And at Crowley's statement, he guides him forward, since he is an angel and he can cheat a little bit. He won't, because he'll want to feel a little bit of a burn, so that he can take the memory of this night with him with every step he takes. Maybe just a little bit.

He spreads his legs a little further, and tries to navigate Crowley through this mass of arms they're making.
