The Timeless Children (TV story)

The Timeless Children was the tenth and final episode of series 12 of Doctor Who.

The episode brought to light an account of the Doctor's origins in which, prior to becoming the First Doctor, they had lived many forgotten lives as the Timeless Child. This new thread in the ongoing tapestry brings the Doctor, once again, to the forefront of Time Lord history.

In this new account, the Timeless Child was discovered near a boundary to another dimension or reality by the Shobogan traveller Tecteun, who took her in as her own. Her regenerative abilities were attentively studied by Tecteun, and eventually replicated. This is put forward as the true origin of regeneration on Gallifrey. A radical result of this retroactive continuity is that the Doctor, in their earliest lives, was the biological template upon which Time Lord society was founded.

It also offers a new explanation for pre-Hartnell incarnations like the so-called "Morbius" Doctors, and continues to push the mystery around the incarnation of the Doctor played by Jo Martin.
