Working title: "Back to the Future II"

Dean: Really? Anna?
Castiel: It's true.
Dean: So she's gone all Glenn Close, huh? That's awesome.
Castiel: Who's Glenn Close?
Dean: No one. Just this psycho bitch who likes to boil rabbits.
Sam: So, the... the plan to kill me--would it actually stop Satan?
Dean: No, Sam, come on.
Sam: Cass, what do you think? Does Anna have a point?
Castiel: No. She's a... "Glenn Close."

Dean: What exactly are we gonna march up there and tell 'em?
Sam: Uh, the truth.
Dean: What, that their sons are back from the future to save them from an angel gone Terminator? Come on, those movies haven't even come out yet.

Anna: I need you to kill some humans.
Uriel: Always happy to do some smiting.

Michael: And you think you know better than my father? The one unimportant little man. What makes you think you get to choose?
Dean: Because I got to believe that I can choose what I do with my... unimportant little life.
Michael: You're wrong. You know how I know? think of a million random acts of chance that let John and Mary be born, to meet, to fall in love, to have the two of you. Think of the million random choices that you make--and yet how each and everyone of them brings you closer to your destiny. Do you know why that is? Because it's not random. It's not chance. It's a plan that is playing itself out perfectly. Free will's an illusion, Dean. That's why you're going to say yes.

Dean: Well... this is it.
Sam: This is what?
Dean: Team Free Will. One ex-blood junkie, one dropout with six bucks to his name, and Mr. Comatose over there. It's awesome.
Sam: It's not funny.
Dean: I'm not laughing.
