‘The Day of the Doctor’ aired at the weekend and saw Piper playing The Moment.

Moffat told journalists at the Official Doctor Who Celebration in London yesterday: “I thought the story of Rose, which was beautiful, was done. I didn’t want to add to it, I didn’t feel qualified to add to it. That was always Russell’s story. The way Russell [T Davies] ended it in ‘The End of Time; was perfect. I didn’t want to stick another bit in. It would be wrong.”

He explained: “But we did want Billie Piper, one of the absolute heroes of Doctor Who, back in the show without interfering in the story of Rose Tyler. I think I might have spoiled something if I had done that. Billie represents the revival of Doctor Who, more than anyone else.”
