Sam asks Dean if Castiel touching the angel tablet broke Heaven's control over him. However, as Dean saw earlier, Castiel spared Dean's life and then picked up the tablet. Neither Sam nor Dean would have any reason to think touching the tablet had anything to do with Castiel's freedom.
Sam: What is wrong with you?
Dean: What's wrong with me? You kidding me? This is a first edition, dude. Do you know what this would go for on eBay?
Sam: Nope. Why, do you?
Dean: No. Maybe. Shut up.
Dean: Well, he puts the "ass" in "Cass," huh?
Sam: Wait a second. You've been telling Crowley the location of Lucifer's Crypts.
Meg: What can I say? I needed a break from the constant torture.
Sam: Wait--so... a bunch of innocent people died so you could buy yourself some time?
Meg: Hi, I'm Meg. I'm a demon.
Sam: Wait a second. Did you just say, "angel tablet?"
Meg: You know, I get why Crowley calls you "Moose" now.
Castiel: These wounds have festered.
Meg: You really do know how to make a girl's nethers quiver, don't you?
Castiel: I am aware of how to do that. Although it doesn't usually involve cleaning wounds.
Meg: Why are you so sweet on me, Clarence?
Castiel: I don't know. And I still don't know who Clarence is.
Meg: Would it kill you to watch a movie, read a book?
Castiel: A movie, no. But a book with the proper spells... yeah, it could theoretically kill me.
Meg: You know, you're much cuter when you're shutting up.
Meg: So, your noodle's back in order?
Castiel: Yeah, my noodle remembers everything. I think it's a pretty good noodle.
Meg: Really? You remember everything?
Castiel: If you're referring to the pizza man... yes, I remember the pizza man. And it's a good memory.
Meg: I miss the simplicity. I was bad. You were good. Life was easier. now it's all so messy. I'm kind of good, which sucks. And you're kind of bad... which is actually all manner of hot. When we survive this... I'm gonna order some pizza and we're gonna move some furniture around. You understand?
Castiel: No, I--I... wait. Actually, I...
Dean: (coming in) All right, let's roll, campers.
Meg: Hold on, there's one part I don't understand. You hit a dog and stopped. Why?
Sam: That whole story, and that's your takeaway?
Meg: Oh, I heard the rest. You fell in love with a unicorn. It was beautiful, then sad, then sadder. I laughed, I cried, I puked in my mouth a little.
Crowley: Castiel. So, that's who's been poking my boys... and not in a sexy way.
Crowley: I'm here for the stone with the funny scribbles on it.
Sam: That's not gonna happen.
Crowley: Love it when you get all tough. Touches me right where my bathing suit goes.
Crowley: Naomi. Fancy meeting you here. Haven't seen you in a dark age. Love the haircut.
Dean: Listen, I may not be able to carry the burden that comes along with these trials, but I can carry you.
Sam: You... realize you kind of just quoted Lord of the Rings, right?
Dean: Come on, man, but it's the Rudy hobbit. Rudy hobbit always gets a pass. Shut up.
