Gravis distracted by TARDIS obsession

The Doctor lures the Gravis into the TARDIS with a false offer of surrender, knowing the Tractator leader’s pathological obsession will override tactical judgment. Once inside, the Gravis’s focus narrows to controlling the ship itself, ignoring the flawed state of its systems. As the Doctor manipulates the Gravis into activating controls, the Tractator’s absorption unravels the group’s centralized cohesion. The moment crystallizes the Gravis’s fatal flaw—willing to abandon his mission for the promise of cosmic domination through the TARDIS, leaving his forces vulnerable and exposing the flaw in the Tractators' plan.

TARDIS Control Nexus

The TARDIS serves as the deceptive battleground where the Doctor stages a surrender offering while secretly orchestrating the Gravis’s entrapment. Its spatial distribution circuits, mocked as operational, become the centerpiece of the Doctor’s misdirection. The ship’s fragmented state and enticing promise of mobility ensnare the Gravis, diverting his focus from external threats.

Before: Temporally and spatially fractured, with components distributed to avoid Tractator detection; externally battered but functionally camouflaged as intact.
After: More components remain exposed or misaligned as the Gravis’s absorption intensifies, increasing pressure on the TARDIS’s already unstable systems.
Door Handle on the TARDIS Fracture Shard

The Door Handle on the TARDIS shard becomes a secondary point of access and egress. While the Doctor lures the Gravis inside, the shard is used to secure the TARDIS from further Tractator incursion, and later Tegan uses it to reinforce the barrier behind her, underscoring the vulnerability of the ship’s containment.

After: Shoved shut by Tegan, reinforcing the fragile sanctuary and cutting off the Gravis’s reinforcements.
Azmael's Ultimatum Actuator

The Control Switch is the pivotal device the Doctor leverages to deceive the Gravis. By having Turlough guide the Gravis to press it, the switch becomes the trigger for the Tractator leader’s absorption into operating the TARDIS. Its activation falsely signals to the Gravis that the ship’s functions are within his grasp when, in fact, it deepens the Doctor’s manipulation.

Before: Normal-looking control interface on the TARDIS console; non-functional …
After: Pressed and briefly activated, drawing the Gravis’s attention …
Before: Normal-looking control interface on the TARDIS console; non-functional but presented as operational.
After: Pressed and briefly activated, drawing the Gravis’s attention and initiating his absorption process.
TARDIS Spatial Distribution Circuits

The Spatial Distribution Circuits provide the Doctor’s primary misdirection; he claims they are switched in to optimize packing efficiency (a lie) but functionally they strand TARDIS components across space. The Gravis’s obsession with operating the circuits keeps him distracted while the Doctor observes how his absorption unfolds.

TARDIS Visual Diagnostic System

The Autoscan is weaponized by the Doctor’s manipulations, projecting misleading holographic data to convince the Gravis that the TARDIS’s temporal and spatial functions are accessible and coherent. Its false readings reinforce the narrative of surrender while masking the TARDIS’s actual compromised state.
