When Harry's name comes out of the goblet no one believes him. After his friends turn their backs on him and his beloved owl gets hurt the young wizard unlocks a raw power he didn't know he possesed. Then when he least expects it he finds a kindred soul, who helps him. Who would have thought that Tom Marvolo Riddle could be kind too?
Purebloods test their children after they're born to see if they have a soul mate because soul mates can't kill each other and they for sure cannot be forced to fight to death. Magic will intervene and make sure they stop by any means. HP and LV/TMR are soul mates and they are forced to stop fighting because of a baby. Dumbledore, Molly, Ginny, Ron bashing. Naive Hermione.
