Gordon Cole, played by David Lynch, is a Regional Bureau Chief in the FBI and Agent Cooper's immediate superior. He is very hard-of-hearing (wearing large hearing aids) and thus speaks very loud. He often misunderstands what is said to him and replies with comically inappropriate responses. Cole’s coded messages sometimes baffle even his closest colleagues. In the first episode he appears, he says, “Cooper, you remind me today of a small Mexican chihuahua.” The conversation continues as normal, with the issue remaining unsolved.
At the beginning of Twin Peaks: Fire Walk with Me, Cole briefs agents Chester Desmond and Sam Stanley on their assignment to investigate the murder of Teresa Banks. Cole uses a coded language, in the attire and gestures of Lil the Dancer, to inform the agents of what to expect in their investigation. Cole describes the Teresa Banks murder case as one of his “blue rose” cases. The exact meaning of this is never given, but fans have speculated that a “blue rose” case is one involving the supernatural.
