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

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

Dean: Cas, hold up. What were te 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, te poor, stupid son of a b*tch! It's just a way for your bosses to keep me and keep te in line! te 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.
Castiel: I dragged te out of hell, I can throw te back in.

Dean: (On Castiel trying to find God) Try New Mexico, I hear he's on a tortilla.

Castiel: No, he's not on any flatbread.

Raphael: I will find you!

Castiel: Maybe so, but today you're my little b*tch.
