S12E10 · The Sontaran Experiment Part 2

Styre crushes Vural under deadly gravity

Styre escalates the gravity experiment to a lethal 600 pounds, crushing Vural beneath the unrelenting force. As Vural gasps for air and Krans and Erak strain to hold the weight aloft, the Doctor intervenes with a strategic taunt to lure Styre away from his instrument of torture. The Doctor’s challenge to single combat distracts the Sontaran warlord just long enough for Sarah and Harry to free Vural and disrupt the experiment’s cruel rhythm. The gravity’s crushing pressure becomes a metaphor for the Sontaran’s brutal assessment of human endurance, a test designed to break bodies before an invasion breaks worlds. key_dialogue: [ STYRE: Increase to six hundred pounds. DOCTOR: Styre! STYRE: You? But I killed you. ]

Who Was There

Characters present in this moment

5

Overwhelmed by adrenaline, his dry wit momentarily silenced by the life-or-death stakes pressing down on the three of them.

Harry, still clutching Jellicoe’s screwdriver, hesitates before surrendering it to the Doctor, then acts immediately when the gravity crisis erupts. He joins Sarah at the experiment, pushing with mechanical precision and naval-trained endurance to lift the bar high enough to roll Vural free. His scepticism turns to grim cooperation as he uses primitive tools and sheer grit to undo Sontaran engineering.

Goals in this moment
  • support Sarah in physically saving Vural
  • enable the Doctor’s distraction tactic by staying out of immediate danger
Active beliefs
  • the Doctor knows what he’s doing even when it seems reckless
  • force must be met with force when innocents are at risk
Character traits
reluctant but decisive under fire resourceful with limited tools pitching in despite lack of combat experience following the Doctor’s instructions with scant protest
Follow Harry Sullivan's journey
Krans
primary

Raw determinism straining at the edge of collapse, teetering between triumph and total physical breakdown.

Krans and Erak brace beneath the massive gravity bar, their arms shaking as Styre orders the weight raised to lethal levels. Veins bulge in their necks and sweat pours down their faces. When the Doctor’s challenge distracts Styre, they use the moment to tip the bar sideways, rolling Vural free from the crushing mechanism. Their resolve cracks as they collapse momentarily once pressure is off, but their posture immediately shifts to wary relief.

Goals in this moment
  • prevent Vural’s death by any means necessary
  • survive the experiment long enough to help others
Active beliefs
  • human resistance still matters even against Sontaran technology
  • every second counts when facing extinction
Character traits
exhausted strength relentless loyalty to fellow captives pragmatic survival instinct visceral resentment of Styre
Follow Krans's journey

Fierce urgency with growing anger at Styre’s cruelty, trembling with adrenaline as she fights to reverse the experiment’s fatal logic.

Sarah sprints from the Doctor’s side toward the gravity experiment the moment she sees the command given to increase weight. She rushes to help Krans and Erak lift the bar just enough to pull Vural from beneath it. Her hands slip on the greasy metal as she pushes with raw effort, shouting encouragement while coordinating with Harry to break the machine’s rhythm.

Goals in this moment
  • free Vural from the gravity bar before he suffocates
  • disrupt Styre’s psychological dominance over the captive humans
Active beliefs
  • even the weakest among them deserve a chance to live
  • the Doctor’s plan will work if they move fast
Character traits
pragmatic ally under pressure quick to action despite fear determined to save a fellow captive vocally supportive of Harry
Follow Sarah Smith …'s journey

Initially composed and commanding, then boiling into offended rage that clouds judgment—momentarily abandoning strategy for honour.

Field Major Styre stands over the gravity experiment, commanding the inexorable rise of the bar through his translator while Krans and Erak struggle beneath its mass. He remains clinically detached even as Vural’s suffering becomes audible. When the Doctor appears and challenges him, Styre’s cold logic shatters into blind fury: he drops his rifle, seizes a combat knife, and duels the Time Lord in a mockery of Sontaran martial pride. He fights with brutal precision but cannot land a blow on the nimble Doctor.

Goals in this moment
  • complete the gravity assessment to determine human viability
  • proove Sontaran dominance through ritual combat
Active beliefs
  • human physiology is inherently inferior and must be measured accordingly
  • a true Sontaran warrior never refuses a challenge on principle
Character traits
ruthlessly methodical suddenly impulsive when challenged dogmatic about Sontaran superiority physically strong but earth-gravity hampered
Follow Styre's journey
Supporting 1
Vural
secondary

Desperate suffocation melting into dazed relief as pressure releases, his survival instinct momentarily triumphing over pain and shame.

