Which one of us is really the monster?

Dean

Dean: You know I hate shots.
Sam: I hate demons.

You got the stomach for that, Sam?

Dean

It's hell, you wait, it's what you do.

Crowley

I’m beat, man. One battle at a time. So I’m just gonna go grab my brother some cholesterol. And then I’m gonna get drunk.

Sam

Why can’t you people just sit on clouds and play harps like you’re supposed to?

Crowley

You don’t get to quit. We don’t get to quit in this family. This family is all we have ever had.

Sam

I’m loving the new model. Lean, mean Dean.

Dean

Dean, it's over.

Sam

I like the disease.

Dean
