Castiel: The Occultum is divine in its origin. It was housed for hundreds of years in an ancient temple before it was...
Dean Winchester: Plundered by pirates.
Dean Winchester: It was dug up by tomb raiders.
Dean Winchester: It was seized by the King of the Dead and his warlords. Am I close?
Castiel: Looted by invading Mongol hordes for trade on the...
Dean Winchester: Black market. Yeah, that's what... I was gonna say that next. That was the next one.
Castiel: You know, Michael, I never really liked you. Even when I was just another angel, I thought you were too haughty, too... To paraphrase a friend, you had an entire oak tree shoved up your ***. But now? I'm looking at you, and I...I just pity you. Because you were never God's favorite. You were just a little part of his story, a tiny part of his story. You weren't even a star. At least Lucifer knew that God can't be trusted. But I guess he was always the smart one.
Rowena: What am I picking up from you two? A wee tiff? Tell your Auntie Rowena.
Dean Winchester: It's fine. Don't worry about it.
Castiel: It's fine.
Rowena: Boys? Fix it. I don't have many regrets, but the few I do still haunt me. Making Napoleon so short was just bitchy. Telling Mick Jagger he had no future when I dumped him. And, well, everything with dear Fergus. Then one day, you die, you go to hell, they make you queen, and... you can't make it right. So fix it!
Belphegor: Shouldn't we at least try and be friends? Sam and Dean, they seem to be coming around. I think I'm, uh, growing on them. You know, like a cancer.
Castiel: You are not growing on anyone. Sam and Dean are just using you. Don't mistake that for caring about you, because I can assure you they don't.
Belphegor: Wow. You learn that the hard way?
Castiel (to Dean): Even if we didn't know that all of the challenges that we face were born of Chuck's machinations, how would we describe it all? We'd call it "life". Because that's precisely what life is. It's an obstacle course, and maybe Chuck designed the obstacles, but we ran our own race. We made our own moves. And mostly, we did well with that.
(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?
Castiel: You should never have tried to lock him away.
Dean Winchester: You know what? You're right. I never wanted to put him in that damn box. I wanted him dead.
Dean Winchester: He's dangerous, Cas, and you knew it! You've known it for a long time! But that's okay. You know why? Because me and Sam, we've killed just about everything there is. And this... Jack... oh, we'll find a way. Because he's just another monster.
