Did You Know?


This story introduces the first female Doctor, as actress Jodie Whittaker takes over from Peter Capaldi. See more »


The First Doctor acts as if he is astonished that he will eventually regenerate into another person. Yet, by the time the First Doctor has reached this point in his life, he has already experienced the events of Doctor Who: The Five Doctors and Doctor Who: The Three Doctors: Episode One in which the First Doctor was made very much aware that he would eventually regenerate into several different people. However, it has been previously explained in Doctor Who: The Day of the Doctor and Doctor Who: The Doctor Falls that earlier incarnations cannot retain any memory their meetings with later incarnations.

Great send off for Peter.
25 December 2017 | by ManwhofellSee all my reviews

This was a very good episode, worth the wait. The whole transition to Jodie's doctor doesn't overshadow the episode. I hate that it was announced ahead of time like it was because we obviously knew how it's going to end, just not the road that was taking us there. Peter & David were fantastic, as usual. It was nice to see a few old friends along the way as well. A solid send off for the guy who has replaced Tom Baker as MY Doctor.
