"And I'd like to offer the same to you, Fleur. I have...connections. They're not always the best, and I'm afraid I've been cast out of the loop on some of the more important matters, but on occasion, I receive updates before everyone else does. I'm not sure it would be wise to pass information by owl, but if it's vague, it shouldn't be too much trouble. And Penny, Penny..."
He trailed off, wondering if he hadn't said too much, but Fleur didn't know Penny, or her situation. Still, his cheeks flushed a little. "Penny bought me one of Fred and George's journals," he finally said. "So we can communicate."
