Cedric nodded, slowly. "I can't imagine," he said softly. He really couldn't. Apart from grandparents, he'd never been touched by death. His parents were still alive, and healthy. Haley had faced a few small quidditch injuries, but nothing serious enough to make Cedric worry for her life. Even he, dangerous as his job could be, had been lucky enough that the worst he'd experienced was a week under a sleeping curse. Even his mother's cats, Huff and Puff, were still in good health. "It seems like this universe is better, and not just for selfish reasons." But was it really as easy as that? What if the war, whatever it had been caused by, hadn't been stopped but merely postponed? What if it was still inevitable?
He had no intention of demeaning Fleur's new relationship, so he paused to consider for a long time before he spoke again. "It's possible that you would... overlook more incompatibilities in wartime than you'd be willing to do in peace," he suggested. "I don't mean to suggest you're not well matched - you'd know better than I would - but... I wouldn't call it a guarantee." He placed a hand over Fleur's, giving it a squeeze to show he really meant neither offence nor harm.
"I'm sure the department of mysteries are working on 'how'," he said. He didn't, himself, care so much about that. "And I hope they're working on 'why' and 'who' as well. But even if they find out, that's no guarantee they'll tell us."