Vural lies pinned beneath the gravity bar, his body trembling under the escalating force as Styre orders the weight to six hundred pounds. His breath comes in shallow gasps through clenched teeth as Krans and Erak struggle to hold the bar just inches above his collapsing ribcage. When Sarah and Harry manage to lift the bar slightly, Vural coughs violently, half-conscious and gasping for life-saving air.

Goals in this moment
  • breathe despite crushed ribs and collapsing lungs
  • survive long enough to see Styre’s departure
Active beliefs
  • the end has come unless someone intervenes
  • any mercy is a gift beyond expectation
Character traits
broken but not defeated physically shattered by torture displaying pathetic gratitude when relieved unable to speak clearly, only groan or nod
Follow Vural's journey

Earth Men's Combat Knives

Earth Men's Combat Knives are carried by human prisoners, including Harry, pulled from belts or pockets when needed. Styre seizes one during the duel, wielding it with Sontaran-sized hands in ill-suited but committed strokes against the Doctor. The knife’s chipped edge and frayed grip bear witness to its prior use in failed uprisings—now redeployed in a desperate fencing match that decides life or death.

Before: Crudely sheathed in prisoners’ belts or lying near the gravity rig, unnoticed until Styre draws one in response to the Doctor’s challenge.
After: Dropped to the cavern floor after Styre’s weapon is stripped away, the blade dull from repeated clashes but its symbolic victory intact—the Doctor has forced a Sontaran to fight on human terms.
Harry's Improvised Rescue Stick

Harry’s Improvised Rescue Stick is seized by the Doctor at the start of the sequence and wielded as a mock Sontaran weapon in the duel with Styre. Though it never strikes flesh, the stick’s primitive heft becomes a tool of psychological warfare, clashing against Styre’s combat knife in feints and parries. It embodies human improvisation against Sontaran martial ritual, its bark scuffed by nervous grip as it channels the Doctor’s audacious plan.

Before: Resting against the cavern wall or in Harry’s possession as a makeshift walking aid.
After: Passed to the Doctor, who uses it in the staged fencing match before abandoning it in the dust as Styre drops his own weapon and the Doctor takes up a combat knife.
Jellicoe's Sabotage Screwdriver

Jellicoe’s Adjustment Screwdriver, handed to Harry by the Doctor moments before the gravity crisis erupts, becomes an instrument of misdirection rather than direct sabotage in this event. The Doctor uses it not to break the gravity device but to transfer Harry’s attention away from action and toward the rescue effort. Its presence symbolizes human ingenuity repurposed under alien duress.

Before: In Harry’s possession, given by the Doctor with …
After: Still in Harry’s hand or pocket as he …
Before: In Harry’s possession, given by the Doctor with tacit instructions.
After: Still in Harry’s hand or pocket as he rushes to help free Vural. Its metal head remains cool and unmarred, unused directly against Sontaran tech during this confrontation.
Styre's Sontaran Gravity Field Weapon

Styre’s Sontaran Gravity Field Weapon is not a handheld device in this moment but rather represented by the immense mechanical gravity bar itself, which he controls remotely to inflict crushing force. As he orders the weight increased to six hundred pounds, the weapon’s function becomes purely visceral: it is used to test, measure, and destroy human endurance. Its calibrated increments, marked in fifty-pound steps and etched with prior victims’ screams, underscore Sontaran clinical sadism.

Before: Resting on Vural’s chest at approximately 550 pounds, …
After: Bar slams to the cavern floor or is …
Before: Resting on Vural’s chest at approximately 550 pounds, held at that level by Krans and Erak under Styre’s orders.
After: Bar slams to the cavern floor or is tilted aside as pressure is removed, freeing Vural’s crushed torso. It remains in place as the Doctor lures Styre away, the machine still humming with residual energy.

Hound Tor Interior Prison Caves (Prison Complex)

The Tor Caves compress the horror of Styre’s experiments into a jagged, echoing chamber where rock itself seems to press down on the living. The gravity rig stands bolted to the cavern floor, its steel bar a skeletal shadow over the broken bodies beneath. Sontaran equipment glows with clinical blue light, turning the air metallic and the shadows long. As Styre orders the weight increased, the cave groans under the strain—not just of metal and rock, but of human endurance.

Sontaran Empire

The Sontaran Empire is represented in this moment by Field Major Styre executing its doctrine of invasive assessment: human specimens are tortured to determine physiological weaknesses before planetary invasion. His command to increase to six hundred pounds is an operational violence ordered with complete detachment, typical of Sontaran military protocol. By abandoning his pulse rifle and accepting the Doctor’s challenge to personal combat, Styre upholds Sontaran pride even as it thwarts operational efficiency.
