Castiel: Do you think Claire is in trouble?
Dean Winchester: She's hanging out with a guy named Randy. She's in trouble.
Crowley: You said you'd be back in a flash and then you disappeared. I was eight years old! Eight!
Rowena: Oh, now you're being dramatic.
Crowley: I didn't even have a father!
Rowena: Of course you had a father! You were just conceived during a winter solstice orgy and it's not like I was taking names.
Sandra Phelan: What is it that you do exactly?
Castiel: I... um... I fight certain deadly threats to humanity.
Claire Novak: He's an exterminator.
Castiel: I'm an exterminator.
Dean Winchester: Cass, I need you to promise me something.
Castiel: Of course.
Dean Winchester: If I do go dark side, you gotta take me out.
Castiel: What do you mean?
Dean Winchester: Knife me. Smite me. Throw me into the freaking sun, whatever. And don't let Sam get in the way, because he'll try. I can't go down that road again man. I can't be that thing again.
