Lucifer: Good try, Dean. I'll give you that, buddy. I'm not just powerful now. I am power. And I don't need a blade to end you, pal.

Sam Winchester: Dean! (Sam throws the archangel blade to Dean)

Lucifer: Bye-bye, Dean.

(Dean stabs Lucifer with it)

Jack: Is he...

Sam Winchester: He... he's dead.

Dean Winchester: Holy crap.

Sam Winchester: You did it.

Dean Winchester: No. No, we did it. We did it.
