"You saved my little girl, Melisande." It was all the explanation he felt it needed. An argument against her insistence he didn't like her. It was unorthodox that he attended these matters personally. Most of the times he did were a matter of PR.
The Sidhe weren't above that kind of thing. He stopped, hoping she might as well. But he was running out of ideas. Things might have to get messy one more time. "He can't get to my home, he can't even sift there. So he can't know those things. And why would he think you know who I am? You saw me once in the hospital, he might know that, but he can't have faked Andrew and me at the same time. Ask me anything you like."
They didn't have an extensive background. "You saved countless women by making him expose himself like this. We can stop him now. He could have kept killing for centuries before we noticed him if he hadn't taken you."
