…because let’s face it, we’re already excited.

Peter Capaldi and Steven Moffat’s final series was already shaping up to be one hell of a rollercoaster ride, but then it was announced that John Simm will be making the master of comebacks when he reprises his role as the renegade Time Lord after 7 years. And thus, the fandom went into overdrive.

He won’t be the only one, either, as he’ll be coming face to face with Michelle Gomez as Missy, who has irresistibly inhabited the part since 2014. Crikey!

But what’s it all about? How is Missy’s predecessor returning? What happened to him after the events of The End of Time, Part Two that led to his regeneration? And what, for the love of all things Mighty Jagrafess, has he got up his sleeves this time round?! Some fans are already speculating that it is he who lies within the elusive vault that the Doctor has sworn to protect, but that might transpire to be someone – or something – else entirely…

We’ve already caught a glimpse of him in the latest trailer, so let us know what you can deduce – if anything – in the comments below, as well as your general theories about his grand return. It’ll be two Masters for the price of one, and the Universe is already shaking.
