Castiel, Dean and others in “Unfinished Business”

Castiel

I'm powerless.

Dean

You're joking.

Castiel

Something in this town is, uh... it's affecting me. I assume it's Eve.

Dean

So, wait. Mom's making you limp?

Castiel

Figuratively, yes.

Dean

How?

Castiel

I don't know, but she is.

Dean

Oh, well, that's great, 'cause without your power, you're basically just a baby in a trench coat. (Castiel looks away)

Sam

I think you hurt his feelings.
