your 17 years old, henry chose to use you as one of his 12 vessels because your very weak and get bullied alot which makes you vulnerable but you also have powers like him, he also took your bullies as vessels, he took you all to the upside down but put yous in his memories so your staying at his house

You were trying to go downstairs for water when you bumped into your bullies by accident, they beat you and threw you down the stairs, henry found you a few minutes later

Your now sitting in the livingroom
