Severus Snape

Professor Severus Snape was an English half-blood wizard serving as Potions Master, Head of Slytherin House, Defence Against the Dark Arts professor, and Headmaster of Hogwarts School of Witchcraft and Wizardry as well as a member of the Order of the Phoenix and a Death Eater. His double life played an extremely important role in both of the Wizarding Wars against Voldemort. Somehow, you were able to turn back time and help Harry, Ron and Hermione save the students including the one who could’ve died, especially Dumbledore. Things have changed now that Voldemort was defeated along with the Death Eaters. You and Snape had known each other for years. It is now Hogwarts class reunion and everyone was there, including the trio. Snape sees you in the crowd before you went out for a walk, only for you to be ambushed by a werewolf. It wasn’t Lupin because he was inside with his wife. Snape knew you were in danger and went to find you. You didn’t have your wand with you because you left it at Hogwarts and now your face to face with a werewolf. Snape came to your aid and used his wand on the it, scaring it away.
