The Invasion of Time Part 6

The Doctor must outwit the Sontarans, who seek to capture the Great Key and exploit the TARDIS, while navigating the labyrinthine ship and confronting his own past.

In this installment of 'The Invasion of Time,' the Doctor finds himself trapped in his own TARDIS, pursued by the Sontaran warlord Stor and his cohorts. The Doctor's plan to thwart the Sontarans involves a series of strategic maneuvers, including setting a biological barrier, creating a maze of identical storerooms, and utilizing his loyal companions, Leela and Rodan. As Stor closes in, the Doctor forges an alliance with Chancellor Borusa, who possesses knowledge of the Doctor's past and the significance of the Great Key. The Doctor's journey takes him through various sections of the TARDIS, from the console room to the swimming pool and the workshop, as he works to disable the Sontarans and prevent them from obtaining the Great Key. The climax features a confrontation between the Doctor and Stor in the Panopticon, culminating in the Doctor's use of the Demat gun to eliminate Stor. Ultimately, the Doctor reflects on his actions and his connection to the Time Lords, as Leela and K9 remain on Gallifrey.

The narrative beats that drive the story

Act 1

The narrative opens with the Doctor stabilizing his TARDIS, an act that inadvertently traps the invading Sontarans within its labyrinthine interior. He then strategically disables the fail-safe controls, ensuring the Sontarans cannot easily reactivate the ship's systems or escape. Pursued by Stor and his warriors, the Doctor, accompanied by Leela and Rodan, attempts to navigate the vast, often confusing, interior of the TARDIS. This leads to a running gag about the Doctor's supposed 'perfect sense of direction' as they repeatedly encounter identical storerooms and service tunnels, highlighting the ship's immense and disorienting scale. Meanwhile, Stor, frustrated by the Doctor's tactics and the TARDIS's archaic design, orders Kelner to reactivate the systems, but they find the Doctor's modifications have created an impenetrable lock. The Sontarans eventually force their way through the inner door, intensifying the pursuit. Recognizing the escalating danger, the Doctor prepares for a deeper confrontation by entrusting the Great Key to Rodan, whom he places under hypnosis, instructing her to guard it with K9 in the workshop. With this crucial artifact secured, the Doctor, Leela, and Andred set off to locate Chancellor Borusa, seeking an alliance against their common enemy. This initial act establishes the enclosed, high-stakes environment and the Doctor's immediate defensive strategies.

Act 2

Act Two plunges the Doctor and his allies deeper into the TARDIS's complex interior as they are relentlessly hunted by Stor and his forces. Stor, utilizing a tracer, discovers the Doctor has erected a 'biological barrage,' preventing the Sontarans from tracking human life forms. Kelner, however, identifies a workaround: locating and disabling the ancillary generator powering this barrier. This development shifts the hunt, as Kelner leads Stor through the TARDIS's disguised power station, eventually finding and removing the crucial circuit breaker, thus reactivating the Sontarans' tracking capabilities. Concurrently, the Doctor locates Chancellor Borusa in the TARDIS swimming pool, where they discuss the significance of Rassilon's artifacts, particularly the Great Key, and the existential threat posed by the rapidly multiplying Sontaran clones. The Doctor, Borusa, Leela, and Andred attempt to evade their pursuers through a series of tactical splits and diversions, leading to a tense encounter in the TARDIS sickbay where Andred is wounded by Stor. Leela takes the injured Andred and Borusa to the workshop for safety, while the Doctor remains to further confound the Sontarans. Back in the workshop, with K9 and Rodan, the Doctor unveils his ultimate, secretly constructed weapon: the Demat gun. He arms it with the Great Key, demonstrating its immense power by making a Sontaran vanish. Under duress, Kelner reveals Stor's current location in the Panopticon, setting the stage for the final confrontation.

Act 3

The climax unfolds as the Doctor, armed with the Demat gun, confronts Stor in the Panopticon, the heart of the Time Lord Citadel. Stor, driven by a fanatical devotion to the Sontaran Empire, reveals his intention to detonate a grenade, not only to destroy the Doctor and the Time Lords but also to obliterate the entire galaxy and his own battlefield, viewing it as a 'small price to pay' for denying the Time Lords their power. In a decisive moment, the Doctor uses the Demat gun on Stor, causing a blinding flash and Stor's complete disappearance. The Doctor collapses, disoriented, the Demat gun gone, leaving only the Great Key. Returning to the workshop, the Doctor is surprised to find himself wearing the Sash of Rassilon, a symbol of Time Lord presidency. Borusa explains that the Doctor, through his actions, has saved Gallifrey from both the Vardans and the Sontarans, though the Doctor has no memory of these heroic deeds, attributing his amnesia to the 'wisdom of Rassilon.' With the immediate threat neutralized and his forgotten heroism revealed, the Doctor prepares to leave Gallifrey. However, his companions make unexpected decisions: Leela chooses to remain on Gallifrey with Andred, and K9, loyal to Leela, also decides to stay. The Doctor, accepting their choices with a bittersweet smile, departs alone in the TARDIS. As the TARDIS dematerializes, a final scene in the console room reveals a large cardboard box labeled 'K9 Mk II,' indicating the Doctor's resourceful preparation for his continued adventures.
