Wait, are you saying Harry Potter has books? I thought it was just a movie! ...Just kidding. I didn't remember because I've only read that book once, the day it came out, and have never really wanted to reread it. and you're right, but I think because he was under the imperius curse and he wasn't doing it of his own free will I wouldn't consider him one. I can't remember how he got out of Azkaban, was it a mass breakout?
