Greg thought Theo's twitch slightly endearing. He laid the wand down, the glow and warm air pointing to their feet, and he moved to place a hand on Theo's shoulder. He let his hand lie still for a moment, and then let it move up to rest at the back of Theo's head.
He didn't move for a long moment, and when he did, his fingers stroked the skin there, fingers wandering up into the hair at the base of Theo's head. Greg's eyes looked down, drifting closed every once in a while as he unconsciously shifted closer to the other boy.
