That's a good point. I'm still not sold on the whole Harry as horcrux theory, though. I'd buy Snape's a super double-double secret agent before I'd believe Harry a horcrux. Although, anything is possible. But like others have said, why try and kill part of your own soul (as in Voldie repeatedly trying to kill Harry) then?
Perhaps he divided his soul too many times and needs part of it back to fully live? He did so want Harry to be there, and alive, at the end of GoF. Was his plan to recover his soul fragment as soon as he had a body again?
But I wonder if he became an accidental horcrux in Godrick's Hollow. Then DD showed up and removed the soul piece, creating the scar (like the crack in the horcrux ring.)
I'm currently rereading HBP so I'm obsessing over that ring!!!
Has anyone seen my kids!!! LOL
