Jack Kline: What's that?
Jack Kline: I like The Who.
Max: My aunt listens to them. They're... old.
Jack Kline: Well, Dean says any music made after 1979 "sucks ass."
Max: That's because Dean is also old.
Jack Kline: I like books, too. I'm reading about zombies.
Eliot: Zombies are real?
Jack Kline: Well, no. Not really. It's kind of disappointing.
Eliot: You live with Sam and Dean, right? They're not here right now. Are they fighting ghosts?!
Jack Kline: What's a ghost? I should go.
Max: Hey, it's... cool. We know. About their whole Hunter thing.
Jack Kline: Oh. Good. I don't like to lie. It makes my stomach hurt. Like when you have to burp, but you can't burp... Yeah.
Jack Kline: When it was gone, how did you... how'd you feel?
Donatello Redfield: Like... the galaxy. You know, Jack, our galaxy's all bright and shiny and spinny, but in its center lies this very large black hole. It's the same with me. I'm all bright and shiny, obviously... Not so much spinny. But inside? Empty.
Jack Kline: So you feel bad?
Donatello Redfield: I feel... nothing. Losing your soul doesn't make you bad. It doesn't make you anything. It's, um... an absence of... of pity, of empathy... of humanity. How do you feel, Jack?
Jack Kline: I don't know. I know I don't feel...nothing, but I don't feel the same, either. And maybe I just don't know what nothing feels like.
Jack Kline: I'm trying different foods for the snake.
Dean Winchester: Why?
Jack Kline: I think he's sad.
Dean Winchester: Oh. Have you tried bacon?
Jack Kline: Do snakes like bacon?
Dean Winchester: I don't know. I like bacon.
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.
Sam Winchester: Maggie says decapitation is the only way to kill these things.
Dean Winchester: But if we cut off their head, then is more creatures gonna crawl out?
Jack Kline: Wait. Other creatures?
Sam Winchester: H-He's talking about "Clash of the Titans" again.
Dean Winchester: We don't know...
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.
Jack: You don't know anything about Dean.
Michael: I'm in his head... literally. I know everything. Like, I know how sad he was when you died... on the outside. On the inside, well, it's not that he was happy... he just didn't care. 'Cause you're not Sam. You're not Cas. You're a new burden that he was handed. You're a weak, helpless thing. You think that they care about you, love you? You're a job, a job none of them wanted.
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."
