We are dealing with a sort of Hitchockian plot line, sort of like Spellbound. Bones is beset with nightmares which take place in the lab and she has ceases having restful sleep. Her nightmares are horrible. This is a continuation of the Puppeteer story. This has led her to see things that frighten because they involve people she knows. Mr. Bray is at the center of this but there is more to it than that. The story is well crafted to take us to the final season. A connection has been made with a psychologist that Brennan trusts. Brennan disappears at the end, but there is something about the way she confronts her, for us, unseen adversary. Wow!
