Chuck: I've gotten what I want from hundred of Sams and Deans. I could get what I want from a hundred more. And I don't care. Those other toys, they don't... they don't... spark joy. But Sam and Dean... the real Sam and Dean... they do. They challenge me... they disappoint me... they surprise me. They're... the ones.
(Becky reads Chuck's new Supernatural story...)
Becky Rosen: B-But it's so... dark.
Chuck: But great, right? I can see it now... "Supernatural: The End". And the cover is just a gravestone that says "Winchester". The fans are gonna love it. Well?
Becky Rosen: It's awful! Horrible. It's hopeless. You can't do this to the fans. What you did to Dean...? What you did to Sam...?
Chuck: So I thought I'd come see you, my number-one fan. And, I don't know, see if you can help make me feel big again.
Becky Rosen: So, you want me to... fluff you?
Chuck: W... I mean, no.
Becky Rosen: You do. You thought you could just come back to me, your pathetic ex, your number-one fan, and get what you've always gotten from me... a nice big crank on your ego.
Chuck: Well, I mean...
Becky Rosen: Well, sorry, that's not me anymore, Chuck.
Dean Winchester: Why don't You just snap your fingers and end it?!
Chuck: Look, I...
Sam Winchester: And every other bad thing we've been killing, been dying over... where were you? Just sitting back and watching us suffer so we can do this over and over and over again... fighting, losing people we love? When does it end? Tell me.
Chuck: Dean, don't do this.
Dean Winchester: No, we're done talking. 'Cause this... this isn't just a story. It's our lives! So God or no God, you go to hell.
(Dean decides not to shoot Jack and throws away the gun...)
Chuck: No! Pick it up! Pick it up.
Dean Winchester: The hell, Chuck?
Chuck: This isn't how the story is supposed to end.
Castiel: The story?
Chuck: Lookit, the... the... the gathering storm, the gun, the... the father killing his own son. This is Abraham and Isaac. This is epic!
Dean Winchester: Wait. What are you saying?
Sam Winchester: He's saying he's been playing us. This whole time.
Chuck: Come on.
Sam Winchester: Our entire lives. Mom, Dad... everything. This is all you because you wrote it all, right? Because... Because what? Because we're your favorite show? Because we're part of your story?
Dean Winchester: And you're here because...
Castiel: Because of Jack.
Chuck: Listen, you guys know me. I'm hands-off. I built the sandbox... you play in it. You want to fight Leviathans? Cool. You got that. You want to go up against... what was it?... the "British Men of Letters"? Okay. Little weak, but okay. But when things get really bad, like the Apocalypse or the Other Apocalypse, that's when I have to step in.
Sam Winchester: So You're saying Jack is Apocalyptic?
