History Recap / DoctorWhoS33E12NightmareInSilver

Webley has an empty Cyber-suit in his home, which he uses as [[https://en.wikipedia.org/wiki/The_Turk a parlour trick when he gets people to play chess with it]]. Inside is actually a little person nicknamed "Porridge" (Creator/WarwickDavis!) who quickly befriends Clara. Just as the whole gang is about to head back home, the Doctor realises that things are ''very wrong'' on this planet, and goes off to investigate, telling the kids to stay put. They don't, of course, and while Angie, Artie and Webley get kidnapped and put into a "walking coma" by the quickly revived Cyberman, the Doctor is infected by Cybermites (like Cybermats, only quite tiny) and turned into a ''magnificently'' LargeHam in the process. The Cybermen were only looking for clever young children, like Angie and Artie, but a ''Time Lord'' is infinitely more useful. And they really didn't expect to find one here... after all, the Doctor has been deleting himself from history across the universe.

The Doctor tells the Cyber-Planner, who's taking over the Doctor's mind, that he could simply commit HeroicSuicide and regenerate on the spot to destroy the Cyber-Planner's implants -- and, via the Cyberiad network, every Cyberman it controls. Instead, they battle it out both in the Doctor's subconscious and over a game of chess. The Doctor's fully aware that the Cyberplanner will betray him no matter who wins, but does what he can to protect the children. Meanwhile, Clara takes full advantage of the Doctor's BavarianFireDrill and takes charge of the platoon. She spends most of it trying to prevent the soldiers from blowing up the planet, since that's been their modus operandi ever since the last war with the Cybermen. They even blew up the Cybermen's entire galaxy. Porridge tells Clara that he feels tremendously guilty over that -- because no matter how much he tries to think about all the lives that were lost that day, all he can really bring himself to care about is the poor man who had to push the button.

And somewhere drifting in space, amongst the remains and debris of the planet that housed the newly reborn Cybermen...''a Cybermite is still active.'' The new era of the Cyber-Legion has arrived...

** The Doctor threatens to [[TakingYouWithMe regenerate to purge a malevolent force possessing him]], even though he has [[OutOfContinues no regenerations left]] (thought viewers are not yet aware of this fact), which is exactly [[Recap/DoctorWhoS21E7TheTwinDilemma what his old teacher Azmael did]], committing suicide to kill Mestor, who was possessing him at the time.
