wrong there, where Barlow leads a squad to the pit and learns what has happened. The Daleks are currently confined to the pit area, but are building a power transmitter which will enable them to venture further into the surrounding countryside. Barlow and his men fight the Daleks and Robomen, while the Doctor, David and Donna break into DA-17 to find out what is really going on. Since the Daleks are no longer receiving power from Haldoran’s stores, the Doctor increases the embryo production in the hatchery, draining power from the Artefact’s reserves; and while the Daleks are busy dealing with this, he also sets the factory production reactors to overload. Meanwhile, the Master seizes the core of the matter transmuter and tries to escape; the Doctor, Donna and David run into him, and when the Master tries to shoot the Doctor, David pushes the Doctor aside and is killed himself. The Master retreats back to his TARDIS and leaves with Susan as his hostage, and the Doctor and Donna escape from DA-17 moments before its reactors overload and explode, wiping out the Daleks. The Doctor slowly recovers from his injuries, and Donna and Barlow decide to marry; partly for political convenience, but not entirely.

The Master, not realizing that his hostage was also Gallifreyan, was caught off guard when Susan amplified a shriek of pain and despair through his own TARDIS’ telepathic circuits, incapacitating him; he tried to flee out onto the surface of Tersurus, but was caught in the explosion and nearly killed when Susan turned his own TCE on the matter transmuter. Susan then left Tersurus in the Master’s TARDIS, and the crippled Master remained to be discovered by Chancellor Goth of Gallifrey who was investigating the renegade TARDIS materialization. The Doctor decides to leave Susan her freedom, and sets off once again in search of Sam. Continuity This story provides a major reason for why the Master had regenerated into his final form when the Fourth Doctor met him in The Deadly Assassin.
