The fact that he's begun seeing a therapist regularly implies to me that he's from this side, yes. He's also around too much to be on the other side. I could be wrong, but if he was from the other side, what reason would he have to worry about being caught or hurt by me?
My family has never been particularly close. We were as children, but we all lived out own lives and moved away from one another. Then, when I was older and [...] discovered that I was adopted, that I had a family I'd never met, it felt a bit like a clean slate, to try to connect better. I like Sam a great deal, though I don't really know how she feels about me. Regardless, I want the best for her. I don't want this psychopath to have a chance to touch her again.
Honestly, I don't know. I know what her injuries were, and I know the person that caused them was male because of what Sam has said. I know he is one of us, which narrows the field of suspects a great deal. Aside from that, though [...] perhaps I shouldn't have said anything. I'm beginning to feel a bit as if I'm facing a brick wall. I have nothing to go on, and the Anonymous man has made it clear he intends to give me nothing. My sister won't cooperate to give me enough information to track him down.
Truthfully, I'd appreciate it if you could simply check on her well being. I think she could use someone to talk to who she doesn't suspect of writing the message seeking her attacker, and who doesn't know the grisly details as I do. The comment she left for the man was public, making it clear she was the person being talked about in the message from me that came before his. Perhaps you could contact her about that? And then if she happens to say anything telling, you could pass it on. If she does, wonderful. If not, she'll have someone else to talk to about this.
I don't mean to foist her on you or anything of that nature. If I thought she would talk to me, I would do this myself.
