The Doctor discovers Dastari's day journal and the Time Lords' objections to the Kartz-Reimer experiments. In Spain, Chessene, Shockeye and a Sontaran, Major Varl, take possession of a hacienda by killing its owner, Doña Arana. Dastari and the Sontaran Group Marshal Stike carry an unconscious Second Doctor towards the hacienda. Peri is attacked by a humanoid in rags. The Sixth Doctor and Peri find that Peri's attacker was Jamie, who has been hiding all the while. Under hypnosis, Jamie tells the Sixth Doctor that the Sontarans killed the Second Doctor. The Sixth Doctor explains to Jamie and Peri that what Jamie saw was an illusion designed to make people believe the Doctor was dead and not investigate further. He theorises that the Sontarans also kidnapped Dastari as he is the only biogeneticist in the galaxy who could isolate the symbiotic nuclei that gives Time Lords the molecular stability to travel through time. The Sixth Doctor puts himself into a telepathic trance to determine where his past incarnation is being held. He narrows it down to the Seville area, where the Sontaran spaceship landed. Dastari reveals his plan to dissect the Second Doctor's cell structure to isolate his symbiotic nuclei and give them to Chessene. The Second Doctor protests that her barbaric Androgum nature, coupled with the ability to time travel, will mean that there will be no limit to her evil. Finding the hacienda, Peri interrupts the operation. Sneaking into the cellar, the Sixth Doctor examines the Kartz-Reimer module, a prototype time machine modelled on Time Lord technology, explaining to Jamie how it works. The Sontarans overhear him. Outside, Shockeye knocks Peri out and brings her to the hacienda kitchen. Stike threatens to kill Jamie unless the Sixth Doctor gets into the module and primes it with his symbiotic print, and the Doctor does so, after which, he and Jamie escape the Sontarans. Chessene has a contingency plan after discovering the involvement of two Time Lords. She asks Dastari to implant the Second Doctor with some of Shockeye's genetic material, turning the Doctor into an Androgum. They also intend to eliminate the Sontarans. Chessene interrupts Shockeye when he attempts to cook an unconscious Peri, and stuns him so that Dastari can remove his genetic material. The Sixth Doctor revives Peri, and tells Jamie and her that what he revealed to the Sontarans was not true — he had lied because
