Albert Rosenfield, played by Miguel Ferrer, portrays himself to others as a cynical city slicker forensics specialist in the FBI who appears to have grown insensitive and indifferent to other people and has contempt for the rural lifestyle of Twin Peaks. However Rosenfield is revealed to be in fact a conflicted man who, although cynical, holds deep moral convictions.
The dialogue between Sheriff Truman and Albert Rosenfield:
- Albert Rosenfield: Oh yeah, well I've had about enough of morons and half wits, dolts, dunces, dullards and dumbbells ... and you, you chowder-head yokel, you blithering hayseed. You've had enough of me?
- Sheriff Truman: Yes I have. [Punches Albert in face]
He also rowed with Doc Hayward, and was very disparaging about the capabilities of the local police and medical facilities in Twin Peaks generally, showing respect only to his FBI colleagues, at least at first. He warms up to the townsfolk as the series progresses, but does not lose his sharp and ironic manner.
- [Albert observes suspended Agent Cooper's plaid shirt and khaki slacks.]
- Albert Rosenfield: Oh, Coop, uh, about the uniform…
- Dale Cooper: Yes, Albert?
- Albert Rosenfield: Replacing the quiet elegance of the dark suit and tie with the casual indifference of these muted earth tones is a form of fashion suicide, but, uh, call me crazy — on you it works.
A later appearance, and another conflict with Sheriff Truman, led to an emotional moment where Rosenfield exposed a sensitive and peace-loving side, seemingly at odds with his acerbic surface persona and to the complete shock of the sheriff and viewers alike. Such complex, contradictory characters were typical of Twin Peaks and the works of David Lynch in general.
- Sheriff Truman: Anything we should be working on?
- Albert Rosenfield: Yeah. You might practice walking without dragging your knuckles on the floor. Heh heh heh.
- Sheriff Truman: Albert! Let's talk about knuckles. The last time I knocked you down, I felt bad about it, the next time's gonna be a real pleasure.
- Albert Rosenfield: You listen to me. While I will admit to a certain cynicism, the fact is that I am a naysayer and hatchet-man in the fight against violence. I pride myself in taking a punch and I'll gladly take another because I choose to live my life in the company of Gandhi and King. My concerns are global. I reject absolutely: revenge, aggression and retaliation. The foundation of such a method... is love. I love you Sheriff Truman.
- Dale Cooper: Albert's path is a strange and difficult one.
Next time he and the sheriff meet in the series they share a friendly hug, implying his message was taken in good faith and a bond had been formed.
In Twin Peaks: Fire Walk with Me, Albert had a minor role, and appeared in the F.B.I. offices with Gordon Cole during the reappearance of Phillip Jeffries. He also appears later on when Cooper predicts that Teresa Banks's killer will strike again, and the victim will be a woman, blonde, in high school, sexually active, using drugs, and crying out for help. Says Albert, "Well, damn, Cooper, that really narrows it down. You're talking about half the high school girls in America!"
He is also briefly in The Autobiography of F.B.I. Special Agent Dale Cooper: My Life, My Tapes, under the entry recorded on the 4th February 1978 - it is implied that this is he and Dale Cooper's first meeting. This makes Albert 22 when the two first meet, according to the My Life, My Tapes canon.
