A second person asked: “Don’t be fooled. Billie IS NOT the Doctor. Where is ‘and introducing Billie Piper as The Doctor’?”

A third noted: “Something strange is that they didn’t call her 16 in the tweet or the credits. When David came back it was “Introducing David Tennant as The Doctor”, but just “Introducing Billie Piper”?

It remains to be seen when fans will learn more about Piper’s role as no announcement has been made about the next season.

Speaking to the Radio Times in April 2025, showrunner Russell T Davies said he was still waiting for confirmation from Disney Plus, who has co-produced the show with the BBC since 2023.

“There’s no decision until after season two,” said Davies. “It’s funny, because even people who work on the show think that means we’re having secret meetings about it. People I work with every year say, ‘What’s really happening?’ and I’m going, ‘Nothing! No meetings, nothing.’

“That’s when the decision is – and the decision won’t even be made by the people we work with at Disney Plus, it’ll be made by someone in a big office somewhere. So literally nothing happening, no decision.”

In a statement Piper said: “It’s no secret how much I love this show, and I have always said I would love to return to the Whoniverse as I have some of my best memories there, so to be given the opportunity to step back on that Tardis one more time was just something I couldn’t refuse, but who, how, why and when, you’ll just have to wait and see.”

Shortly after the finale aired, the actress shared a post on Instagram holding a rose with the caption that read: “A rose is a rose is a rose !!!”
