As was suggested by Peter Capaldi, we have around seven months until we get a brand new full series of Doctor Who but, between now and then, there’s the small matter of this year’s Christmas Special; details for which have been kept under wraps…
Until now…
Steven Moffat has finally begun teasing us with small details as filming begins on the Christmas Special. Speaking to BBC Newsbeat, Moffat said:
“We’ve just started working on the Christmas episode. It’s got a lot of heart, but it’s got a lot of brain too. Figure that one out.”
Well then, let’s try it!
So ‘a lot of heart’ could easily refer to the Doctor himself – after all, he’s got of them – which makes us think we might see another appearance from Missy. She certainly covers the ‘heart’ and ‘brain’ quota of that brief statement.
Or perhaps for ‘brain’ we should be thinking ‘head’ namely the severed bonce of Nardole – he certainly needs to be reunited with his body after the events of The Husbands of River Song, could this yuletide see Matt Lucas’ Nardole join the TARDIS crew?
With the Christmas special filming during the current Series 10 schedule – although the Christmas episode usually shoots around this time – it seems to suggest that either Nardole or Bill (or indeed both) will appear in the festive episode.
In fact, fans have already snapped Nardole himself Matt Lucas on set already.

Or perhaps this is all rubbish and – be still my beating ‘heart’ – could it all be a thinly veiled reference to The Brain of Morbius! Please say yes!
So what do you make of Moffat’s cryptic comment? What do you want to see happen this Christmas? And, more importantly, what don’t you want to see? Not naming any names *cough* River Song *cough*
