However, nothing has been officially confirmed yet, and this ending could be intentionally misleading. In the episode titled The Reality War, Ncuti Gatwa ’s Doctor regenerates into Billie Piper, who previously played the beloved companion Rose Tyler during two seasons from 2005 to 2006, with a brief appearance in 2008. Fans are now wondering if she might become the next Doctor. Piper herself said :
"Wait and see," adding, "I love this show and have some of my best memories there. Being given the chance to step back into that TARDIS was something I couldn't refuse."
Notably, at the episode’s end, Gatwa and Jodie Whittaker (who guest stars) are credited as the Doctor, but Piper is not. This subtle detail, combined with her vague comments and the lack of an official announcement, has led fans to believe that the finale might be more complex than it seems — perhaps a tease or misdirection. What is confirmed is Gatwa’s departure; he expressed heartfelt gratitude for his time as the Doctor, calling it an unforgettable journey and thanking fans for their support. Gatwa made history as the first openly queer Black actor in the role, starring for two seasons — the second shortest tenure after Christopher Eccleston’s one season.
Doctor Who remains available on BBC iPlayer and BBC One in the UK, and on Disney Plus worldwide. Fans are eager to see what’s next, but for now, everything is shrouded in mystery.
