“The one with the power to vanquish the Dark Lord approaches… born to those who have thrice defied him, born as the seventh month dies… and the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not… and either must die at the hand of the other for neither can live while the other survives… the one with the power to vanquish the Dark Lord will be born as the seventh month dies….”
Voldemort heard a part of this prophecy and realized that it meant Harry or Neville, but why choose Harry? Do you think he would’ve gone and killed Neville as well had his plan worked? Dumbledore mentions that Voldemort chose the half-blood over the pure blood but that seems very uncharacteristic of him do, even with him being a half blood.
