one of them is the great snake thats with voldemort, nagi i think her name is. ( i personally dont think that shes one, and thought DD suggested her as one he never put all his faith behind it)
another one that being tossed around is the tiara that mrs wesley gave fluer decor for her wedding with charlie. i think its great aunt margi's teria or something. again the item is supposed to be goblin-made, and people think that it once belonged to ravenclaw. again i dont really see it.
another wierd theory i heard was that the award cup for magical merit to the school the one that riddle won while he was at hogwarts, thats another one thats being tossed around.
why thank you for the praise, maybe mention the theory on IMBD i wanna see if someone can poke holes in it, or if it really is that good. everyone i told it to has told me that si brillent. one last thing in there that i forgot to mention about it, think of the conflict that would cause harry, inorder to kill voldemort, he would have to distroy that which he loved the most, his only true home.
hey another thought i just had what if it wasnt the love that harry's mom wasnt what killed voldemort that day at goldrics hollow. what if what actually happened was that voldemort killed james, then tried to turn harry into a horcrux, but something happened, and for some reasons voldemort caste the spell, and nothing happened or something happened that wasnt supposed to, which made him think that his spell backfired, then un frustration he figured he should kill harry and because harry was a horcrux the spell backfired. i.e. what if the maker of a horcrux cant distroy one, and thats why the spell backfired, and thats why harry survived.
