Bad Demon (Crowley/Aziraphale)
Sapphire_Swan
(set after the Apocalet'snot)
Crowley, in a fit of drunkenness, confesses his feelings for Aziraphale. It doesn't go down very well. In fact, it goes about as badly as it could've gone, and before Aziraphale could even try to process his (already given) response, Crowley is gone; vanished into thin air.
So, in a very Aziraphale-like manner, Aziraphale does nothing for a while, taking it all in.
And then he panics.
