Who Was There
Characters present in this moment
Initially concerned for Polly’s safety, then panicked as the fumes overwhelm them both, and finally disoriented and wary as he recovers under the colony’s care—his distrust of the Doctor deepens with the wink, suggesting a growing rift between them.
Ben, separated from the Doctor, explores the Mercury Swamp with Polly but quickly recognizes the danger of the mercury fumes. He warns Polly not to touch the pools, but she is caught in a cloud of fumes, coughing violently. Ben tries to drag her to safety, but the fumes overwhelm him as well, and he collapses unconscious. Later, he recovers under the care of Bragen and Quinn, coughing and disoriented. His interactions with the colony leaders reveal his wariness and protective instincts, especially toward Polly, and his growing suspicion of the Doctor’s motives (noticed in the Doctor’s cryptic wink).
- • Protect Polly from the mercury fumes at all costs (dragging her to safety).
- • Survive the toxic environment and recover his strength (collapsing but later reviving).
- • Assess the colony’s intentions and the Doctor’s deception (noticing the wink and Bragen’s suspicions).
- • The Doctor is hiding something (distrust deepens with the wink).
- • The colony’s leaders cannot be fully trusted (wary of Bragen and Quinn’s motives).
- • Polly’s safety is his top priority, even in an unfamiliar and hostile environment.
Initially curious and alarmed by the swamp’s beauty, then horrified as the fumes overwhelm her, and finally incapacitated and dependent on others for survival—her recovery is marked by disorientation and a growing awareness of the colony’s dangers.
Polly, curious and empathetic, explores the Mercury Swamp with Ben but is quickly overcome by the mercury fumes. She coughs violently as the fumes seep into her lungs, and Ben tries to drag her to safety, but she collapses unconscious. Later, she is found by Bragen and Quinn’s guards and carried to safety. Her incapacitation underscores the swamp’s lethality and the colony’s neglect of basic safety measures, while her recovery under the colony’s care introduces the leadership’s mixed motives (concern for her well-being vs. suspicion of outsiders).
- • Explore the swamp safely (trusting Ben’s guidance but underestimating the fumes’ danger).
- • Survive the toxic environment (collapsing but later revived by the colony’s guards).
- • Assess the colony’s intentions (recovering under Bragen and Quinn’s care, observing their dynamics).
- • The Doctor and Ben can be trusted to guide her, though the environment is unpredictable.
- • The colony’s leaders may have hidden motives (noticed in Bragen’s suspicions and Quinn’s pragmatism).
- • Safety in this environment requires constant vigilance (learned from the fumes’ sudden attack).
Suspicious and authoritative—his tone is accusatory toward the Doctor (Examiner) and defensive about the colony’s operations. He is curious about the Examiner’s unexpected arrival but prioritizes maintaining control over the situation, masking any deeper unease about the ambush or the Doctor’s true identity.
Bragen arrives with Quinn to discover the unconscious Doctor, Ben, and Polly by the mercury pools. He questions the Doctor’s (Examiner’s) presence, suspects foul play, and orders his guards to carry the victims back to the colony. His interactions with Quinn reveal his authoritarian and suspicious nature, as well as his awareness of the colony’s secrets (e.g., Lesterson’s capsule). His role as Head of Security is central to the colony’s control, and his arrival marks the transition from the ambush to the colony’s intervention.
- • Determine the Doctor’s (Examiner’s) true identity and motives (questioning him and noting the bruise).
- • Maintain control over the colony’s secrets (preventing Earth’s inspection, as implied by his suspicion of the Examiner).
- • Ensure the safety of the victims (ordering guards to carry them back to the colony).
- • The Examiner’s arrival is unexpected and potentially threatening (suspicious of Earth’s motives).
- • The Doctor is hiding something (noticing the bruise and questioning his story).
- • The colony’s security is his responsibility, and outsiders must be closely monitored (authoritarian stance).
None (deceased), but his arrival and death evoke tension and foreshadow the colony’s secrets and the Doctor’s deception.
