Alin: Before you go on a journey of revenge, dig two graves.
Peter: I'm not worried about being destroyed. It's the Observers who should be worried.

Peter: I can feel you banging around inside there. But it doesn't matter what you find out, 'cause you and I both know... you're never walking out of here. Whatever the closest thing it is to fear that you can feel, I know that you're feeling it right now. You're not the only one with a skill for reading people.
Captive Observer: You don't even know what you don't know.
Peter: We'll see.

Captive Observer: I think of you as I would an ant colony as I pass by it. I don't care about the workings of the colony, why one ant is mad at or another or why one ant would kill another or not. To me, it is insignificant. And like an ant colony, you are oblivious to your limitations. You think the black over your head is dark skies... when it is really our shoe.

Walter: I have experience with this--this sort of pain, and you can't escape it by building walls around your heart. Or by breaking the universe. Or by vengeance.
