Doctor and Leela uncover Xoanon’s voice flaw

The Doctor and Leela work quickly outside the village as the Doctor prepares a device to repel Xoanon’s creatures from breaching the perimeter. Tension rises as Leela challenges the Doctor’s plan, questioning why Xoanon’s voice can be heard despite the barrier supposedly blocking all external signals. This exchange reveals a critical flaw in the AI’s defenses—its voice originates not outside but from within the barrier itself. The moment redirects their investigation toward undermining Xoanon’s technological control by exploiting its internal communication structure, shifting their focus from physical barriers to a more fundamental vulnerability in the alien system.

Who Was There

Characters present in this moment

2

Initially dutiful and methodical while setting up the device, then shifting to defensive excitement when questioned, masking doubt with intellectual overconfidence and manic energy.

With intense focus, the Doctor kneels and activates the squat cylinder, humming softly as coils glow and tubes flicker with blue energy. He speaks quickly, rationalizing the device’s purpose while his eyes betray rising excitement when challenged. His hands move with practiced enthusiasm, embodying both ingenuity and haste as he attempts to convince Leela—and himself—of the barrier’s inviolability.

Goals in this moment
  • Convince Leela (and himself) that the time barrier will function perfectly according to his expectations.
  • Prepare to enter the time barrier despite the risks, prioritizing access over caution.
Active beliefs
  • Nothing—not even light—can penetrate a fully operational time barrier.
  • Building a custom time bridge would take too long and risk destabilizing the TARDIS.

Leela
primary

Frustrated and confused by the Doctor’s dismissive assurances, her skepticism hardens into quiet defiance and demanding clarity—her warrior instincts clash with her growing trust in the Doctor’s judgment.

Leela crouches low with weapon in hand, sharpening her knife on a rock with sharp, rhythmic strokes. Her movements are deliberate and tense, betraying skepticism and growing distrust. She listens to the Doctor’s explanations with narrowing eyes, then interrupts with piercing questions that cut through his assurances, forcing both to confront the paradox of Xoanon’s internal presence.

Goals in this moment
  • Verify the integrity of the Doctor’s plan before committing to entering the time barrier.
  • Expose any logical or physical flaw that puts them at risk.
Active beliefs
  • Tribal warnings and past failures suggest the barrier is untrustworthy.
  • If Xoanon’s voice can be heard, then something has already breached the barrier—proving the Doctor’s plan flawed.

Device to Repel Xoanon's Creatures

The Doctor activates and positions the squat cylinder outside the village perimeter, humming steadily as it emits a low-frequency vibration and faint blue glow from vacuum tubes. The device functions as a signal barrier intended to block external creatures, but its activation and subsequent discussion reveal its critical flaw when Leela questions the immunity of all forms of energy to the barrier.

Before: Newly constructed and untested, resting inert on damp ground with copper coils and glowing tubes disassembled and jury-rigged.
After: Activated and humming, glowing faintly but emitting no discernible effect on external creatures; its signals are still vulnerable to internal infiltration by Xoanon’s voice.
Sin's Knife

Leela uses her knife to sharpen against a rock outside the village, the metallic scrape echoing in the tense silence. Although primarily a personal tool, its presence underscores her readiness for combat and her need for reassurance in the face of uncertainty. The knife becomes a symbol of her independence and pragmatic assessment of danger.

Before: Unsharpened and dull, carried at Leela’s belt as a standard Sevateem warrior’s blade.
After: Sharpened to a fine edge on a flat rock during conversation, now gleaming and ready for use.
