Vana reveals the acid plan

In the unstable Learning Hall, Selris confronts Vana about her presence, expecting her to have fled to the hills with the others. Vana reveals she and Thara stayed behind with Beta to prepare sulphuric acid—a weapon against the Krotons—intending to deliver it to the Doctor. The exchange exposes the crew’s fractured priorities: while Selris prioritizes survival and escape, Vana and Thara have defied his authority to execute the Doctor’s plan, assuming he is trapped underground with the digging party. The tension underscores the crew’s vulnerability without the Doctor’s guidance, as the Krotons’ threat looms and the Gonds’ leadership remains divided between Selris’s loyalty to the Doctor and Eelek’s pragmatic betrayal. The revelation of the acid’s preparation foreshadows its critical role in the final confrontation, while Vana’s defiance hints at the crew’s growing independence from Selris’s command.

Who Was There

Characters present in this moment

5
Vana
primary

Determined but weary, with a hint of defiance beneath her calm exterior. She is unapologetic about her actions, though the weight of the situation—Selris’s disapproval and the Doctor’s presumed entrapment—lingers beneath her composed demeanor.

Vana stands firm in the unstable Learning Hall, her posture defiant yet weary, as she reveals her and Thara’s decision to stay behind with Beta. She speaks with quiet resolve, her voice steady despite the dust and debris settling around them. Her admission—‘We were bringing it here for the Doctor’—hints at her loyalty to the Doctor’s plan, even as she acknowledges the earthquake’s disruption. Her presence here, rather than in the hills, signals her growing independence from Selris’s authority, aligning her with Thara’s rebellious spirit.

Goals in this moment
  • To justify her and Thara’s decision to stay and prepare the acid, despite Selris’s expectations.
  • To reassure Selris (and herself) that the Doctor is still alive and that their efforts are not in vain.
Active beliefs
  • That the Doctor’s plan to use the acid against the Krotons is the right course of action, even if it means defying Selris.
  • That the Gonds must take proactive steps to fight the Krotons, rather than merely surviving or fleeing.
Character traits
Defiant Loyal to the Doctor’s mission Proactive under pressure Quietly resolute Independent thinker
Follow Vana's journey

Conflicted—partly relieved to see Vana safe, but deeply frustrated by her defiance and the implied challenge to his leadership. His concern for the Doctor borders on desperation, as the Doctor’s absence leaves a critical void in their strategy against the Krotons.

Selris enters the scene already agitated, his voice sharp with concern as he questions Vana’s presence. His focus shifts rapidly from her safety to the Doctor’s whereabouts, revealing his dual role as both a protective leader and a strategist reliant on the Doctor’s guidance. The mention of the Doctor being ‘buried down there’ deepens his unease, as his authority is undermined by the absence of the one outsider who has consistently outmaneuvered the Krotons. His body language—likely tense, with gestures toward the unstable ceiling—reflects his growing frustration with the Gonds’ fractured leadership.

Goals in this moment
  • To ensure Vana’s safety and understand why she disobeyed his orders to flee to the hills.
  • To locate the Doctor and confirm his survival, as his presence is essential to their plan.
Active beliefs
  • That the Gonds’ survival depends on cautious, unified action under his leadership.
  • That the Doctor’s knowledge and technology are irreplaceable in their fight against the Krotons.
Character traits
Protective (of his people, especially Vana) Strategic and reliant on the Doctor’s expertise Frustrated by defiance (Vana’s and Thara’s) Anxious about the Doctor’s safety Authoritative but increasingly uncertain
Follow The Second …'s journey
Supporting 3

Inferred as focused and possibly anxious, given the urgency of their task and the earthquake’s interference. His absence suggests he is likely still engaged in the acid production, prioritizing the mission over personal safety.

Beta is mentioned indirectly by Vana as having collaborated with her and Thara to prepare the acid. Like Thara, his physical absence is notable, but his involvement is critical—his scientific knowledge likely made the acid production possible. His role here is functional: without him, the weapon would not exist. The earthquake’s disruption implies he may still be working on the acid, undeterred by the chaos.

Goals in this moment
  • To successfully produce and deliver the sulphuric acid to the Doctor, despite the earthquake’s setbacks.
  • To support Thara’s leadership and defiance of Selris’s more cautious approach.
Active beliefs
  • That the Gonds’ technological independence is key to their freedom from the Krotons.
  • That the Doctor’s strategies, when combined with Gond ingenuity, can overcome Kroton dominance.
Character traits
Scientifically skilled Loyal to the Gond cause Pragmatic and resourceful Supportive of Thara’s leadership
Follow Beta Dalek's journey

Not directly observable, but inferred as determined and resourceful. If trapped, he is likely already devising a way to escape and rejoin the crew, unaware of the acid’s preparation or the fracture in Gond leadership.

