I think I agree on not having AA humans. But what if there is a Voldemort AA?! Though technically he's not human. He's immortal :sneaky:
Us - survive a Voldemort encounter? When Harry won't be there?
However, I do have to say it sort of sucks that we've had no sight of the villain in either part of the WW. Maybe this will change that, but I'm not counting on it. I think it's a pro and a con, on the one hand the suggestion of Voldemort is scary and you don't know where he could appear. On the other, he's the scariest thing in the world and we never encounter him...
