When the light hit Theo's eyes and he didn't react in more than his eyes Charlie frowned. Clearly he wasn't really awake or aware. Probably not awake actually, which probably explained the bare feet. And shit. He couldn't remember what the ideal thing to do with someone sleepwalking.
Then Theo turned his head from the light and Charlie thought he might be waking. "Theo," he said again, a bit louder, lowering his wand slightly to get the light out of his eyes. "Theo you need to wake up." He had the vague sense that touching someone sleepwalking might be a bad idea.
