It was months ago now that Neil Gaiman first said that we should expect to see 'something or someone not seen since The War Games' within his episode and it has left fans guessing who or what it could be. A few days ago over on the forum, Exterminate posted what has turned out to be a very interesting theory:
Neil Gaiman said that his episode (ep4) will contain something or someone not seen since the War Games. How about if it was the Time Lords Communication Box? Here it is in The War Games
And here is something from the trailer which could be the same thing....?
Could it be that somehow the Doctor recieves a message from the Time Lords? Maybe it is one sent before they are wiped out, or it could be from Idris (Suranne Jones) the 'old aquaintence with a new face' or maybe even some Time Lords in hiding? Or maybe it is a trap and someone other than a Time Lord uses it to comminicate with the Doctor. Also, if you look at Amy and Rory in the background, they are wearing the clothes from the filming of Gaimans episode, so it is safe to say that the glowy box belongs in that story, even if it isnt the communicator device.
So that is what Exterminate thinks, but what about you lot? Let us know below
