Dean, Ennis and others in “Unfinished Business”

Dean

[After decapitating a vampire] He looks better with a little off the top, don't you think? You want to run, now's the time.

I'm not going anywhere until someone tells me what the hell's going on.

Dean

You should go.

No.

Dean

All right, Sammy, give him the talk.

Sam

All right, look, my name is Sam Winchester. That's my brother Dean. We, uh... ...we kill vampires. And werewolves, and demons, and -- basically, we chase down evil... And we cut its head off.

So you're, what, monster cops?

Dean

Hunters.
