Lily's Son

Harry looks exactly like Lily when he appears at Hogwarts much to the surprise of everyone. What if Petunia told him about his world when he finally got his letter? What if they accepted him for who he was? Harry is sorted into Slytherin. He befriends Hermione (raven), Draco(Sly), Neville (Huffel) and of course Luna (Raven) later on. Whats a Potions Master to do? can he hate Harry?
