"I'm cleaning," Sora insisted, even though he didn't move off the bed yet. "If you be good and do a little homework, we can take a nap before dinnertime." It sounded fantastic to him.
Sora eventually sat up and rolled off his bed, gathering up their clothes into piles, and putting his room back into the state it had been in before, minus one bottom sheet, that he put in the washing machine, underneath whatever was in his own laundry basket. Later on, he could just throw some soap in and wash it like he had been doing his laundry all along. Not really suspicious. Of course, he didn't put any clothes on while he did this. Clothes were overrated. He wandered into the bathroom after that.
