Theory for 13's last moments (a thread):

In this scene, The Doctor opens the fobwatch, causing her to regain her Timeless Child powers, which she uses to defeat The Master. However, this soon starts to take its toll on her, and The Doctor's mind starts to burn up..

mind starts to burn up. With very little time left, The Doctor astral projects into her true form (an androgynous amalgamation of all her prior and future incarnations) and debates on what to do. With the fobwatch destroyed, there is no way for her now to shut off her..

Memories again, and that even if she were to regenerate, it wouldn't spare her from all the pain that's driving her mad. The Doctor eventually realises that there's no easy way out of this. So she makes a compromise..

The Timeless Child Memories will be stored in a vault in the Tardis, never to be opened unless future plots require them to do so. The Doctor's soul, along with her Doctor exclusive memories and powers, however, will be stored into a new fobwatch to be picked up by..

Whomever's worthy. Basically, it's a situation similar to the transition from the crispy Master to Ainley where The Doctor has to steal a new body to carry on their legacy. With her mind made up, The Doctor returns to..

Her body, living long enough to drop Yaz off and finally kiss her. She sets the coordinates for the Tardis to land in Totters' Lane junkyard, figuring that it'll only make sense for the next generation of Doctors to start where the first one began..

What follows is a stereotypical New Who regeneration scene where The Time Lord character's hand glows with regeneration energy, they stare at it nervously, and then get into a T-Pose as a golden aura erupts from out of them and they change into their future self..

It's different this time round, however. Instead of the regeneration energy being yellow, the energy will be multicolored and psychedelic, hinting that a completely different process is happening altogether. And instead of regenerating into..

The 14th Doctor, The Doctor's body will simply vanish, leaving behind only a small fobwatch left in her place, waiting for a new entity to find it and take her rightful place as The Doctor..

A few months later, Yaz is giving a talk at Coal Hill School with her new girlfriend (who looks conspicuously like 13), and on her way home passes by the junkyard, noticing The Tardis. Yaz's 13 lookalike girlfriend pauses for a moment smiles at Yaz saying:

"You know what I think? That Doctor of yours must've been brilliant!". Yaz smiles, and the 2 walk off into the sunset, bringing the Chibnall era to an end..

That's my theory. What do you think?
