Thredson: Sure you won't change your mind?
Lana: You think I'm crazy. Oh, wait. That'd be you. I think we established that when you chained me to the bed and called me Mommy.
Sister Jude: It's an extraordinary thing. You know that? You throw me in the madhouse, you strip away everything I have, everything I know, you treat me like a rabid dog, like a madwoman. And you know what happens? I'm blessed with the gift of total clarity. I am more sane now as a madwoman than I ever was as the head of Briarcliff.
Detective Byers: You're one tough cookie, you know that?
Lana: I am tough. But I'm no cookie.
Thredson: But you know what, Lana? We'll always have Paris.
The classic line in 1942's Casablanca is "We'll always have Paris," spoken by Rick Blaine (Humphrey Bogart) to Ilsa.
