Season 3, Episode 9
Dean and Sam find out some about Ruby's human life while facing off against a coven of witches.
Dean: I hate witches. They're always spewing their bodily fluids everywhere. It's creepy, you know. It's down right unsanitary.
Dean: Why's the rabbit always get screwed in the deal?
Dean: I mean, this doesn't exactly look like the tv room of a bright and stable person, you know.
Ruby: Put a leash on your brother, Sam, if you want to keep him.
Sam: Wait, so you're mad because I'm starting to agree with you?
Dean: I'm not mad. I'm worried, Sam. I'm worried 'cause you're not acting like yourself.
Sam: Yeah, you're right. I'm not. I don't have a choice.
Dean: What's that supposed to mean?
Sam: Look, Dean, you're leaving, right? And I got to stay here in this craphole of a world alone. So the way I see it, if I'm going to make it if I'm going to fight this war after you're gone then I gotta change.
Dean: Change into what?
Sam: Into you. I gotta be more like you.
Tammi Demon: Nice dick work, Magnum.
Tammi Demon: No, but I'm wearing her meat.
Ruby: That's what happens when you go to hell, Dean. That's what hell is, forgetting what you are.
Ruby: You need to help me get him ready for life without you, to fight this war on his own.
