I'm reading the fourth book for the second time and I am confused about some things.
1. if Harry's mom was a witch, then why on pg. 646 does You-Know-Who say "A Muggle and a fool....very like your dear mother." was she a witch, and if so, why does He call her a Muggle?
2. if Tom Riddle and You-Know-Who are the same person, how is he alive today? I thought he was killed a long time ago when he was a child? AND if he was killed by Him, how is that possible- they are the SAME person?!
