He hadn't been in a proper populated environment in many months, with the one exception being the sprawling Battle in his old school that had had him and his best mates literally running for their lives at points. Chaos like this, even when controlled and passed off as life, now left him feeling a palpable unease. He wondered if he had developed a fear of crowds, from all his months in near-isolation in the wilderness. If so, it wouldn't exactly be the worst phobia in the world to have – unlike, say, Ron's fear of spiders, claustrophobia could be grounded in something rational. Healthy, even, at least for a certain personality type. He would have to ask Hermione her opinion on the subject in a letter, or wait until she came back.
