Doctor Who has been in a position of flux for a while now, but at the very least, it left off on an exciting note. At the end of the latest episode, the Fifteenth Doctor, played by Ncuti Gatwa, started to regenerate, but this didn’t quite make sense, as we didn’t have any word as to who would take on the role next, which is the show’s usual protocol.
So when the Doctor regenerated into the form of Rose Tyler, the fan-favorite companion from Christopher Eccleston and David Tennant’s tenure as the Doctor, played by Billie Piper, fans were shocked. Is Rose the Doctor now? A major fan theory has emerged tying the upcoming 2026 Christmas special with a devastating 2008 episode, and it certainly seems like the most logical explanation.
