[In a Season 1 episode of Fringe, Olivia has been thinking that she’s losing her mind because she’s having dreams where she sees people being murdered, and when she later wakes up and goes to her job as an FBI agent, she finds that they have been murdered. But now they’ve found a potential suspect named Nick Lane, which leads to Olivia and Peter sitting in the lobby of a mental hospital, waiting to meet a doctor there.]
PETER: You know, until this year I’d never actually been to a mental hospital.
OLIVIA: [Bent over, her head in her hands, looking at the floor] Learn to like new things.
PETER: Maybe I never gave it enough thought ... what Walter went through. I only ever saw it through my own perspective. His being crazy was something that he did to us. To my mother and me. It wasn’t something that happened to him.
OLIVIA: Well, you were young.
PETER: Well I’m not young any more. [long pause, looking off into the distance] It must be a terrible thing to not be able to trust your own mind. [sighs]
OLIVIA: Yeah ... [rubs her hands together, then puts her head in her hands again]
