S12E10 · The Sontaran Experiment Part 2

Doctor comprehends Sontaran experiment design

Harry returns to find Sarah and the Doctor unconscious in the cavernous Hound Tor interior. Styre’s arrival forces Harry into hiding as the Sontaran Field Major delivers a chilling overview of his human experiments, documenting critical weaknesses in human physiology—fluid dependence and gravity tolerance—that would inform a Sontaran invasion strategy. The Doctor, having recovered by secreting a synesthetic lock component from the Nerva Beacon, quietly dissuades Harry from rash action and insists on analyzing Styre’s motives. Observing further atrocities, the Doctor resolves to dismantle the experiment and its larger purpose before a full-scale assault can commence, heightening the urgency of their precarious position. key_dialogue: [ DOCTOR: Never throw anything away, Harry. Where's my five hundred year diary? I remember jotting some notes on the Sontarans. It's a mistake to clutter one's pockets, Harry. ]

Who Was There

Characters present in this moment

7

Focused detachment; his humor masks intense observation and calculation, as he prioritizes mission success over emotional reaction.

The Doctor awakens, having concealed a synesthetic locking mechanism fragment from the Nerva Beacon. Observing Styre’s experiments, he physically restrains Harry and redirects him from immediate retaliation, emphasizing strategic analysis over impulsive action. He then departs to investigate the broader context of the experiment, signaling tactical disengagement from the cavernous chamber.

Goals in this moment
  • Prevent Harry from endangering both the group and the mission through rash action.
  • Determine the motive behind Styre’s experiments in order to dismantle them effectively.
Active beliefs
  • Human suffering must be mitigated, even at the cost of direct confrontation.
  • Understanding the enemy’s logic is essential to countering their strategy.
Character traits
strategic calm under pressure experienced improvisational
Follow The Fourth …'s journey
Roth
primary

Distraught and anxious, oscillating between grief over Roth’s death and urgent worry for Sarah’s wellbeing; his instinct to act clashes with the Doctor’s strategic guidance.

Harry Sullivan scrambles down the rocky cavern interior to check on the Doctor and Sarah, only to collapse from exhaustion. He grasps his improvised weapon and observes Roth’s corpse before hiding in the shadows as Styre approaches. Confronted by the Doctor’s restraint and explanation, his concern for Sarah fuels a mix of distress and resolve.

Goals in this moment
  • Ensure the safety of Sarah and the Doctor.
  • Confront Styre and the Sontarans responsible for these experiments.
Active beliefs
  • Human life must be protected at all costs.
  • Action is necessary even in desperate circumstances.
Character traits
heroic pragmatic viscerally reactive loyal to allies
Follow Roth's journey

Composed confidence masking a larger strategic impatience; his tone and posture register no empathy, only cold validation of Sontaran superiority.

Field Major Styre strides deliberately into Roth’s alcove to inspect the dead human subject, reviewing experimental findings aloud with cold precision. He commands Erak and Krans to increase the gravity bar’s weight over Vural, demonstrating absolute control over both the environment and human lives, indifferent to their pain or terror.

Goals in this moment
  • Document human physiological weaknesses to streamline invasion planning.
  • Maintain dominance over captive subjects and any potential interference through calculated demonstrations of power.
Active beliefs
  • Human life is subordinate to Sontaran strategic objectives.
  • Rigorous documentation of human failings ensures the success of future conquests.
Character traits
ruthless methodical authoritative militaristically detached

Supporting 4
Erak
secondary

Strained with resentment and fear, trapped between their duty to survive and the moral horror of their actions—each increment of pressure another violation etched into memory.

Erak stands alongside Krans, both forced to sustain the crushing weight of the gravity bar over Vural’s body, operating the mechanism to increase pressure at Styre’s order. Their physical involvement mirrors their shared desperation and constrained agency under Sontaran duress.

Goals in this moment
  • Execute Styre’s orders to avoid personal harm.
  • Minimize additional injuries to Vural without endangering themselves.
Active beliefs
  • Survival requires compliance, even when the task is monstrous.
  • Humanity must retain some sense of solidarity against the invader.
Character traits
reluctantly cooperative physically taxed tense under coercion
Follow Erak's journey
Krans
secondary

Desperate resistance buried beneath fear of the Sontaran’s retaliatory violence; dread of the immediate act weighs heavily upon him.

Krans is forcibly positioned holding a portion of the gravity experimental apparatus over Vural’s prone body. Enforcing Styre’s command, he participates in the brutal act, his physical compliance masking deep inner distress and resentment toward the task.

Goals in this moment
  • Survive the immediate threat posed by Styre.
  • Limit harm to Vural without attracting additional punishment.
Active beliefs
  • Resistance is survival, but overt defiance is suicide.
  • Collaboration, however painful, may be the only path to staying alive.
Character traits
resistant but compliant physically strained suppressed anger
Follow Krans's journey
Vural
secondary

Desperate panic rapidly curdling into resignation and pain as each increase in pressure threatens to crush him; survival hinges on sheer endurance rather than hope.

Vural is restrained and pinned beneath the massive gravity weight, enduring escalating pressure as the weight is raised to hundreds of pounds at Styre’s command. His desperate physical state and panicked pleas underscore the insufferable cruelty of the experiment.

Goals in this moment
  • Survive the immediate application of crushing force.
  • Resist psychological collapse under the weight of Sontaran cruelty.
Active beliefs
  • No rescue is coming; only endurance and luck offer survival.
  • Resistance under such duress is futile, so silence and compliance are the only tools left.
Character traits
terrified physically broken defenseless
Follow Vural's journey

Unconscious and thus free of immediate emotional response; her later revival will ground the counteroffensive.

Sarah lies unconscious across the cavernous interior of Hound Tor, unaware of the unfolding atrocities and the presence of Styre. Her inert state renders her directly affected but not actively participating in this moment, though her condition catalyzes the urgency of the Doctor’s intervention.

Gravity Experimental Bar

The Gravity Experimental Bar becomes a lethal device as Harry and the Doctor observe from concealment, with its weight escalating from forty to three hundred pounds under Styre’s command. Its metallic mass looms over Vural, threatening to crush his body beneath the crushing load.

Before: Mounted and calibrated as part of Styre’s torture apparatus.
After: Remains under direct Sontaran control, continuing to serve as an instrument of psychological and physical terror.
Gravity Regulation Control Pad

The Gravity Experiment Control Pad functions as Styre’s tool for adjusting the intensity of the gravity bar experiment over Erak, Krans, and Vural. Each press of the pad increases the weight suspended above them, transforming the bar into a living instrument of torture.
