"I need to say sorry to you and sorry to Albus, will you give me that chance?"
-- Harry Potter (CC2.18)
When Ginny Weasley, her husband Harry and Draco Malfoy arrive in Headmistress McGonagall’s office by Floo Powder, wanting to see their children. McGonagall agrees as she sees that Harry has backed down from keeping Albus and Scorpius apart.
Around the same time as the previous event, September 2020
This event takes place during the Roseless timeline, as described in the essay "Albus Potter and the lesson in Quantum Mechanics" by Nick Moline.
When Hermione first mentions Moaning Myrtle, her bathroom is stated to be on the first floor (CS8). However, when Hermione again refers to Myrtle's place, she, Ron and Harry are investigating the flood outside the girls' bathroom on the second floor of Hogwarts. All the Polyjuice Potion-making and other action relating to the entrance to the Chamber of Secrets takes place on the second floor. Here, however, when Professor McGonagall shows them the Marauder's Map, Draco asks what Scorpius and Albus are doing in a first floor girls' bathroom (CC2.18).
