A rare publicity still of The Boomtown Cybermats performing their best known song.
We go into these last two episodes of Doctor Who's tenth modern season awaiting the full details of how John Simm's Master will interact with Missy, and where this unlikely reunion fits in with the reappearance of the original version of the Cybermen.
We also know that the Mondasians were there the very first time we saw the Doctor regenerate. We know what's coming, and will what happened before inform Peter Capaldi's ultimate fate in some way? He revealed on TV that he had already filmed his 'death', but also still had to return for the Christmas special. Is this simply to do with the non-linear way that programmes are filmed, or should we take note of Steven Moffatt's hints that there will be something different about this regeneration?
Not long now before we find out.
