I’m not entirely certain whether this is official, but it is still well done. But I do know that this trailer makes me wish to have a Tardis even more! I could just go on and skip right to November 23, of course!
Do you think they are still planning to do something with the Doctor’s name along the lines of the hints we had received up until now, as highlighted in the video? Or is that all a red herring? Or is it something which will, if it ever appears on the show, only happen at the end of the Doctor’s lives?
