This fits with chapters 3 and 4 of "Chocolate and Ginger".

Il faut que je t'aime

Iridescent

The sky behind the pyramids is a blaze of colour – purple and yellow, blue and orange. Fleur still can't quite believe that she is here, that Bill brought her to Egypt for a not-quite-Valentine's dinner. (Valentine's Day itself didn't happen for them.)

(Bill had to go away for the weekend – and of course he wouldn't – or couldn't - tell Fleur where or why. They argued, and she refused to let him kiss her when they parted. She spent half the weekend worrying that something awful would happen to him, and that the last conversation they would ever have had would be an argument.)

(Bill hated that he had to leave Fleur - Valentine's Day was important to her, even if it wasn't a big deal to him. He hated fighting with her. Most of all he hated that he couldn't tell her the complete truth.)

(Fleur made the best of a bad job, and went to the cinema with Gisela. They shared a takeaway and a bottle of wine afterwards, and had a thoroughly good time.)

(Bill spent the weekend spying on Death Eater meetings with Lupin and Tonks. It was cold and boring and frustrating. He missed Fleur horribly.)

So, two days late, they have their Valentine's dinner in a tiny restaurant in Egypt, overlooking the Nile and the pyramids where Bill used to work. Going back to reality in cold and foggy London is a wrench.

But Bill spends the night at Fleur's flat for the first time, and she has no doubts that she is doing the right thing. Her dreams as she sleeps in his arms are shot through with the colours of the Egyptian sky. This is the future she wants.