The Examiner arrives in the clearing, announcing his presence, but is immediately shot and killed by the white-suited figure. His body is dragged away, and his badge is taken by the Doctor, who uses it to impersonate him. The Examiner’s sudden death introduces the colony’s hidden violence and the Doctor’s willingness to deceive, while his absence leaves a void that the Doctor fills with calculated manipulation.
- • None (killed upon arrival), but his presence would have been to inspect the colony’s operations (implied by Bragen’s later suspicion).
- • Represent Earth’s authority (his badge becomes a tool for the Doctor’s impersonation).
- • The colony is operating within Earth’s regulations (his unannounced arrival suggests otherwise).
- • His inspection would uncover the truth about Lesterson’s capsule (his death prevents this).
Concerned and pragmatic—his tone is diplomatic and empathetic, though his curiosity about the Examiner’s arrival hints at deeper awareness of the colony’s tensions. He is less suspicious than Bragen but equally invested in uncovering the truth, masking any personal stakes in the outcome.
Quinn, as Deputy Governor, assists in carrying the unconscious Doctor and Polly, challenging Bragen’s suspicions and ordering the guards to help. He introduces himself to Ben, expressing concern for their well-being, and engages in a pragmatic exchange with Bragen about the Examiner’s arrival. His role as a diplomatic counterbalance to Bragen’s authoritarianism is evident, though his own motives remain ambiguous. His care for the victims suggests a more empathetic approach to leadership, but his awareness of the colony’s secrets is implied by his questions about the Examiner.
- • Ensure the safety and recovery of the victims (ordering guards to carry them back).
- • Challenge Bragen’s authoritarianism and suspicions (diplomatic counterbalance).
- • Uncover the truth about the Examiner’s arrival (questioning Bragen and observing the Doctor).
- • The colony’s leadership must balance security with compassion (contrasting with Bragen).
- • The Examiner’s arrival is unusual and warrants investigation (curious but not accusatory).
- • Outsiders like Ben and Polly deserve care, even if their presence is suspicious (empathetic).
Hostile and methodical—no remorse or hesitation, treating the Examiner’s death and the Doctor’s incapacitation as routine tasks. His actions suggest cold operational discipline, with no emotional investment in the victims.
The white-suited figure ambushes the Examiner, killing him with a single shot, then knocks the Doctor unconscious and implants a button in his hand. He drags the Examiner’s body away, leaving the Doctor sprawled on the ground. His actions are methodical and ruthless, revealing the colony’s hidden violence and the Doctor’s vulnerability. The figure’s identity and motives remain unknown, but his role as an enforcer for Bragen’s security forces is implied by his white survival suit and goggles, which match those worn by Bragen and Quinn later in the scene.
- • Eliminate the Examiner to prevent Earth’s inspection of the colony (killing him outright).
- • Incapacitate the Doctor and implant the button, likely to frame him or manipulate the situation (leaving him unconscious with the button).
- • Cover up the ambush by dragging the Examiner’s body away (hiding evidence of the crime).
- • The Examiner’s presence is a threat to the colony’s secrets (must be eliminated).
- • The Doctor is a liability or a target (knocking him unconscious and implanting the button).
- • His actions are justified by Bragen’s orders or the colony’s hidden agenda (loyalty to security forces).
Initially playful and distracted, shifting to horrified upon witnessing the Examiner’s murder, then calculating as he assumes the Examiner’s identity, and finally cryptic with his wink at Ben—masking deeper manipulation and unease about his new body’s vulnerabilities.
The Doctor, distracted by his diary and tape measure, navigates the Mercury Swamp with playful curiosity, leaping over boulders to test his regenerated body’s agility. He avoids mercury pools with apparent obliviousness, only later realizing his own dexterity. His detachment from Ben and Polly’s plight is stark—he is focused on his own experiments and the Examiner’s badge, which he uses to assume the Examiner’s identity. The white-suited figure ambushes him, knocking him unconscious and implanting a button in his hand, leaving him vulnerable and cryptic in his interactions with Bragen and Quinn. His wink at Ben suggests ongoing deception and a hidden agenda.
