Dolores Umbridge became the new Headmistress of Hogwarts, and patrols the school with Dementors and a revived Inquisitorial Squad led by Scorpius. Draco Malfoy occupies Harry's old position as the Head of Magical Law Enforcement, using his post to encourage routine attacks on Muggles and bribe the Prime Minister to remain silent on the actions of the Death Eaters. With help from Ron, Hermione, and Severus Snape, now the final members of a dwindling anti-Voldemort resistance movement, Scorpius is able to use the Time Turner to prevent the interference of Albus and his past self and restore the events of the original timeline, the alternate Ron, Hermione, and Snape sacrificing themselves to the Dementors in order to allow him to do so.
