Chuck: What kind of an ending is this?
Sam Winchester: His power. You sure it won't come back?
Jack: It's not his power anymore.
Sam Winchester: Then I think it's the ending where you're just like us and like all the other humans you forgot about.
Dean Winchester: It's the ending where you grow old, you get sick, and you just die.
Sam Winchester: And no one cares. And no one remembers you. You're just forgotten.
(Sam, Dean and Jack get into the Impala and drive away, leaving Chuck behind...)
Chuck: Guys... Guys... wait. Guys... Guys! No, wait. G-Guys... Guys, wait! Guys, wait! Guys, wait! Wait, wait, wait! Please wait! Guys!
(Jack takes away Chuck's powers...)
Chuck: This... This... This is why you're my favorites. You know, for the first time, I have no idea what happens next. Is this where you kill me? I mean, I could never think of an ending where I lose. But this, after everything that I've done to you... to die at the hands of Sam Winchester... Of Dean Winchester, the ultimate killer... It's kind of glorious.
Dean Winchester: Sorry, Chuck.
(Sam, Dean and Jack start to walk away from Chuck...)
Chuck: What? What?
Dean Winchester: See, that's not who I am. That's not who we are.
Chuck: You know, I tried and I tried and I tried, but you're all just too stupid, too stubborn. Too broken. You know what? I'm over it. I'm over you.
Sam Winchester: Yeah? Good.
Dean Winchester: Screw you, Chuck.
Chuck: No, screw you. You know what you do with broken toys? You throw them out. So, kill each other, don't kill each other... I don't care.
Castiel: What, you consumed your sister?
Chuck: We came to an understanding, so spare me your contempt, Castiel, the self-hating angel of Thursday. You know what every other version of you did after "gripping him tight and raising him from perdition?" They did what they were told. But not you! Not the "one off the line with a crack in his chassis."
(Dean aims his gun at Sam...)
Dean Winchester: Chuck has to die. He has to! Otherwise he'll keep us tap dancing forever, and I can't live like that, man! I can't live like that! I won't!
Sam Winchester: I know you feel like that right now, okay. I know you do. But you gotta trust me. My entire life, you've protected me... From Dad, from Lucifer, from everything. I didn't always like it, you know, but... it's the one thing in the whole world that I could always count on. It's the only thing I've ever known that was true. So please... put the gun away. Just put it away, and we'll figure it out, Dean, we'll find another way, you and me. We always do.
(Dean puts away his gun...)
Chuck: Are you kidding me?! After everything, all that, you... you did it again!
Chuck: I've made up my mind. We can go round and round, but you know me. In the end, I always get what I want.
Amara: What about what "I" want.
Chuck: Okay... what do you want?
Amara: Balance... something we've never tried before... Creation and destruction, light and dark, brother and sister united again, but on behalf of one world... This world. True balance. The way it was always meant to be.
Amara: But you can't. You only care about your pleasure. Your story. Well, I guess that makes you the villain.
Chuck: Villains get all the best lines.
Chuck: You don't understand.
Amara: Oh, I think I do. You want to evaporate every kernel of existence because the Winchesters won't do what you say.
Chuck: It's not about that. It's about everywhere I look, I'm reminded of my failures. Like, why did I go with carbon-based life? Why not silicon? Or yttrium? Zeroing out... starting fresh. That's what I need.
Amara: None of this was a failure... Not a tree, not a human...
Chuck: Humans! Humans are the worst. Lame, disappointing. They ruin everything they touch. And they're just so boring! I'm over them.
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.
