I will try keep this as spoiler free as I can. However there will be one main spoiler, I personally don't think it is a big one, however it is hard to say so don't read on if you are worried. Don't say I didn't warn you!
|The poster for the season 7 finale|
So I am not really interested in going into the episode. However at the end it introduced the Doctors darkest secret. Which apparently is, well, himself played by actor John Hurt. This was introduced with what I thought was a pretty cool shot and title, here it is:
Cool huh, well maybe that shot doesn't do it justice but I love shots with 'Introducing said person as character'. So there is of course plenty of speculation already as to who he is and where he fits into the Doctors timeline. The internet seems to point towards the Valeyard which is an amalgamation of the Doctor's dark aspects, supposedly between the 12th and final incarnation. The Valeyard was introduced with the 6th doctor in Trial of a Time Lord.
Another suggestion which I thought sounded pretty good was that John Hurt was playing the Doctor between the 8th and 9th when the Doctor destroys Gallifrey. Some people thing that John Hurt will be both. Perhaps he will just be the next Doctor after Matt Smith, a new Doctor could be nice. Matt Smith has bene good but there comes a time for the Doctor to move on, just as it was time for the Pond's to go. Who ever he is I am sure not many people will get it right, only the crew of Doctor Who will know. Till November.
Well I am looking forward to the 50th anniversary episode. The return of David Tennant and John Hurt as a mysterious incarnation of the Doctor will hopefully make for a good episode.
