"Doctor Who: Controversial Canon Changes and Surprising Reviews"
Doctor Who showrunner Russell T Davies has hinted that the recent bi-generation of the Fourteenth and Fifteenth Doctors could potentially make all previous Doctors in their respective timelines return. This opens up the possibility of a "Doctorverse" where multiple Doctors can coexist. Davies also stated that this move allows for the controversial changes to the Doctor's mythology to be considered canon or not, depending on individual interpretation. The upcoming Christmas special, "The Church on Ruby Road," will feature Ncuti Gatwa's first solo episode as The Doctor alongside his new companion, Ruby Sunday.
