Frank: When something feels that good, does a person ever just do it once?
Chance: No. Especially if it's part of a shared psychosis.
Frank: I'm sorry. What'd you call me?
Chance: Folie a deux. Madness of two people. One individual is psychotic, is dominant. The other one is suggestible, susceptible. They're both operating under the same delusion. Winter's madness drove him, but you exploited it, you captialized on his trauma for your own purposes. He wanted to get out of it, but you made sure that he wouldn't. Couldn't. All the way to the end.
Frank: Why would I do that? Hmm? Why would I do any of that?
Chance: Because you wanted to. Because you like it. Because you're entire neural network is conditioned to that now. When you were entrenched with Winter, your reactions, sexual and psychological, were all responses to power and terror. Now he's gone. So you're alone with you desires, your responses. You're going to be staring down the barrel of the rest of your life without anyone to help you achieve them. What a thing it is, in life, to find even one person who understands your darkest heart, let alone two.
Frank: You're right. He is gone, but I'm not alone. I wouldn't do that to myself. Come on, Doc. You think I don't know how to plan for contingencies? You know, if there's one thing that I've learned from my job, it's how to prepare. It's how to play the long game, right? He is gone, but I'm not alone.