- • Test the limits of his regenerated body’s physical capabilities (leaping, measuring).
- • Assume the Examiner’s identity to infiltrate the colony and uncover its secrets (taking the badge).
- • Protect Ben and Polly indirectly by manipulating the situation (though his detachment suggests mixed motives).
- • His companions’ safety is secondary to his own investigations (prioritizing the Examiner’s badge over their well-being).
- • The colony’s secrets are worth the risk of deception (willing to impersonate the Examiner).
- • His regenerated body’s agility is a source of fascination and potential advantage (testing it with the boulder leap).
Neutral—they perform their duties without emotional involvement, treating the victims as objects to be transported. Their lack of reaction suggests either indifference or strict adherence to protocol.
Bragen’s guards carry the unconscious Doctor, Ben, and Polly back to the colony as ordered. Their actions are neutral and efficient, reflecting their role as enforcers under Bragen’s command. They do not speak or exhibit independent thought, serving as extensions of the colony’s authority. Their presence underscores the colony’s control over the situation and the victims’ vulnerability.
- • Follow Bragen’s orders to carry the victims back to the colony (obeying commands).
- • Maintain security and control over the situation (neutral enforcement).
- • Their role is to enforce Bragen’s authority without question (loyalty to the colony’s security).
- • The victims are outsiders who must be contained (neutral but firm handling).
Objects Involved
Significant items in this scene
The button is implanted in the Doctor’s hand by the white-suited figure after knocking him unconscious. The button serves as a mysterious and invasive clue, hinting at a larger conspiracy or manipulation by the colony’s security forces. Its implantation suggests that the Doctor is being framed or set up for something, adding a layer of intrigue to his impersonation of the Examiner. The button becomes a symbol of the colony’s hidden control and the Doctor’s unwitting involvement in its schemes.
The Doctor’s diary is used as a tool for investigation, allowing him to consult notes on planetary environments (oxygen density, radiation levels, temperature) to gauge the conditions on Vulcan. While Ben and Polly are poisoned by mercury fumes, the Doctor remains distracted by the diary, measuring and calculating as he leaps over boulders. The diary symbolizes his scientific curiosity and detachment from the immediate danger faced by his companions, highlighting the rift between his investigative focus and their survival.
The TARDIS serves as the Doctor’s transport vessel and a potential refuge for Ben and Polly, though they collapse unconscious near it before the Doctor’s return. The TARDIS’s blue police box exterior contrasts sharply with the toxic swamp, symbolizing the Doctor’s otherworldly origins and the companions’ dependence on his technology. Its presence hints at the possibility of escape, though the Doctor’s focus on the Examiner’s badge and his own experiments delays their use of it as a sanctuary.
The Doctor pulls out his wire-rimmed spectacles in an attempt to read the Examiner’s badge, but his newly regenerated eyes reject the correction, rendering them useless. The spectacles slip off unused, symbolizing his physical adjustment to his new body and the limitations of his past self’s tools. This moment highlights the Doctor’s vulnerability and the disorientation of regeneration, as he struggles to adapt to his changed physiology.
The Examiner’s badge is taken by the Doctor after the Examiner is killed. The badge serves as official identification from Earth, enabling the Doctor to impersonate the Examiner and infiltrate the colony. Its theft is a pivotal act of deception, allowing the Doctor to manipulate Bragen and Quinn while hiding his true identity. The badge symbolizes Earth’s authority, which the Doctor co-opts for his own ends, furthering the narrative’s themes of identity and trust.
The mercury pools and fumes are the primary environmental hazard in the swamp, responsible for poisoning Ben and Polly. The fumes rise from the bubbling pools, catching Polly full in the face and causing her to cough violently. Ben, recognizing the danger too late, tries to drag her to safety but is also overcome. The mercury fumes symbolize the planet’s lethality and the colony’s neglect of basic safety measures, serving as a constant threat to outsiders and a reminder of the Doctor’s detachment from the immediate peril faced by his companions.
