Remus listened, mulling over things in his head, something about the sheer randomness of the events nagging at him. "You know, even if it is a person, they might not know they're doing it," he said slowly, his thoughts on Cymbeline and the things that had occurred when she had been quite small. "What if it's a powerful person, a child, perhaps, or even someone who is mad, who is causing this without realizing it? It all seems just so unfocussed and without reason, it just doesn't feel like there is any coherent thought behind it. I would suggest checking out the psychiatric ward at St. Mungo's, and if that falls short, starting on Muggle hospitals. Children would be a bit more problematic, of course, unless there was a sudden surge at Hogwarts."
