So, the final episode to have all the UNIT family together and there's a lot going on - the story is about to change location, and indeed performance style, as the TARDIS sets sail for Atlantis, but before that there's plenty of TARDIS based jeopardy, including the creation of a cliffhanger out of nothing. Will guest Alex Moore (host of The Unsung Heroes of Doctor Who) and host Toby Hadoke choose the same favourite thing or might they both be better off speaking backwards?

WARNING - this was one of the first podcasts Toby recorded and so he ate crisps during this episode. It has had some of the worst crisp eating edited out since the episode was originally released but there might be some residual chomping, so if you're sensitive to horrid sounds be warned. It's better than it was though, and mostly at the beginning, and Toby promises never to eat during a podcast again.
