Doctor Who: How Jodie Whittaker's 13th Doctor regenerates

Jodie Whittaker has left the TARDIS.

Her 13th Doctor has regenerated after a battle between the Master, the Daleks and the Cybermen in the 90 minute finale, entitled The Power of the Doctor.

In a surprising twist, Whittaker's 13th Doctor regenerated alone on a rock next to the TARDIS, having decided she needed to do this on her own after a final confrontation with Sacha Dhawan's Master.

Having farewelled Yaz (Mandip Gill) by the two of them agreeing never to say goodbye and having had ice cream atop the TARDIS in orbit above the Earth, 13 took herself to regenerate having been fatally blasted by the Master's one last gasp attempt to defeat his nemesis.

Turning to the TARDIS central console, she said "Look after the next one" before saying she was "gonna take in one last sunrise" and stepping outside.

As she stood atop the rock, with the sun on her face and in a broad smile, Whittaker's Doctor uttered her final words.

"Oh the blossomiest blossom. That's the only sad thing - I wanna know what happens next."

As the regeneration energy darted around her and the end neared, Whittaker's Doctor said her goodbye with the words "Right then, Doctor whoever I'm about to be, Tag, you're it."

Within seconds of the regeneration happening, the new Doctor was unveiled - the return of David Tennant's incarnation of the Doctor, in full costume.

With the words "I know these teeth" followed by "What, what, what" the show ended on a cliffhanger, with a trailer for Doctor Who's 2023 revealing more.

Doctor Who will return in 2023.
