There are many things that register fairly immediately when Sin wakes up every morning; whether or not she's in her apartment, if she's got someone with her, whether or not she's bleeding or about to be, and where her glasses are. She certainly remembers sleeping with Reno and being at his place, and so it doesn't shock her to wake up in unfamiliar surroundings this time, though she stays still and quiet for a minute before moving, feeling a warm male body at her back.

She yawns once, and is only mildly surprised to still have her piercings all filled after sleep. A lazy smile creeps up on her mouth as she remembers she was hardly in a mood to take them all out.

"Mmmmnf."
