Recap / Doctor Who S33 Short "The Battle of Demons Run: Two Days Later"
The Paternoster Gang is formed. Next stop: Victorian London.

The one where we learn how Strax got better.
And how an unlikely trio came to be.

Demons Run. It's two days later.

Strax wakes to a voice calling his name, to find Madame Vastra and Jenny Flint standing over him. Jenny insists, much to Strax's disappointment, that he is not dead and has made a full recovery. Also, Vastra and Jenny have noticed that he is alone and make a tempting offer: to come with them to this strange planet of "London", full of fancy dresses and an awful lot of running to do. It can be viewed online.
