Prompt:

What happens if Snape wouldn't have told Voldemort about the Prophecy he overhears Prof. Trelawney tell Dumbledore? What happens if Dumbledore had taken action after finding out both the Potters and Longbottoms were expecting babies born at the end of July? Dumbledore is present when the secret keeper charm is cast, therefore there's no switcheroo with Pettigrew and Black. It's a normal life for both the Potters and the Longbottoms. Harry and Neville don't have to suffer the consequences of being orphaned. Bellatrix never tortured Frank and Alice to the point of insanity. Harry can have the family he never got to experience in the books. The only thing standing in the way of the world being perfect is the ever looming threat of Voldemort, except there are four more people to help fight the Dark Lord. Do Harry, Ron and Hermione still meet on the train, and do the three of them marry their respective spouses in the epilogue? Is the Golden Trio forced to grow up faster because of the greater threat of Voldemort and his pure blood nonsense, or are they left completely out of the loop and the grown ups get to deal with him this time? Does Snape stay bad because there's no deal with Dumbledore to protect Lily?
