‘Doctor Who’ Has the Perfect Answer to Its Biggest Doctor Problem

Doctor Whois undergoing a major shake-up, as the 2025 season ended in a massive twist where Ncuti Gatwa‘s 15th Doctor regenerated into a familiar face: Billie Piper, who previously played one of the Doctor’s most stalwart companions, Rose Tyler. While Piper’s surprise return sparked speculation about her becoming the next Doctor, her exact role remains unconfirmed. Former showrunner Russell T. Davies has since revealed that the regeneration twist was conceived amid uncertainty over the show’s future.
