Confusion and physical debilitation following the sudden severing of psychic control

Tegan staggers forward but collapses moments after her bracelet’s powerpack is wrenched free by the Doctor. Vertigo and sudden freedom leave her disoriented; she makes no coherent attempt to move as the Doctor checks her over, her only sound the frustrated noise of a person cut off mid-rush by forces beyond her control.

  • Reassert agency despite vertigo and disorientation
  • Regain clear equilibrium to continue resisting the Terileptils
Active beliefs
  • The Doctor’s actions restore immediate safety

Surprise and lingering anxiety after the psychic shackles vanish

Mace receives the powerpack’s energy through his pistol and reels back with a cry. When the Doctor removes the device still latched inside his bracelet, Mace recoils, voice shaking as he demands to know how the Doctor can promise safety. The swagger of earlier has evaporated under residual pain and fear.

Goals in this moment
  • Understand what just happened and regain composure
  • Reassess the Doctor’s reliability in the face of sudden physical distress
Active beliefs
  • The Doctor’s assurances require skeptical verification
  • Control once lost is not easily trusted even when severed

Mace's Conduit Tool (Transformed Pistol)

Mace’s Conduit Pistol briefly becomes the channel for the powerpack’s unstable energy as the Doctor presses the second pack’s vent against its shroud. The polymer frame groans under voltage as volts arc violently between the barrel’s vents and the pack’s seams, forcing Mace to endure the current before the Doctor wrenches the pack away.

Before: Functioning sidearm carried by Mace; plastic frame intact …
After: Partially overloaded, groaning under residual stress; no longer …
Before: Functioning sidearm carried by Mace; plastic frame intact but now adopted as an improvised conductor
After: Partially overloaded, groaning under residual stress; no longer serving as conduit once the pack is removed
Mace's Polygrite Bracelet

Tegan’s Polygrite bracelet is pried open by the Doctor and the embedded Terileptil powerpack torn out in one movement. The alien metal’s glyphs gutter as control drains, and the bangle falls slack around her wrist, its cold bite replaced by sudden exposure to freedom. The sudden void leaves Tegan collapsed and disoriented.

Before: Fastened securely around Tegan’s wrist, housing the Terileptil …
After: Loosened and exposed; its alien glyphs dimmed and …
Before: Fastened securely around Tegan’s wrist, housing the Terileptil powerpack and relaying control impulses
After: Loosened and exposed; its alien glyphs dimmed and its purpose terminated with the removal of the powerpack
Second Terileptil Powerpack

The Doctor seizes the second Terileptil powerpack from Mace’s pistol vent by twisting it free, immediately discharging its unstable energy through the weapon’s conduit before violently kicking the spent device across the cell floor. He then extracts Tegan’s equivalent from her bracelet, severing the psychic link that had compelled the pair. Its crimson glow fades as it leaves the circuit, leaving behind only residual violet sparks.

Before: Actively embedded in Tegan’s Polygrite bracelet and fused …
After: Spent, discarded, and inert; its green energy dissipated …
Before: Actively embedded in Tegan’s Polygrite bracelet and fused into Mace’s pistol; radiating faint organic green glow while controlling its hosts
After: Spent, discarded, and inert; its green energy dissipated into the cell’s air as brief violet sparks

Terileptil Interrogation Cell

The claustrophobic interrogation cell confines the trio within damp stone walls sloping inward, forcing shoulders-to-shoulders proximity during the procedure. The corroded iron grilles in the door frame cast jagged shadows, amplifying the metallic tang of manacles that still cling to the crumbling ledge. Emergency lighting flickers fitfully around Tegan’s collapse and Mace’s recoil, while pooled water rustles toward the central drain, underscoring both their entrapment and the fragility of their recent deliverance.
