Lilly and James didnt die that fateful night but their souls just went to their original bodies they did, however, leaving behind their twin daughters Rosemary and Holly Petunia isn't spiteful Vernon is the same as he was in the book. Dudley is different he is still a bully but not towards his family and the twins count as family. Vernon is not actually Petunia's husband nor is he Dudley's father He himself believes that he is due to false memories that he gained after Petunia's mates disappeared. Tom Riddle isn't actually evil, He was ambitious, yes, He wanted to change the wizarding world yes, change the way all wizards and witches were treated and make the blood purity shit disappear as he saw how rare it was for purebloods to have magical children, ninety percent having been squibs,He wanted to bring the wizarding world to a new age Dumbledore doesn't want Tom's plans to come through and as Tom is beginning to start with his plans Dumbledore is lying in wake biding his time. He had blocked Lily Jay Potter's other mate links as well as James's other mate links on both sides. He had partially blocked James' link to Lilly so that it would seem like she was his only love.Fate and Destiny were not happy with Albus' plans and had come up with a plan to fight back unfortunately Fates magic didn't kick in soon enough it had kicked in as Lilly had taken her last breath. Albus made it possible for Tom's soul to split into five and placed four of the pieces into four special Items. Albus didn't however noticed that a piece went into the twin Potter daughters for a safe haven. What was left turned into a wraith, he was left a fracture of himself.Now the girls had a prophecy on their shoulders and they don't know the truth. They don't know that Voldemort is their mate and they are forced to fight him because the sliver of soul doesn't know the truth either. He believes in this fake prophecy.
