Severus Snape, caught up in the past, makes a horrible mistake while working on a potion meant to defeat Death Eaters by de-aging them until they disappear. He adds a couple of wrong ingredients and spills the potion on himself, and is de-aged to a sixteen-year-old's body. Headmaster Dumbledore asks him to go undercover as a Gryffindor student in order to get close to Harry Potter, who is avoiding all of the Order members.
