"Have you heard the rumours? Big Ministry raid a few days ago. Your dad apparently was incredibly brave."
-- Rose Granger-Weasley (CC1.10)
Rose Granger-Weasley asks Albus Potter whether he has heard about the Ministry’s raid that confiscated an illegal Time-Turner. Having recently listened to his father and Amos Diggory’s conversation, this gives Albus an idea of how to save Cedric Diggory.
He meets with Scorpius Malfoy on the Hogwarts Express and says that they need to get off the train (CC1.10).
