Supernatural, Season 4

Chuck:
You... you're Castiel. Aren't you?

Castiel:
It's an honor to meet you, Chuck. I admire your work.

Dean:
Whoa whoa whoa. What, this guy, a prophet? Come on! He's practically a penthouse forum writer! (to Chuck) Did you know about this?

Chuck:
I uh - I might have dreamt about it.

Dean:
And you didn't tell us?

Chuck:
It was too preposterous. Not to mention arrogant; I mean writing yourself into the story is one thing, but as a prophet? That's like M. Night-level douchiness.

Dean:
(to Castiel) This is the guy who decides our fate?

Castiel:
He isn't deciding anything. He's a mouthpiece, a conduit for the inspired word.

Dean:
The word? The word of God? What, like the New New Testament?

Castiel:
One day, these books, they'll be known as the Winchester Gospel.

Dean & Chuck:
You gotta be kidding me.
