Universe B (Shifting)

One universe was home to versions of the Doctor and Rose Tyler. They were separated (for decades from Rose's perspective and more still from the Doctor's), with Rose being stranded in Pete's World, but Jenny Everywhere eventually found her and brought her back to this universe to be reunited with the Doctor, believing that it would be “better for everyone” if they travelled together once more.

Behind the scenes

As the scenario presented in PROSE: Shifting was presented by the story's author as an “AU” relative to the “official” Doctor Who universe, this universe is not the Third Universe but merely a parallel universe extremely similar to it, its history technically diverging after the Bad Wolf incident (with Rose unwittingly ceasing to age) but, in practice, becoming distinct from official Doctor Who at some point in the Thirteenth Doctor's lifetime.
