Fred let out a weighted sigh. He'd been right, then, about what was upsetting her. Vaguely right, anyway. Part of him hated that she was going through this, but the other part was glad that she was at least beginning to put her thoughts together the way the mass majority of the population could no longer seem to do. "Yes, I knew that. I didn't think it would accomplish anything to alarm you, though, so I kept it to myself." He wondered if she knew John was Remus, too. "I would have known it was you even if I hadn't know it couldn't be whom the Prophet said it was," he said and then added, belatedly, "We wolves all have distinct differences when we transform, Monty. What happened that night?"
Fred frowned, rubbing his hand consolingly, comfortingly over her arm as he spoke. If she was making any progress in fighting that sodding potion, he almost wanted to push it, to try and help her get through it so that she wouldn't have to go through it again. It wasn't really his choice to make, though, whether she preferred the potion or the knowledge that her world was not right. That didn't mean he couldn't try to give her the pieces of the puzzle--without condemning himself--and let her mind decide if it wanted to piece it together.
But then she mentioned Fenrir and Fred let his own emotions get the better of him. "There is another distinct difference between wolves like us and wolves like Fenrir. We transform because we have to, we take Wolfsbane because we refuse to lose our heads in the process. We've seen, firsthand, what he chooses to do." Remus, Aldous, Fred; those were all prime examples of how much Fenrir did not care about the ramifications of his actions, took pleasure in them, even. "One has to wonder why a wolf like us is wanted for execution and a wolf like him is allowed to run freely with the support of our great Minister." He was going too far, he knew it. He was putting her thoughts on the line, putting his life on the line, considering her sister was one of the people who was making this world as terrible as it was.
"One also has to wonder why someone is using your photo to pretend like they have apprehended a man who is very much not in their possession." He was saying far too much, but he couldn't help himself. This business with Fenrir, with Remus, it was all too personal to him.
