Bobby, Castiel and others in “Unfinished Business”

Bobby

You're telling me you lost your mojo just in time to get me stuck in this trap the rest of my life?!

Castiel

I'm sorry.

Bobby

Shove it up your ass.

Dean

[quietly, to Sam] Well, at least he's talking now.

Bobby

I heard that.

Castiel

I don't have much time; we need to talk.

Dean

Okay.

Castiel

Your plan. "Kill Lucifer."

Dean

Yeah, you wanna help?

Castiel

No. It's foolish, it can't be done.

Dean

Oh, well, thanks for the support.
