"You want me to take you?" Hastur says, sounding incredulous. Perhaps the idea of self-sacrifice isn't something Hastur has ever considered. Perhaps the idea of sacrificing oneself for Crowley just sounds absurd.

Crowley, for his part, is trying desperately to get up. He doesn't have anything broken, but the throw has definitely knocked the wind out of him. He hears what Aziraphale offers, and he has to stop him. That stupid angel. Does he really think he can make a deal with a demon? Does he really think Crowley would want him to?

"Oh, very well," Hastur says, and far too easily. He offers out a grimy hand in the angel's direction. "Your life for the traitor's."

"Aziraphale, don't!" Crowley calls out, trying to get to his feet. He needs to---he has to do something---he has to figure it out, and fast.
