Who is this?

I’ve told you about Penrich. The truth is even stranger; he woke me up in the middle of the night, forcing things into my head, strange thoughts, I s’pose you could call them thoughts. I couldn’t sleep after that, then I knew I had to do something about it. Why fight him, when I want to be like him? Perhaps I will let him into my life, slowly (I don’t want him to get too bigheaded).
