So I found out why I'm here and who set my house on fire.

I'm here because I'm stupid. I let myself be captured and they intend to use me to call The Boy, My Brother or The Angel. I don't think The Boy will come for me and I don't know why The Angel would be interested. Only My Brother might come and what will they do then?

As for the fire. It was set by one of the men with the triangle markings. 

Last question. Neither of these answer who cleaned up my house. There's someone else here I don't know yet.

I don't think I'll learn the answers before...

I feel Death coming quickly.
