Dean Winchester: You've gotta prepare yourself. I mean, this search could take a while. And all that anger... you can't keep it burning over the long haul. It's gonna kill you. You gotta have patience, man.
Sam Winchester: How do you do it? How does Dad do it?
Dean Winchester: Well, for one, them. I figure our family's so screwed to hell, maybe we can help some others. Makes things a little bit more bearable. I'll tell you what else helps. Killing as many evil sons of bitches as I possibly can.
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 is pointing the gun at Jack...)
Sam Winchester (to Chuck): Do something. (realization shows up on his face) You're enjoying this.
Sam Winchester: Do you watch us? When you're not here, are... are you... watching us?
Chuck: Yeah. I mean, you're my favorite show.
Sam Winchester: How many are there... how many other worlds or... or universes or realities or whatever?
Chuck: I don't know. Kinda lost count. Most of them are boring. One's in reverse. In one, there's no yellow. One... One of them's just all squirrels.
Sam Winchester (to Dean): I'm the one who brought him back, and I brought him back because he's family. And then he came back, and he burned his soul off to save us... you and me. And now what? You... Now you... you want my permission? You want me to say I'm cool with losing him and losing you all at once? 'Cause I can't do that. I won't say that, 'cause I... No. I've already lost too much.
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?
Dean Winchester: When people can't lie, the Internet gets real quiet. Yeah, guess your life isn't so perfect after all, EightPackMommy.
Sam Winchester: What?
Dean Winchester: Yeah, she's got this blog. Yeah, you know what? Your kids aren't that cute. And that gluten-free popover looks like crap because there's no gluten in it. You know what I mean? I'll stop talking.
Dean Winchester: Tell me who your favorite singer is.
Sam Winchester: What?
Dean Winchester: You... Look, I know you say it's Elvis, but we both know that's crap, so tell me who your favorite singer is.
Sam Winchester: Well, it's like you said. It's Celine Dion. Uh... I mean Celine Dion. It's Celi... Dean, every time I try and say "Elvis," it comes out...
Dean Winchester: The sad, horrible truth.
Dean Winchester: Nerds.
Sam Winchester: Takes one to know one.
Dean Winchester: What?
Sam Winchester: You. Come on, man. You're always calling me a geek, but you know every word to every Led Zeppelin song... backwards and forwards... you can discuss in detail every major rock drummer between '67 and '84, and... you watch "Jeopardy!" every night.
