Who is the mystery man at 0.36 in the trailer for "Death In Heaven" what is the significance to him in the trailer when we don't know him? Green uniform and lots of notes behind him pinned on the board. Face in complete shadow.

A surgeon?

It's either Romana or The Rani. It's obvious isn't it? Or it could be The Doctor's mother.

He he! She's looking a bit rough since her last regeneration then. A surgeon would make sense, the Cybermen and Missy would perhaps need one.
