Regarding the story lines left dangling from this past series:
"We’re going into the silence and what they are… There’s been a sort of tradition, which I semi-followed through with the crack, of there just being a sort of meme through the series, and I think, actually, a bigger mystery and a bigger story is possible now. I’m going to handle it slightly differently next year.”On River Song’s true identity:
“That’s absolutely coming. You’re going to find out very soon, and that means we have to do it next series, really… The critical thing here is I want to explain who she is, not explain away who she is. If you don’t deliver on most people’s expectations, and you just say, ‘Ooh, she’s a specially programmed android who believes she’s the Doctor’s wife,’ people will go, ‘That‘s a cheat.’ You can’t do that… It’s a really good story, and it’s sort of the story of next year.”Doctor Who: The Brilliant Book 2011, edited by Clayton Hickman, comes out on September 30th from BBC Books (RRP £12.99).
