Steven Moffat, who is the current man behind Doctor Who…the showrunner, the impressario, the God…has trained squads of Ninja Assassins. Probably there are a couple of people in this audience tonight who are plants.If I actually got to the point of saying ‘OK, I will tell you what you want to know’…something would happen. And then I would crumble. Smoking gently, probably. A mysterious black figure would exit and next be seen in Cardiff, saying ‘Mission accomplished’. Steven Moffat would go ‘Good. And he didn’t say anything?’ And the figure would say ‘No’. I tell you NOTHING.
