In Doctor Who’s Season 2 finale, “The Reality War,” the Time Lord\u00a0learned\u00a0that Fourteen’s “bi-generation” was a result of his life force\u00a0desperately trying to find a way to survive and continue his\u00a0species.\u00a0<\/p>\n
While setting out to rescue\u00a0Poppy, his daughter created through a wish, the Doctor poured his own regeneration energy into the Time Vortex, triggering a regeneration. In doing so, he\u00a0shifted reality\u00a0so that she could continue to exist as the\u00a0human daughter of Belinda (which, tragically, meant she was no longer his daughter, as well).<\/p>\n
His regeneration did\u00a0follow, with Ncuti Gatwa’s adventurer\u00a0transforming into a female Doctor\u00a0with Billie Piper’s face. She previously played Rose Tyler in the series and was once exposed to the heart of the TARDIS as “Bad Wolf.” That and the fact that she wasn’t introduced as the new Doctor has led to speculation that this is a temporary change before the new Doctor is properly introduced.<\/p>\n
Much has been said about Doctor Who Season 2\u00a0ending\u00a0with a less definitive regeneration before Piper was cast, or, had one not happened at all, then we’d have gotten\u00a0a happy ending with the Doctor and his friends gathering at a party (a scene featured in trailers). Gatwa would’ve continued playing the Time Lord heading into Season 3, but in reality, couldn’t remain committed to the\u00a0show indefinitely when Hollywood is calling.<\/p>\n
In a major tease for the future,\u00a0the Doctor’s granddaughter, Susan, was set to be\u00a0shown from afar alongside\u00a0Poppy, referring to her as “mum,” and confirming that the time-traveller now had a family. Still, with the show’s future so uncertain, Russell T Davies decided on a less open-ended conclusion.\u00a0<\/p>\n
Now, actress Carole Ann Ford, who plays the Doctor’s granddaughter, has revealed<\/a>\u00a0that she shot these scenes with the intention of further exploring Susan and Poppy’s link to the Time Lord down the line.<\/p>\n