The Doctor is referenced by both Selris and Vana as being ‘buried down there with the digging party,’ presumed trapped underground after the earthquake. His absence is a critical void in the scene—Selris’s concern for him reveals the Doctor’s pivotal role in the Gonds’ strategy, while Vana’s mention of the acid’s intended delivery to him underscores the crew’s reliance on his leadership. The Doctor’s presumed entrapment raises the stakes, as the Gonds’ plan hinges on his guidance and the acid’s effectiveness.

Goals in this moment
  • To escape the underground collapse and rejoin the crew to execute the plan against the Krotons.
  • To ensure the sulphuric acid is used effectively against the Krotons’ power source.
Active beliefs
  • That the Krotons’ power source can be neutralized through a combination of Gond ingenuity and Time Lord technology.
  • That the Gonds’ freedom requires both defiance and strategic precision.
Character traits
Essential to the Gonds’ strategy Reliant on by the crew for leadership and innovation Symbol of hope and expertise
Follow Selris's journey
Thara
secondary

Not directly observable, but inferred as determined and possibly frustrated by Selris’s caution. His absence suggests he is likely focused on the acid production, undeterred by the earthquake or Selris’s disapproval.

Thara is mentioned indirectly by Vana as having stayed behind with her and Beta to prepare the acid. Though physically absent from this exchange, his presence looms large—his rebellious influence is evident in Vana’s defiance, and his absence raises questions about where he is now (likely still with Beta, continuing their work). His role in this event is symbolic: a catalyst for Vana’s actions and a point of tension with Selris, whose authority Thara has repeatedly challenged.

Goals in this moment
  • To continue preparing the sulphuric acid as a weapon against the Krotons, regardless of Selris’s orders.
  • To prove that direct action (like sabotage) is more effective than Selris’s strategic caution.
Active beliefs
  • That the Gonds must take bold, immediate action to free themselves from Kroton rule.
  • That the Doctor’s plan is the most viable path to victory, even if it requires defying Selris.
Character traits
Rebellious Proactive in defiance of authority Loyal to the Doctor’s cause Symbolic figure of Gond resistance

Gonds' Sulphuric Acid Sabotage Weapon

The sulphuric acid, prepared by Vana, Thara, and Beta, is the linchpin of this event. Though not physically present in the scene, its existence is revealed through Vana’s dialogue—‘We were bringing it here for the Doctor’—and its role as a weapon against the Krotons is implicitly critical. The acid’s preparation symbolizes the Gonds’ shift from passive survival to active rebellion, driven by the Doctor’s influence. Its mention foreshadows its later use in the final confrontation, where it will melt the Krotons’ tellurium core. The earthquake’s disruption hints at the fragility of their plan, raising tension around whether the acid will reach the Doctor in time.

Before: Partially prepared by Vana, Thara, and Beta, likely …

Before: Partially prepared by Vana, Thara, and Beta, likely stored in containers at Beta’s house or a hidden location. Its production was interrupted by the earthquake, leaving its completion and delivery uncertain.
After: Still in a precarious state—likely undelivered to the Doctor due to the earthquake, but its existence is now known to Selris, who may either support or hinder its use. The acid remains a critical but vulnerable asset in the Gonds’ arsenal.

Learning Hall (Gond Ceremonial & Educational Chamber)

The Learning Hall, once a ceremonial and educational space controlled by the Krotons, now serves as a tense meeting ground for the fractured Gond leadership. Its crumbling state—‘dust hangs thick’ and the ceiling is unstable—mirrors the Gonds’ precarious position. The hall’s symbolic role as a site of Kroton oppression is inverted here: instead of being a place of subjugation, it becomes a refuge for rebels like Vana, who defies Selris’s authority. The location’s atmosphere is charged with urgency and conflict, as Selris’s confrontation with Vana exposes the divide between survival and rebellion. The hall’s physical decay also foreshadows the impending collapse of Kroton rule, should the Gonds’ plan succeed.

Dust hanging thick in the air, settling on surfaces and figures. Unstable ceiling, with debris crashing down intermittently. Faint humming or vibrations from the Krotons’ nearby machinery, adding to the tension. Dim, uneven lighting, casting long shadows and highlighting the hall’s decay.
Under Hall

The Under Hall, though not the primary setting of this event, is referenced indirectly through Vana’s mention of the ‘earthquake’ that interrupted their plan to deliver the acid. This location—partially collapsed and unstable—serves as a backdrop to the broader chaos unfolding. While Selris and Vana are in the Learning Hall, the Under Hall’s presence looms as a reminder of the immediate dangers the crew faces, from structural collapse to the Krotons’ advancing machinery. The earthquake’s disruption implies that the Under Hall may have been the site of the digging party’s entrapment, where the Doctor is presumed buried.
