Sam: How you feeling?
Dean: Word to the wise. Don’t piss off the nerd angels.  So how’s it going? Sam: Adam’s gone. Angels have him.
Dean: Where?
Sam: The room where they took you.
Dean: You sure?
Sam: Cass did a recon.
Dean: And?
Sam: And the place is crawling with mooks. It’s pretty much a no-shot-in-hell, Hail-Mary kind of thing.
Dean: So the usual. What are you gonna do?
Sam: For starters bringing you with. (Sam unlocks Dean from the handcuffs)
Dean: Excuse me?
Sam: There are too many of them. We can’t do it alone and you’re pretty much the only game in town.
Dean: Isn’t that a bad idea?
Sam: Cass and Bobby think so. I’m not so sure.
Dean: Well, they’re right. Cause either it’s a trap to get me there to make me say yes. Or it’s not a trap and I’m gonna say yes anyway. And I will. I’ll do it. Fair warning.
Sam: No, you won’t. When push shoves, you’ll make the right call.
Dean: You know tables were turned, I’d let you rot in here. Hell, I have let you rot in here.
Sam(sighs): Yeah, well, I guess I’m not that smart.
Dean: I don’t get it, Sam.  Why are you doing this?
Sam: Because. You’re still my big brother.
