After the Mares and having so many days of being entirely unable to sleep, when Faith finally can again she's savoring that shit. So when the light peaks into the window Faith growls at it- a low rumbling sound, "Nghh.."

Turning around, she burrows her face into the owner of the bed's chest to fight off waking. This kind of thing is easier now. Spending the night is very much unlike Faith. She hadn't used to stay long after they screwed, afraid of what staying might mean. But Klaus made it easy, somehow.
