What the f*ck did you do?

"Dissonance Theory"

Sylvester mocks Lutz for trying to fix a broken bird. He scolds Lutz for stealing the bird in the first place and tells him that he will never be anything more than a simple butcher.[2]

"The Adversary"

work in progress

"Trompe L'Oeil"

Sylvester is tasked with decommissioning Clementine Pennyfeather. As he performs the procedure he spots Maeve and Lutz through one of the glass walls of Behavior Lab and Diagnostics, and meets up with them in one of the empty rooms. He tries to make an excuse for why he performed the decommissioning, but is unable to give a good reason. Maeve tells him and Lutz that they're going to help her escape, and when he protests that it's a suicide mission, Maeve threatens to kill him if he doesn't help her.[3]


Sylvester is a very pessimistic, negative person. He constantly worries about his job, and mocks Lutz for trying to improve his skills and thus earn a promotion, showing he doesn't believe people can change. He is a bit cowardly, as when Maeve threatens to kill him he just stares fearfully at her.

He is content to be a butcher at Westworld, and isn't very ambitious.


Felix Lutz

Sylvester sees Lutz as a clumsy assistant, rather than a coworker. He doesn't like him very much, mocking him for trying to better himself and becoming angry when Lutz apparently forgets to put Maeve into sleep mode.
