What's in Room 11 (Doctor Who's Biggest Unsolved Mystery)

In the Doctor Who episode 'The God Complex', the Doctor opens the door to the mysterious Room 11 and looks inside. However, while the Doctor does see it's occupant, we the audience do not. An explanation was provided a couple of years after transmission but I am not satisfied with it and so in this video, I set out to provide my own explanation... for what's inside... Room 11.
Hope you enjoy the video!
