approach the room, Andy draws his gun but drops it, making it go off. Truman sends him away as he and Cooper kick in the door.

He looks around Gerard's hotel room, finding his sample case of right shoes.

When they go to the Lydecker Veterinary Clinic, Cooper asks Andy to go to the nearby convenience store to pick up twine, bringing him Finley's Fine Twine.

They bring back files from the clinic and he apologizes for what happened with his gun. He is told by Harry to meet in the pistol range, and on the way he sees Lucy, who brushes him off.

Cooper asks him about his current situation with Lucy, and he says he does not know why she will not talk to him. He then practices shooting, but is told he needs practice.

As he looks through the files with Harry and Cooper, Cooper's superior, Gordon Cole calls, saying that the bird they are looking for is either a parrot or myna bird. Andy then finds a file on a myna bird named Waldo owned by Jacques Renault.

Episode 5Edit

The next morning, Andy assists Sheriff Truman's investigation in Jacques's apartment and is ordered to get donuts for Agent Cooper, which he brings with a cup of coffee.

He then goes to the Johnson home and speaks to Shelly, asking about Leo's current whereabouts. She tells him that she overheard an argument about Laura between Leo and Jacques. He tells her to call the sheriff's department whenever Leo gets in touch with her then leaves.

When a gunshot rings out in the conference room, he goes in with the other lawmen to find that Waldo has been shot.

Episode 7Edit

Andy sits with Sheriff Truman on a stakeout, awaiting Jacques to cross the border. Harry asks him about his situation with Lucy, which has not improved. Jacques soon arrives and they arrest him, but he puts up a fight. He disarms an officer and nearly shoots Sheriff Truman, but Andy manages to calmly shoot him in the arm.

Later at the sheriff's station, he stands with Hawk, Ed, and some other lawmen as they discuss his heroic actions earlier in the evening. Lucy listens in and goes to the kitchen area.

When Albert Rosenfield returns comes to Leo Johnson's home, Andy calls out to Sheriff Truman, calling Albert "Agent Rosenflower." As he runs inside to warn Truman, he steps on a loose board, which smacks him in the face. Harry finds that this has revealed a hidden pair of boots and cocaine.

Back at the station, Andy goes to Agent Cooper and informs him that Leo had been imprisoned in Hungry Horse, Montana on February 9, 1988, which Albert notes to be the night Teresa Banks was murdered. This lessens Leo's status as a suspect in Laura's murder, if they were indeed killed by the same person.

Agent Cooper has Andy and Lucy search copies of Flesh World for a picture of Teresa Banks.

He sits in the conference room as Agent Cooper goes over the events that occurred the night Laura died. He cries, looking at a photo of Laura. Albert mocks him, which upsets him more. Now calling him "Albert Rozerfeld," he stands up to defend the Sheriff against his verbal attacks, then leaves.

After a small struggle for her to listen to him, he reveals to her that he is sterile and wishes to know how she is having a baby. Lucy leans closer to him, which he assumes to expect a kiss, but she instead pulls a piece of tape off of his head and closes the window on him.

Episode 11Edit

Andy confides in Doc Hayward that he needs to have a sperm test done. Doc gives him a vial to use for his sample and goes out to his car. On his way to the bathroom with an issue of Flesh World, he bumps into Lucy, who sees the magazine and their proximity to the bathroom and is disgusted with him.

He runs into another deputy and drops his sample, which rolls under a chair. He chases after it and Cooper tells him not to move. He asks Andy where he got his boots, which he says are from Philip Gerard. He gets his sample and leaves.

He later attempts to speak with Lucy, who is upset with catching him with the magazine. Cooper then arrives and dismisses him, and he watches through the window as the FBI man talks to Lucy.

With Lucy out of town to see her sister, Andy sits at the receptionist's desk and calls for his sperm test results. He is informed that he had oligospermia at the time of his previous test, but no longer has it. Realizing what this means, he declares "I'm a whole damn town!"

While going through sticky notes on the desk, he finds a number written under "Gwen and Larry," Lucy's sister and brother-in-law. He calls the number but is shocked to find that it is for Adam's Abortion Clinic.

Andy has coffee with Hawk, Cole, Cooper, and Philip Gerard - now displaying a different personailty: a spirit known as Mike - outside the receptionist's desk. Harry comes to tell them that everything is ready for their trip up to the Great Northern.

He goes with Cooper and Truman to the hotel, where he brings guests one-by-one to Mike to determine if they are the host of BOB, who is also a spirit. Mike has a seizure when Ben Horne enters the room.
