The Doctor, meanwhile, has joined with intergalactic explorer Captain Cook and his young female companion Mags, who had also been invited to the circus. They all are told by the Ringmaster that they will be expected to entertain in the near future. Mags joins the Doctor as he explores the circus to try to learn what really is going on. They find a well, with a glowing energy source at the bottom, featuring an eye symbol similar to that on the Chief Clown's kites and Morgana's crystal ball. Just then, they are cornered by Cook along with several mechanical clowns, informing the Doctor is on next. The Doctor escapes, encountering a worker named Dead Beat who has a medallion with the same eye symbol.
