The Doctor lies. This we know. Steven Moffat, in public, sometimes lies too. This we also know.
How far then, should we believe Moffat when he categorically states that not only will he not be bringing the Master back, but there are also no plans for a special episode to celebrate Doctor Who's tenth year since its 2005 revival?
Here's what the Who showrunner said on both matters at yesterday's "Deep Breath" Cardiff and London premiere Q&As:
Will the Master be coming back anytime soon?
Steven Moffat: "[Abruptly] No. [Laughter] I accidentally just said the truth! No, not really. I think the story’s sort of done. I thought what Russell [T. Davies] did with that was so brilliant, because I did think it was over. Once you’d lost Roger Delgado who was so brilliant, it was tough to keep it… it’s like Moriarty in Sherlock - yes, I know - you think, 'you’re a great master villain, you know what you do a lot, you lose! You’re always tremendously confident and then you’re humiliatingly defeated and you don’t remember that the next time you pop up with your ridiculous plan'. So no, the Doctor doesn’t really need an arch-enemy, so we’ll go for new ones. So, sorry John Simm."
Are there any special plans for the 10th anniversary of the show's return?
"We've only just done the 50th! After doing a huge fuss over 50 years of Doctor Who, and bringing the nostalgia into the show, I think it's time to aim forward. We're not planning that. Unless I'm lying!".
You said it, Mr Moffat.
