Tennant's second incarnation is outwardly similar to the Tenth Doctor, but with a more sentimental and affectionate persona, and a weariness that reflects his life experiences in the centuries since.

[2] Liberation of the Daleks leads directly into the Fourteenth Doctor's next televised appearance – a minisode aired during the Children in Need telethon on 17 November 2023, informally titled "Destination: Skaro".

Encountering the alien Meep who plans on destroying London, the Doctor is forced to trigger the metacrisis, granting Donna access to the knowledge that will enable them to save the city.

Donna seems to perish until it is revealed that Rose has inherited some of her mother's repressed Time Lord abilities, allowing the DoctorDonna's powers to be shared safely between the two.

The TARDIS crash lands aboard a spaceship that is adrift at the farthest edge of the universe, where they encounter shape-shifting entities known as "Not-Things".

When they return to Camden, a few days after their departure, they discover Wilf (Bernard Cribbins) has been keeping watch for the TARDIS, who warns them that the world is coming to an end.

[11][12] Davies initially teased their return by not disclosing the true nature of it, hinting that Tennant and Tate may have been reprising their roles via flashbacks or via an alternate universe.

Davies's return also led to speculation that an actor he had previously worked with in other projects would join him as the Fourteenth Doctor, with Olly Alexander, Lydia West, Omari Douglas, T'Nia Miller and Fisayo Akinade ranking highly in bookies' odds.

[26] Tennant and Tate appeared as the Fourteenth Doctor and Donna Noble in three specials to commemorate the programme's 60th anniversary in November 2023.

[36] Constance Grady, writing for Vox, criticised the character's bi-generation, which allowed the Fourteenth Doctor to live on in-universe.
