Jess can't tell if she's thrown him a lifeline or added more blood to the water and she's too tired to care. She would nod if she were still sitting up but now that she's lying down, she's planted, and any moving will become an ordeal unto itself. The windows and doors will probably stay open until she's so cold she can't sleep.

"Yeah," she says groggily, blinks and shutters her eyes. She expects he'll fuss a little more if he stays or shut the door behind him if he decides to go. Jess listens for either, or maybe the pitter patter of paws as he dashes out.
