Am I tainted by the movie or is Flitwick not a human? If so, he was a 
student at Hogwarts at one point (he's the head of his house) -- so 
where are the other non-human students at Hogwarts? I know there has 
been guessing about some students being part-something, none of them 
are as outwardly something-else like Flitwick. Thoughts?
