House barks out a laugh. He knows he's aiming low, but when had that ever stopped him in the past?
"But he's you, isn't he?" He looks over his shoulder at Castiel's silently seething expression. "I wonder if he has the same thoughts about you - can't stand the disgusting idea of being an angel again! Bet you're a disease to him, just like he is to you."
House tsks. He feels his pager goes off, and there's a moment where he completely stops, thinking of the trouble Psycho-bitch's vessel could be making, or worse off, the demon within, but he doesn't check it quite yet.
"Go on, scram. You could at least be trying to find a way to get rid of him, while I'm stuck trying to hold this whole damn hospital together!"
