Ultimately there’s an echo of what Lily did, quite a conscience echo, right at the start of the story, at the very end of the story. At the start of the story Lily dies to keep her son alive. At the end of the story Harry lies to be pretending to be dead on the ground and it’s a mother who saves him again because she’s trying to get to her own son. That was closing a circle. He was saved by Lily and saved by Narcissa.
How adorable yet sad!
UNTIL THE VERY END
Albus: “Lily? After all those times?”
