Castiel: Fight this!
Sam Winchester: Why? I'm happy in Charming Acres. We're all happy.
Castiel: Sam, I know you want to be happy. And I know what it's like to lose your army. I know what it's like... to fail as a leader, Sam. But you can't lose yourself. You have to keep fighting. You can't lose yourself, because if you do, you fail us. You fail all of those that we've lost. You fail Jack. Sam, you fail Dean.
Castiel: Sam, I don't know what's happened. I don't know if this is a spell or a curse or... or what's happened, but you will snap the hell out of it!
Sam Winchester: Sir, you watch your mouth. If we cannot remain civil, then you can skedaddle.
Sam Winchester: That's not my name! Cindy, grab his hat!
Castiel: I don't wear a hat!
Mrs Smith: Honey, I don't think he wore a hat!
Sam Winchester: Fine! Sir, using language like, uh, "H-E-double hockey sticks"... You should have your mouth washed out with soap.
Sam Winchester: It's Justin.
Castiel: I'm gonna... Double hockey sticks?
Castiel: I'm looking for my partner.
Mrs. Dowling: Oh. The very nice, the very tall fella?
Mrs. Dowling: Hm. He said he's going for a walk. And a milkshake.
(Later... in the milkshake place)
Castiel: I'm looking for my partner.
Sunny Harrington: Who?
Castiel: The man I came in with yesterday.
Sunny Harrington: Oh, the tall man.
Castiel: Yes, the very tall man.
(Later... at the Smith residence)
Castiel: I'm looking for my partner. The tall man. Hair? He has beautiful hair?
Mrs Smith: What?
Castiel: Uhh. This is complicated.
Jack Kline: I can't... think about losing him or... or Sam or you. I-I just... I hate... I hate thinking about it.
Castiel: Yeah. So do I. But, Jack... you know, Sam and Dean, they're human, and they're very extraordinary, brave, special humans, but they're... They're still humans. And humans burn bright, but for a very brief time compared to, you know, things like us. And eventually, they're gone, even the very best ones, and we have to carry on. It's just... It's part of growing up.
Jack Kline: Losing people?
Jack Kline: What's the point?
Castiel: The point?
Jack Kline: What's the point of being a cosmic being if everyone I care about is just gonna... leave?
Castiel: The point is that they were here at all and you got to know them, you... When they're gone, it will hurt, but that hurt will remind you of how much you loved them.
Jack Kline: That sounds... awful.
Castiel: It is. But it's also living. So when Dean wakes up... And he will wake up... We just have to remember to appreciate the time that we all have together now.
Gorgon: Have you ever heard the story of the black snake? Once there was a crafty black snake who kept eating this poor chicken's eggs. She couldn't watch them all the time, you see? The black snake would wait until she was gone... and then slide one of the eggs into his mouth and crush it in his throat. Now, this went on until there was only one egg left. But when the chicken left that egg, just for a moment, the snake swallowed it up. But for some reason, he couldn't crush it in his throat. The chicken had hard-boiled her final egg just to choke the snake. And the snake died.
Castiel: Why are you telling this story?
Gorgon: Because I can't quite tell if he's the chicken... or the snake. (meaning Jack)
Sam Winchester: Okay, so, we've made some progress.
Dean Winchester: This is like an A.V. Club presentation.
Jack Kline: What's an A.V. Club?
Castiel: It's a special group for people who do not play sports.
Dean Winchester: Yeah, him. (points at Cas) He's A.V. Club.
Rowena: Excuse me, boys, but this is a bit more pressing than your hilarious banter.
Castiel: Why do you hate this world enough to burn it to the ground?
Michael: Because I can. Because... Me and my brother... my Lucifer... when we fought in my world, we thought that God would come back, give us answers... why He'd gone, what we'd done... but, instead, do you know what happened? Nothing. No God. Nothing. And now... now that I'm in here... now I know why. God... Chuck... is a writer, and like all writers, He churns out draft after draft. My world? This world? Nothing but failed drafts. And when He realizes that they're flawed, He moves on and tries again.
Castiel: No, that's not how... Why would He do that?
Michael: Because He doesn't care! About you, me... anything. Now, at first, I thought I'd do it better. Show Him. Be more God than God. But now... I just want to burn every one of His little worlds until I catch up to the old man.
Castiel: And then what?
Michael: Even God can die.
