Liam has disappeared completely, and Danny has died, leaving Ben and Dan as the only remaining team members, but with help from Dan's new best friend Bob the flower alien, they must hold out against an onslaught of zakatrons
This was the first episode in which Liam talks about the fact that he was the Doctor's final companion.
This episode was originally meant to be a one-off special before Series Two, and in a very early draft Robin Turner and his team were introduced as part of the story.
