The Marauders go into the future with Severus and what they see suprises them. They have to show Harry the truth. Lily is not his mother but Dumbledore put a glamour on him. Harry's real parents are James Potter who is actually Harry's mother and Severus Snape who is his father. (Male Wizards can have children.) They know because they met Tom Riddle who told them about it. They have to tell Harry the truth before Dumbledore kills him and gets all his money. But probably have to hide in glamour from Dumbledore and not tell Harry unless necessary. Read to find out. This is boyxboy. If you don't like don't read.
