Fletcher smiled a little at the sound of bones breaking. He closed his eyes to take in the sound of the man's screaming. He could never quite get enough of it. He knew people didn't always like so much...noise, but it would hardly be as exciting to him if the person he was going after didn't scream and get worried about things.
He glanced over at the sound of Draco's question. "From what Pansy said, it does. We're going to have to figure out somehow if people are coming off the potion." He let out a sigh. "As much as I hate to say so, I think we're going to have to prepare for it getting a little more widespread. If there are those out there off the potion already, then they are likely to be helping those of the people they are close with."
"Ella's brother first, now Pansy. I don't know who is next, but I'm suggesting that we make sure those who matter to us are taken care of." He flicked his wand, smiling a little as the man started struggling to breathe. A few more moments and he let up. Couldn't kill him yet, of course.
