Derek had just rolled his eyes horribly at him, because really, this kid. This. Kid. Sighing to himself, he'd settled down more and eventually was out cold. He wormed his way around the bed, uncomfortable and unsettled the entire time, and he knew subconsciously it was because so many bad things had happened in this room, some of them on this very bed, and he wasn't yet used to the place being home again. He'd needed to get away and the few weeks dicking around in an alien planet didn't count properly.
It was a little longer before Derek just woke up by himself, sucking in a sudden breath and blinking at the light coming through the window like it personally offended him. He groaned roughly and rolled over, only then realising Stiles was in the room still. He watched him for a moment before huffing at him for no reason whatsoever and pulling a pillow over his head, intent on going right back to sleep.
He didn't like anything about his bed at the moment. The sheets had been changed after Cora had sweated right through them while dying, but the smell of his sister's illness hung in the air, and even the scent of Jennifer's perfume lingered a little, so he wriggled further away from the side of the bed he was on, towards the other side, the pillow abandoned by the time he made it to the middle of the bed, sprawled half on his stomach and half on his side, one leg pulled up a bit and arms folded under his head.
