Rowena (to Charlie): You're young and good and I'm ancient and evil, is that it? Let me tell you about you. A difficult and lonely childhood, tragedy, absent parents, always outside the mainstream, sexually progressive, living in your own head for solace and direction.
Castiel (to Charlie and Rowena): It sounds like blood sugar is dipping in here. I got snacks. When I was human, I grew very fond of these pork rinds.
Rowena (to Charlie): That miraculous machine of yours hasn't solved everything by now? Overrated, I'd say.
Crowley: Just for once I wish you trolls would bring me some good news. 'Sire, Missouri has boils.' Something cheerful.
Sam Winchester: We're up against it. And we've all been up against it before and we know there are times when every choice sucks. Us lying to Dean is the choice that sucks the least.
Charlie Bradbury (to Rowena): I'm not a witch, I'm a nerd. And I know all the great centers of nerddom.
Dean Winchester (about Stynes): They screwed with financial markets, they helped Hitler get started along with God knows what else, probably disco.
Dean Winchester: You already got your revenge. If you go down this path, our path, it's not a long life.
Claire Novak: I don't know, you seem pretty old.
Claire Novak (to Sam): You said, sometimes death isn't always goodbye, right? So goodbyes aren't always forever.
Dean Winchester (to Claire): Your dad's sacrifice was not meaningless. Yeah, he gave up his body, his vessel, and because he did that, Cas was able to save the world. The world! Your father's a hero. He did not die in vain.
Sam Winchester (to Castiel): Here's all I know... Going it alone, that's no way to live. You being there for her, even if she thinks she doesn't want you to be there for her, that's good for both of you.
Dean Winchester: If we stay cooped up in this motel room all night long, I'm gonna lose my mind.
Claire Novak: Spoiler alert... You already have.
