Hmm, it's interesting to see a rather more observant and aware Harry start to put the pieces together early. I like the fact that he's already doing apparition as well as the direct wandless, and wordless, equivalent of /Alhombra/. If he works on developing this ability, he's going to be quite a shock to Hogwarts when he arrives. Depending on how you portray Dumbles, this could be seen as a good thing or a bad thing.
