Out came the truth so it seemed, Aniel stood, slightly shocked at her sudden confession, but quickly put himself back together, now he really had to think of a plan. She clearly needed to know about this beast and kill it herself, it killed him to know who the beast was, but that was better than her killing him if she found out.
So she has been doing this all to protect family then hm? That was as good a reason as any it would seem, he would have done anything to protect his siblings if he had any. But she did not know what Aniel would never kill her brothers, even should he get the chance. Unless they where against society. It seemed however that whatever news did get to the public did not include that detail, the fact that only criminals have been killed.
"Listen, I can not help your brothers, and I can not help you, all the information I have on the case stays with me. If you really need to help, what you can do is try and get your brothers to stop their hunt for this beast, we still don't even know what kind of were-beast it is."
