Andy Brennan

Andy Brennan is a character in the television series "Twin Peaks", played by Harry Goaz. Andy is a bit slow, even "dimwitted" deputy sheriff in the Twin Peaks Sheriff's department. He is very sensitive, and tends to cry at crime scenes. He is very loyal and trustworthy, and is compared to a dog by Albert Rosenfield.

Andy has been seeing the secretary of sheriff's department, Lucy Moran. She, however has grown tired of him, and seeks an adventure from seeing Dick Tremayne. Not much is revealed of Andy during the show, except perhaps through physical comedy, such as his inadequacy at handling guns and sticky tape. However, Andy later improves his gun toting skills by using the local range, and shooting Jacques Renault when he tries to go for Sheriff Truman.

Andy was the one who (at Season Two) figured out that the drawing was a map, and therefore had a big part in FBI agent Dale Cooper finding his way to the Black Lodge.

In the pilot, he is revealed as a trumpeter, albeit not a very good one. And he has a talent at drawing which we see demonstrated when he sketches Bob from Sarah Palmer's vision, and during the trial of Leland Palmer, when he sketches the back of Leland's head.
