Bill takes her hand in his, stroking her palm, turning the ring round and round on her finger, starting to see pieces of the picture. For a long moment he's silent; he knows that love doesn't come and go quite so easily. Not for him, and not for Fleur. For this to pain her so deeply...

"Of course. I loved you before, I love you now, I'll love you tomorrow. This must have been horrible for you: I'm sorry."

He swallows hard, though. He's not sure what she thought either, but... he knew about Ophelia. Perhaps he didn't have time to digest what that meant, but he knew. And he never asked Fleur to change, or to do anything differently, or to give anyone up on his behalf. She makes her own decisions.
