Hart Hanson has said that the sex in the finale will not be a dream or a hallucination, but Emily keeps saying it's been done in a very "clever way" and Ausiello says he suspects it's a "dreamination". Is is happening for real,in real timE?

thats an interesting question and i think only Hart and Emily actually know the answer atm:) we have to wait till the finale to know how its gonna be...all you can rad are our predictions in the forum according to these spoilers...on the other hand theres no clear clue to know how exactly its gonna be:)

My guess from the promo videos is that we are going to find out at the end of episode that everything was Booth's dream during surgery. They are going to use fans response to this episode as how to proceed B&B relationship in next season.
