But that was so much fun! I guessed Porridge was the Emperor very early on - he looked like the statue, he was missing, he had a certain authority. I would love to see him again. (Not that even ruling one galaxy would be possible, but hey!)
The Doctor playing himself and shifting between being himself and the cyberplanet [Edit] cyberplanner]* was excellent, and I liked all the soldiers in the platoon too.
Clara really took charge of that platoon as if she was used to authority; I wonder if she can somehow access other versions of herself whether she realises it or not.

And yay, more Vastra, Jenny, and Strax next week! And perhaps River Song?
