Worse than usual isn't a... brilliant thing for Aziraphale to say. Crowley tucks Aziraphale closer into his body, as much as he can. Aziraphale has become so much bigger than him now that it's much more difficult to play the role of comforter.

He shifts to toe off his house shoes and climb onto the bed properly, pulling Aziraphale against himself.

"Nowhere else for me to be, angel. I want to be with you."

He's said this before, in different ways, but it always bears repeating. Crowley might, in theory, be safer somewhere else. He might be better off staying in another room away from Aziraphale until this all passes.

He doesn't want to do that.

He drops his face, instead, to press into a warm patch of Aziraphale's mane and holds him a little tighter.

"Besides, you're keeping me nice and warm like this."

Snakes like heat. Crowley does hate to be cold, even if it isn't particularly cold today. It's a good excuse.
