"I'd offer to take 'em for good, but that's a bit beyond me right now." He's already mentioned Satan, and this guy is off his rocker enough that if he started accusing Crowley of being Not Human, he's pretty sure he could talk his way around it.

So what does it matter, admitting one little thing?

At the actual question, he does look down at his hand; it's mostly stopped bleeding, none of the cuts really deep enough to do serious damage. He idly wonders if it'll scar. He's never had scars before, not physical ones. "Nah, hurt myself on one of those blessed bulbs. I think I'll live."

The sarcasm probably isn't necessary.
