Aziraphale's response draws a relieved breath. It's not enough for Crowley to feel they're totally out of the woods yet, but a sense of impending doom that has loomed over him seems to be casting a much smaller shadow.

"Can I get you anything? Anything you'd like." he feels it's important to specify, the offer of course isn't just for things to aid in illness. 

It should be noted he hasn't tried to move yet. His voice remains soft, and his arms are loose enough around the angel that he could pull apart easily without effort, but their bodies close like this feels so nice; a luxury not often afforded.
