"We're together, your mum and dad are alive, we can turn time Harry, we can't speed it up. She'll come when she's ready and we'll be ready for her."
-- Ginny Weasley (CC4.9)
31 October 1981
The wait for Delphi seems endless. Ginny realises that the reason Delphi has not already killed baby Harry is because she is waiting to meet her father Lord Voldemort and tell him about the original prophecy. If he is informed about what happens when the curse rebounds, the best way for him to avoid this will be by doing nothing to Harry (CC4.9).
All Hallows Eve - 31st October 1981
This event takes place during the Voldemort Final timeline, as described in the essay "Albus Potter and the lesson in Quantum Mechanics" by Nick Moline.
Ginny talks about how she felt after being possessed by Tom Riddle and how people reacted:
"After I came out of hospital - everyone ignored me, shut me out - other than.... the boy who had everything - who came across the Gryffindor common room and challenged me to a game of Exploding Snap. People think they know all there is to know about you, but the best bits of you are – have always been – heroic in really quiet ways." (CC4.9)
She says that Harry needs to be on that level with Albus - quietly loving and supportive (CC4.9).
