Dean: You guys don't walk enough. You're gonna get flabby. You know, I'm starting to think Junkless has a better sense of humor than you do.

Castiel: Uriel's the funniest angel in the garrison. Ask anyone.

Dean: Cas, hold up. What were you going to tell me?

Castiel: I learned my lesson while I was away, Dean. I serve Heaven, I don't serve man. And I certainly don't serve you.

Dean: Destiny? Don't give me that "holy" crap. Destiny, God's plan... It's all a bunch of lies, you poor, stupid son of a b*tch! It's just a way for your bosses to keep me and keep you in line! You know what's real? People, families - that's real. And you're gonna watch them all burn?

Castiel: What is worth saving?! I see nothing but pain here. I see inside you. I see your guilt, your anger, confusion... In Paradise all is forgiven. You'll be at peace. Even with Sam.

Dean: What He Said

Dean: Ass-butt?

Castiel: He'll be back, and angry, but you got your five minutes

Lucifer: Castiel, Did you just Molotov my brother... with Holy Fire?

Castiel: Uh... no?

Lucifer: No one dicks with Michael but me.
