Theo wasn't used to such a reasonable attitude towards things that didn't really matter, especially not in his current mindset, and Charlie's ease with his actions in turn put Theo a little more at ease. He didn't even realise that Charlie was moving around him with such care but he did notice how much more comfortable he felt in Charlie's presence, even if he didn't know why. He was very awkward about letting someone else tend to him like this, or show him any care, and the unusual situation seemed to have him hold his tongue.
Nothing could stem his curiousity though, though his father had tried his best to do so, and Theo watched attentively while Charlie sorted through the first-aid kit. He looked through the selection of healing things and shook his head. "No allergies. I've used all of these before, they're all okay." he confirmed with a slightly shy smile of reassurance. "Thanks for doing this." he said again, like his gratitude was all mixed up with his surprise and kept leaking out now that his defenses were lowered by his previous sonambulism. It was clear that he had no idea what to do in this situation.
