Harry is organising a Halloween sleepover for Teddy, Bill asks him if he can slot in Victorie since he's supposed to be taking care of her for the day but there was an emergency at work (divorce with shared custody, Fleur is doing some Veela stuff on (insert old name for Halloween I can't remember ) ). Harry agrees, the more the merrier. The next morning, he's entertaining the children again, Fleur shows up joins the fun. The thing quickly turns from "entertaining children" to some competition (memory showdown, water fight, Jenga).
Andromeda shows up and watches the domestic scene. Given how well they get along, Andromeda congratulates them on their relationship, leaving them stuttering denial. Andromeda picks up Teddy and leaves, afterwards Fleur and Harry have a talk about maybe trying the whole relationship since Andromeda had a point, they got along splendidly and enjoyed each others company
