Summary
Analysis
On top of the train, the wind howls around Albus and Scorpius. Albus calculates that if they jump off soon, it won’t be far to St. Oswald’s Home for Old Witches and Wizards. Suddenly, they see the trolley witch selling her snacks on the top of the train. She explains that it’s her job to make sure no one gets off the train before it reaches its destination. Her hands transfigure into claws and she lobs exploding candies at them. Desperate, Albus casts a Cushioning Charm and jumps off the train. Eyeing the trolley witch in fear, Scorpius jumps after his friend.
As Albus and Scorpius start to face dangerous obstacles like the trolley witch, they show how much they are willing to sacrifice their own well-being in order to do what they think is right and remedy Cedric’s unjust murder. And, in addition, they are able to do it because they have each other supporting them, as Scorpius comes along both to help Albus, and also because Albus’s bravery makes him want to do the right thing as well.
