Hermione holds another meeting in the grand meeting room, informing the attendees about Delphini’s existence and their inability to apprehend her, as she is hiding in time. McGonagall is upset with Hermione for keeping the Time-Turner, but Harry, Ginny, Draco, and Ron defend Hermione and share accountability for Delphini having gotten hold of the Time-Turner. The Ministry is doing its best to gather information about Delphini; meanwhile, they must wait for Delphini to either fail or succeed in her attempts to change history.

At a train station in the Scottish Highlands, Albus and Scorpius deliberate talking to the station master to gather more intel about “when” they are. They have a confusing conversation with him but based on the date mentioned on a timetable he hands them, Albus divines where Delphini is and why—it is the eve of Halloween in 1981, the day before Harry’s parents were killed by Voldemort; Delphini is trying to break the original prophecy which foretold Voldemort’s downfall when he attempts to kill an infant Harry, by killing Harry herself.
