Sicily White is from Hogwarts in the 90’s. She goes to school with Harry and is the Slytherin alternative to him in every way. When Dumbledore decides he needs a backup plan to Harry and his team losing to Voldemort he decides to trust the only person he can with it. Sicily White, from an ancient and forgotten family, is a Slytherin, and a bloody good one at that. Dumbledore decides to send her back to the time where Tom Riddle was in school in his 6th year. He knows he has most likely made one or two horcruxes before but know that Sicily can change him. He truly believes that Sicily is Tom’s other half. But when Sicily gets there she is not so easily welcomed into Slytherin. Tom keeps her at a distance while his followers are ordered to get to know her, but she doesn’t let the pressure show, and sure enough Tom accepts her eventually.
