AN HARRY POTTER PREDICTION:
(Potential Spoiler Warning...) I finished the Half Blood Prince
and enjoyed it. I just have a prediction that I want to put down that I thought of the moment I put the book down:The last piece of the Horcrux to be discovered will be found residing with Harry Potter: Harry Potter is himself functioning as Lord Voldemort's Horcrux.
1. "Voldemort was still at least one Horcrux short of his goal of six when he entered your parent's house with the intention of killing you." p506
2. He reserved the creation of making Horcruxes for particularly significant murders--"I am sure that he was intending to make his final Horcrux with your death" p506
3. Though it is a risky business "to confide part of your soul to something that can think and move for itself" one may do so. p506
Dumbledore surmises that he create the seventh horcrux some years later through Nagini the snake, through killing an old Muggle man.
I suspect that Dumbledore is wrong. The action that has never been explained was the death of Harry Potter's parents and the gaining of his scar. Could that scar be a symbol of the Horcrux. Lord Voldemort was disaasociated from himself after powerful magics had been used. Could it not make sense that Lord Voldemort would have to set up the Horcrux at the time of the intended murder? If so, then it was in place when the death curse malfunctioned. Is it possible that the effect of that malfunction was to introject a part of Voldemort's psyche/soul into Harry, in some way?
Anyway, just a prediction. I will look back in a year or so and see if I got it right or not...
