Episode Quotes
Dean: Home, crappy home.
Uriel: Winchester and Winchester
Dean: Oh, come on!
Uriel: You are needed.
Dean: Needed? We just got back from needed!
Uriel: Now, you mind your tone with me.
Dean: No, you mind your damn tone with us.
Sam: We just got back from Pamela's funeral.
Dean: Pamela, you know, psychic Pamela? You remember her. Cass, you remember her. You burned her eyes out. Remember that? Good times!

Dean: I want to talk to Cass alone.
Uriel: I think I'll go seek... revelation. We might have some further orders.
Dean: Well, get some doughnuts while you're out.
Uriel: Ah, this one just won't quit. I think I'm starting to like you, boy.

(Uriel flies away)
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.

Alastair: They sent you to torture me?
Dean: You got one chance. One. Tell me who is killing the angels. I want a name.
Alastair: You think I'll see all your scary toys and spill my guts?
Dean: Oh, you'll spill your guts, one way or another. I just didn't want to ruin my shoes.

Alastair: Go directly to Hell. Do not pass Go. Do not collect $200.

Alastair: Sorry. Something caught in my throat. I think it's my throat.

Castiel: Lucifer is not God.
Uriel: God isn't God any more.

Castiel: You can't win, Uriel. I still serve God.
Uriel: You haven't even met the man. There is no will. No wrath. No God.
Anna: (stabbing him) Maybe, maybe not. But there's still me.
