XD You know when you look up something and it shows a bunch of pictures, well, I typed in my username, shortcrazygirl and what do I find? lol One of the pictures I found was Ravenclaw's diadem. lol so that makes me the heir or Ravenclaw XD.
Watch out, Voldemort. You have someone else to contend with.
