Olivia: If you can't trust the people you're dealing with, what then?
Bolivia: You know, maybe I'm not the problem. Maybe it's you. Maybe you are just incapable of trust.

Bolivia: You know, being you and living your life only made me more homesick for my universe.
Walter: The thing about playing Devil's advocate, my dear, is that your client is the Devil himself.

Lincoln: I'm coming with you.
Olivia: You keep going like this and you're gonna talk yourself out of the bureau.
Lincoln: I was at the first crime scene. Maybe I saw something that I haven't told you yet. Maybe that's why I came here.
Olivia: Okay, come. You can get fired later.
Walter: I need to check her anus. Have that large lady there help you lift here.

Astrid: Listen to this. One of the victims' credit cards just registered a charge. Dead people do not use their credit cards.
Walter: Of course they do. Certainly.
Lincoln: (about Walter) Is he all right?
Olivia: Well, that depends on your definition of all right. He's functional. Except when he's not. But he is often quite brilliant. He just never had anything to tether him to the world.
