Who Was There
Characters present in this moment
Frustration and resignation, masking vulnerability beneath a facade of stern control
Stevenson stands with weapon drawn, torn between duty and humanity, defending his lethal decision as a grim necessity. He eventually yields to the Doctor’s insistence but shifts blame to maintain command, revealing the erosion of empathy under institutional pressure.
- • Protect the station by any means necessary, even if it means sacrificing infected individuals.
- • Maintain operational discipline and perceived authority in the face of collapsing morale.
- • That certain losses are required to prevent total disaster.
- • That protocol and hierarchy must be enforced regardless of individual suffering.
Steely resolve masking underlying urgency, with flashes of exasperation at Kellman’s manipulation
The Doctor vigorously interposes himself between Stevenson and Warner, demanding the infected man receive treatment rather than be executed. He asserts his dual authority as both a Time Lord and a medical practitioner, positioning himself as both challenger of authority and healer.
- • Prevent the killing of an infected—but salvageable—crewman to uphold ethical and medical duty.
- • Assert medical and scientific authority to shift control from panicked command to expert intervention.
- • That no life should be ended solely out of fear of infection, even in extremis.
- • That scientific reasoning and expert analysis can outperform fear-based policy.
Cool calculation masking glee at fomenting chaos and advancing his covert agenda
Kellman exploits the crisis to manipulate both Stevenson and the Doctor, steering blame toward the newcomers and escalating paranoia. He delivers a calculated condemnation of the Doctor’s team and exits abruptly to undermine potential trust, deepening the atmosphere of betrayal.
- • Widen suspicion within the station to conceal his own collusion with external forces.
- • Force Stevenson and the crew into more desperate, self-destructive actions by inflaming fear.
- • That chaos is an opportunity to reshape control.
- • That truth is irrelevant compared to leveraging fear for personal or factional gain.
Growing moral indignation and determination to prevent injustice under the guise of quarantine
Sarah questions the flawed logic of Stevenson and Lester, exposing the contradiction in their accusations and lending critical rational support to the Doctor’s intervention. She then physically aids in removing the patient, embodying both skepticism and active compassion.
- • Challenge irrational decisions that threaten human life and justice.
- • Support the Doctor’s medical mission by ensuring the patient is moved to appropriate care.
- • Expose Kellman’s insidious influence through logical rebuttal.
- • That no one should be killed without proof and due process.
- • That truth and compassion must be upheld, even in crisis.
Pragmatic confidence in medical training, masking unease at the station’s descent into hysteria
Harry assists in carrying the infected crewman out of the control room and reassures the Doctor that their team has had no contact with the plague. He reinforces the medical team’s credibility and aids in the physical removal of the patient, grounding the group’s response in clinical detachment.
- • Ensure the infected man receives isolated care rather than execution.
- • Validate the Doctor’s authority and debunk the plague transmission fears infecting the crew.
- • Provide medical assistance while maintaining sterile protocols.
- • That scientific knowledge can counteract irrational fear.
- • That proper triage and isolation are superior to lethal containment.
Desperate pragmatism tinged with guilt over the crew’s suffering
Lester aids the Doctor in carrying Warner to safety despite believing his condition is nearly fatal. His actions reflect grim acceptance and resignation to the inevitability of loss, even as he assists the opposing medical intervention.
- • Preserve whatever life remains and mitigate futile suffering amid the plague.
- • Support authority figures while privately questioning their decisions.
- • That some measures must be taken to delay the spread, even if ultimately ineffective.
- • That questioning command could endanger unit cohesion and safety.
