Back in the 1980s, Doctor Who was going through such a slump in ratings that it was about to be cancelled if something couldn't be done to revive the show's fortunes.

New showrunner Andrew Cartmel came up with a plan to bring back the mystery of the Doctor's origins, casting him as more than just another Time Lord. Hinted at through scenes in the Seventh Doctor's storylines, the Cartmel Masterplan would have placed The Doctor as The Other, a mythical figure who stands at the very beginning of Time Lord history, alongside Omega and Rassilon, and helped them to overthrow the cult of Pythia.

Sadly the show was cancelled before anything but a few intriguing hints could be dropped, but it looks like Chris Chibnall was paying attention. The Timeless Children started his own master plan, with the triumvirate reveals that The Doctor wasn't Gallifreyan, had virtually unlimited regenerations compared to regular Time Lords, and had been continually mind-wiped while working for interventionist black-ops group, The Division.

While this sets the scene for plenty of future storylines, these reveals cast a new light over these five important scenes from The Doctor's history, showing them in a brand new way.
