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.
Michael: When I gave up Dean, you didn't think to question it, to ask why? Dean was... resisting me. He was too attached to you, to all of you. He wouldn't stop squirming... to get out, to get back. So I left... but not without leaving the door open... just a crack.
Castiel: Why wait?
Michael: To break him, to crush and disappoint him so completely that, this time, he'll be nice and quiet for a change... buried. And he is. He's gone. And now... I have a whole army out there, waiting, ready for my command, ready...for this. (snaps his fingers)
Castiel: You know, The Empty said that it wouldn't come for me until I had finally given myself permission to be happy, but with everything we have going on, with... with Michael still out there, I don't see that happening anytime soon. This life may be a lot of things, but it's rarely happy.
Jack: I'm sorry.
Castiel: Hey. At least we have Krunch Cookie Crunch.
Jack: Yeah. We do. Did you take the decoder ring out of the box?
Castiel: Maybe. The secret password is... "Cookietacular."
Jack: Why? Why did you do that?
Castiel: Because I made a promise. Because I love you, Jack. And Sam and Dean... they love you. And they are fighting for you at this very minute. I hope that... They don't need to know what happened here. What I did... I'm... I'm... I'm at peace with my choice. I don't want them to worry.
Jack: I won't tell them. I promise.
Castiel: The plan is to subdue him using angel cuffs and spell work. They have to get Michael out of Dean.
Jack: And if he doesn't leave?
Castiel: Then they'll try to drive him out.
Jack: And if that doesn't work?
Jack: Cas, Michael has to be stopped.
Castiel: I know, and he will be, after Dean is...
Jack: No, Dean doesn't matter. You're all so focused on trying to save Dean. And I get it, I understand, but if he can't be saved, if it comes down to him or Michael... Michael has to be stopped. Caged or killed...
Castiel: And if that means that Dean dies, too!?
Jack: Then Dean dies. I know this Michael. I've seen what he's done to an entire world, and so have you. If stopping that from happening here means that Dean has to die, then... Do you think he'd want it any other way?
