- Castiel: Dean, you two have been through so much. Look, you're brothers. It'd take a lot more than trying to kill Sam with a hammer to make him want to walk away.
- Dean Winchester: You realize how screwed up our lives are that that even makes sense.
- Castiel: You realize - one problem is solved, but one still remains. Dean is no longer a demon. That's true. But the Mark of Cain - that, he still has, and sooner or later, that's gonna be an issue.
- Sam Winchester: You know what, Cass? I'm beat, man. One battle at a time, you know? So I'm just gonna grab my brother some cholesterol. And then I'm gonna get drunk.
- Dean Winchester: Lemme ask you this, Sammy. If this doesn't work, we both know what you gotta do to me, right? You got the stomach for that, Sam?
- Dean Winchester: There's no point in trying to bring your brother back now.
- Sam Winchester: Oh, I *will* bring him back.
- Dean Winchester: In fact, your guilt-ridden, weight-of-the-world bro has been M.I.A. for quite some time now. But I'm loving the new model -- lean, mean Dean.
- Dean Winchester: You notice I tried to get as far away from you possible? Away from your whining, your complaining. I chose the King of Hell over you.
- [pause]
- Dean Winchester: Maybe I was just tired of babysitting you. Or always having to yank your lame ass out of the fire, since... forever. Or maybe -- maybe it was the fact that my mother would still be alive if it wasn't for you. That your very existence sucked the life out of my life.
- Sam Winchester: This isn't my brother talking.
- Dean Winchester: You never had a brother. Just an excuse for not manning up. But guess what. I quit.
- Sam Winchester: No. No you don't. You don't get to quit. We don't get to quit in this family. This family is all we've ever had!
- Dean Winchester: Well then we got nothin'.
- Sam Winchester: Would you say that to dad?
- Dean Winchester: Dad? Oh, there's a prize. Here's a man who brainwashed us into wasting our lives fighting his losing battle.
- [Sam stands]
- Dean Winchester: Oh. Ooh. Is this you manning up?
- Sam Winchester: This is me yanking your lame ass out of the fire.
- [Gives him another needle]
- Sam Winchester: You want me to debate you? This isn't even the real you I'm talking to.
- Dean Winchester: Oh it's the real me alright, the new real me, the me that sees things for what they really are
- Sam Winchester: What the hell are we doing to him, Cass? I mean, even after I gave him all that blood, he still said he didn't want to be cured, that he didn't want to be human.
- Castiel: Well... I see his point. You know, only humans can feel real joy, but... also such profound pain. This is easier.
- Demon #3: If you'll forgive my boldness... I could now be your wingman.
- Crowley: [Disdainful] Could you?
- Demon #3: I, too, love to party, and I do love the ladies and the classic rock 'n' roll. Most importantly, I can debauch by your side without being a personal embarrassment. You'll see what I'm worth.
- Crowley: Oh, I can see already.
- [Snaps fingers, the demon goes poof]
