Supernatural, Season 5

[Dean sees a person preaching on the sidewalk.]

Dean:
Hey, I'm Dean Winchester. Do you know who I am?

Preacher:
Dear God!

Dean:
I'll take that as a yes. Listen I need you to pray to your angel buddies and let 'em that I'm here. [The preacher starts to pray]

Castiel:
You pray too loud. [Cas touches the preacher, knocking him unconscious before grabbing Dean and slamming him up against a wall]

Dean:
What are you, crazy?

Castiel:
[punches Dean's face twice] I REBELLED FOR THIS?! [slams Dean into another wall and hits him a few more times] So you could surrender to them?!

Dean:
Cas... Please...

Castiel:
I gave everything for you! And this is what you give to me? [hits Dean again and kicks him into a fence, Dean falls to the ground]

Dean:
[looks at Cas, who's standing over him with his hands clenched into fists] Do it. Just do it. [Cas unclenches his hands and touches Dean's shoulder, knocking him unconscious]
