The Doctor Falls (TV story)

, written by Steven Moffat, was the twelfth and final episode of the tenth series of Doctor Who produced by BBC Wales. It featured the departures of both Bill Potts and Nardole, and the apparent death of after ensuring the end of. Expanding on the Twelfth Doctor's regeneration teased in the previous episode, it saw him mortally wounded in battle against the Cybermen. The regeneration would be postponed, however, as the Doctor refused to change.

The story featured several connections to the 1966 serial The Tenth Planet, including a story featuring humans from Mondas and featured appearances by the Cyberman from said planet. More surprisingly, it featured the surprise return of the First Doctor now portrayed by David Bradley, who had previously portrayed William Hartnell in the docudrama An Adventure in Space and Time, in a scene set during the finale of The Tenth Planet iself.

Plot
The episode opens to a group of farmers on Floor 0507 facing against the prototypes from Floor 1056, shooting them down by night to then restrain on wooden crosses by day. A school child is out in the field one morning when a shuttlepod blasts through the ground. From the rubble, a Cyberman walks out carrying an unconscious Doctor.

Sometime earlier, The Doctor awakes on top of the hospital, soon recalling how he was subdued by Missy and the Master. The Doctor, now restrained in a wheelchair, watches the two incarnations of the Master taunt him on the many deaths the Doctor has had and wanting to find out new ways to kill him. The Master and Missy dance and flirt with each other and gloat of their plan of the Cybermen converting all the humans on the ship. However the Master is stunned to find that the Cybermen are heading towards the building that they are perched on. The Doctor explains while he was knocked down by Missy, he altered the signal to focus on the Time Lords present and brags that he is the only one who has ever been able to stop so many Cybermen at once. Missy knocks the Master out and frees the Doctor from his restraints.
