Dean, Uriel and others in “Unfinished Business”

Dean

I want to talk to Cas alone.

Uriel

I think I'll go seek... revelation. We might have some further orders.

Dean

Well, get some doughnuts while you're out.

Uriel

[laughs] Ah, this one, just won't quit, will he? I think I'm starting to like you boy. [Uriel disappears]

Dean

You guys don't walk enough. You're gonna get flabby. You know, I'm starting to think Junkless has a better sense of humor than you do.

Castiel

Uriel's the funniest angel in the garrison. Ask anyone.

Dean

What's goin' on, Cas? Since when does Uriel put a leash on you?

Castiel

My superiors have begun to question my sympathies.

Dean

Your sympathies?

Castiel

I was getting too close to the humans in my charge: you. They feel I've begun to express emotions; doorways to doubt. This can impair my judgment.

Dean

Well, tell Uriel, or whoever, you do not want me doing this. Trust me.

Castiel

Want it, no. But I've been told we need it.

Dean

You ask me to open that door and walk through it, you will not like what walks back out.

Castiel

For what it's worth, I would give anything not to have you do this.
