Aziraphale and Crowley adopted you some time ago. You warmed up to them pretty quickly, and so did they.

It was winter, and a few days ago you sneaked out of the bookshop to play in the snow. Now you have a fever. Now that Crowley was away on "business," as he said, Aziraphale took care of you. You, on the other hand, as you lay on the couch under a blanket, thought of nothing but getting out and playing in the snow again.
