Nabbing her blanket is an easy enough matter, she keeps pretty much everything within reach of the bed, just in case. A few flicks of the wrist get it unfolded and fluffed out, a warm wool blend that's cozy without being scratchy. Then she occupies herself with the far more important matter of sliding right up against him and pressing as close as possible. Kick him out of bed? Please, he'll be lucky if he gets a pass for dinner.

(She's still of half a mind to suggest a long shower, hot in more ways than one, but that might be a little like announcing to the household what's going on and that... there's no need.)
