of Enros, the Undying One. Enros believes that he created the Miracle and that his death will mean its destruction; he also believes that one day aliens will descend and worship him. When Chris refuses to do so, Kat is taken to be executed while Enros prepares to sacrifice Chris in public before his followers. Dr. Who and Jason travel to the decrepit leisure world Avalone, where the Doctor's former companion Mel has been stranded alone for months. At first, she's delighted to see the TARDIS, but then Dr. Who and Jason imprison her in Galactic Prison along with the Doctor. Dr. Who and Jason then land on the Miracle, venture inside and kidnap Benny, but while they’re busy Jason's attention wanders and the fictional Galactic Prison vanishes—leaving Mel and the Doctor at the mercy of the fictional dinosaurs which Jason left to guard the grounds. He eventually forgets about the dinosaurs as well, but by that time many of the planet's primitive natives have been slaughtered. The angry primitives blame the Doctor and Mel and prepare to burn them at the stake, but they are saved at the last moment when Dr. Who and Jason return with Benny, causing the Prison and the dinosaurs to return. The Doctor and Mel are no longer within the confines of the prison, and thus escape as the dinosaurs tear into the fleeing tribesmen. Mel, however, has begun to worry about the Doctor's newly secretive nature and is puzzled by Dr. Who's claim that the Doctor is responsible for the destruction of the Althosian system and the Silurian Earth. Roz emerges from hiding to rescue Benny from Dr. Who and Jason, but when they are reunited with the Doctor, Mel is appalled by his new gun-toting, casually violent companions. Together, they steal a cartoon spaceship from the Prison and attempt to return to the Miracle, but Jason and Dr. Who pursue them in the TARDIS. Jason decides that the TARDIS has weapons, and it therefore does—and Dr. Who shoots down the escaping prisoners’ ship, blowing it up in the vacuum of space... Dr. Who and Jason then return to Detrios to arrest Chris, and the materialisation of the TARDIS distracts Enros’ followers just as Chris is about to be sacrificed. Still disoriented and confused from the drugs which the cultists gave him, Chris accuses Dr. Who of trying to commit genocide, and Jason
