Derek nodded a little, letting Stiles take the book back and dropping his hands to his lap. He watched him take two steps back and looked up when he cleared his throat. He wasn't sure why everything felt tense for those few moments but it was dissipating and he relaxed at the distance put between them, reaching for the bottle of water he'd had to finish it. Stiles made his decision on what they should do and Derek nodded again.
"Okay, sure," he agreed, settling back against his bed, lying sideways across it, his feet on the floor. He tucked his arms under his head, trying to find something to think about besides reciting Siken poems in his head over and over until the words made some kind of sense to him. He was still adjusting to everything with a new moon to react to and a the weird dampening of his abilities but he was trying not to think about that either.
He waited for Stiles to finish the book, and let his eyes slip shut, his breathing evening out for a while. He wasn't asleep but he felt like he could probably sleep better now if he'd tried, but they were going out soon and he was going to have to lift things so sleeping was out of the question.
