yeah he is powerfull, but if i recall correctly, he just said that he was gonna leave school, i can't remember if he did or not. and i to would like to know who the heck R.A.B. is, and i think that harry himself might be a horcrux, and he will have to die in order for the horcrux to be destroyed, therefore, he would still die but he would have taken out voldemort with him.
