After overhearing Harry refuse to help the Diggorys, Albus is inspired to do so himself, and convinces Scorpius to help him. The two escape from the Hogwarts Express and the trolley operator, who is revealed to be a monster placed on the train to prevent students from escaping. The two arrive at St. Oswald's Home for Old Witches and Wizards in Yorkshire, where Amos lives, and team up with Delphi to steal the Time Turner from Hermione's office while disguised with Polyjuice Potion.
