In the clip, which you can see below, the Twelfth Doctor (Peter Capaldi) comes face to face with the First Doctor (David Bradley) and a man named the Captain (Mark Gatiss), who becomes a part of their story after being pulled from the trenches of the First World War. The episode sees the First Doctor struggling to accept his future self, having felt that he'd surely be "younger" than his present form. It's a light scene in what is sure to be an emotional episode with Capaldi's Doctor set to regenerate during the Christmas special as the actor leaves behind the role.

The episode will be the last for both Capaldi, who will be succeeded by Jodi Whittaker's Thirteenth Doctor, as well as Doctor Who showrunner Steven Moffat who helped usher in the new era of Doctor Who on the BBC . Recent rumors have suggested former Doctor Matt Smith will also be brought back for the forthcoming Christmas special, although those rumors appear to be just that for the time being.
