This episode has everything. You have a fan-pleasing return in the form of Osgood, some neat references to Rose in her Bad Wolf form and the Slitheen, AND a cameo from Jodie Whittaker. I'm interested to see what brings the podcasters back together in the next episode, seeing as this one sees them going their separate ways after Abby decides to join UNIT. Something's got to persuade Cleo and Shawna to (presumably) visit Madame Vastra.
