Harry and Fleur had been dancing around each other for some time, but then their friends and family breathe out in relief as Fleur invites Harry on a date.
It all goes wrong when the date gets attacked by Death Eaters and Harry and Fleur vanish. The Death Eater involvement remains a secret. The Weasleys and Hermione suspect that Fleur kidnapped Harry, especially after Hermione finds out in a book that kidnapping your partner is an old tradition in Veela marriages.
Things are not helped by Fleur’s grandma Elena cheering that Fleur has “nabbed a good one”.
