I like it! Harry adding the oddities in his life together into a seemingly logical answer is a great twist. Magic still hasn't occurred to him, as most people see magic as stage tricks and, according to the authority figures in his life, 'real' magic does not, and cannot exist. On the other hand, there has been sufficient discussion on para-normal phenomena even then that might lead him to think he possessd some of those paranormal abilities, and more, can harness those abilities.
I have added this to my alerts list and hope to read more at your convenience. Alorkin
