Sam Winchester: There's gotta be something, some way. Whatever it is, I'll do it. Don't, Dean. I'm not gonna let you go to hell.

Dean Winchester: Yes, you are! Yes, you are. I'm sorry. I mean, this was all my fault. I know that. But what you're doing is not gonna save me. It's only gonna kill you.

Sam Winchester: Then what am I supposed to do?

Dean Winchester: Keep fighting. Take care of my wheels. Sam, remember what Dad taught you. Okay? And remember what I taught you.