The path-obstructing boulder in the Mercury Swamp serves as a test of the Doctor’s regenerated body’s agility. He measures it with his tape measure, then leaps over it with playful precision, demonstrating his physical capabilities. The boulder symbolizes the Doctor’s detachment from the immediate danger faced by Ben and Polly, as he treats the swamp as a personal playground rather than a lethal environment. His interaction with the boulder contrasts sharply with the companions’ suffering, highlighting the growing rift between them.
The Doctor’s tape measure is used to test the height of a boulder blocking his path. He unfurls it, takes measurements, and scribbles calculations in his diary, treating the obstacle as a personal challenge to his regenerated body’s agility. The tape measure symbolizes his playful experimentation and scientific mindset, contrasting sharply with the deadly seriousness of the mercury fumes poisoning Ben and Polly nearby. Its use underscores the Doctor’s detachment from the immediate peril faced by his companions.
The white survival suit, complete with goggles, is worn by the white-suited figure during the ambush. The suit protects the figure from the toxic mercury fumes, allowing him to move freely in the swamp while Ben and Polly are incapacitated. The suit’s bulk and goggles also serve as a disguise, obscuring the figure’s identity and adding to the ambiguity of the attack. When Bragen and Quinn arrive, the figure pushes his goggles up, revealing his face briefly before disappearing, hinting at his connection to the colony’s security forces.
The white-suited figure’s pistol is used to kill the Examiner with a single shot, then as a bludgeon to knock the Doctor unconscious. The weapon is a symbol of the colony’s hidden violence and the white-suited figure’s ruthless efficiency. Its use marks the transition from the Doctor’s playful exploration to the deadly seriousness of the ambush, underscoring the colony’s dangers and the Doctor’s vulnerability. The pistol also serves as a tool of manipulation, as the figure implants the button in the Doctor’s hand before dragging the Examiner’s body away.
The white-suited figure’s goggles are part of his survival suit, pushed up over his head when Bragen and Quinn discover him. The goggles symbolize the figure’s dual role—as a protected enforcer of the colony’s will and as a hidden assassin. Their removal in the presence of Bragen and Quinn suggests a moment of vulnerability or recognition, hinting at his loyalty to the colony’s security forces and the internal dynamics at play.

The TARDIS landing site is a narrow clearing in the Mercury Swamp, where the Doctor’s time machine has settled. Toxic mercury fumes drift across this area, and it is here that Ben and Polly step out to explore, only to be overwhelmed by the fumes and collapse unconscious. The site serves as a threshold between the Doctor’s otherworldly technology and the swamp’s lethal environment, symbolizing the companions’ vulnerability and the Doctor’s detachment. The TARDIS’s presence hints at the possibility of escape, though the Doctor’s focus on the Examiner’s badge and his own experiments delays their use of it as a sanctuary.

The Earth Examiner’s Office is represented in this event by the Examiner himself, whose sudden arrival and murder introduce the colony’s hidden violence and the Doctor’s deception. The Examiner’s badge, taken by the Doctor, becomes a tool for his impersonation, allowing him to infiltrate the colony under the guise of Earth’s authority. The organization’s presence is felt through the Examiner’s unannounced inspection, which sparks suspicion among the colony’s leaders (Bragen and Quinn) and sets the stage for the Doctor’s manipulation of the situation. The Examiner’s death also underscores the colony’s defiance of Earth’s oversight, hinting at broader institutional tensions.
Vulcan Colony Security is represented in this event by the white-suited figure, who ambushes the Examiner, knocks the Doctor unconscious, and implants the button in his hand. The figure’s actions are methodical and ruthless, reflecting the colony’s hidden violence and the security forces’ role in enforcing its secrets. Bragen and Quinn’s later arrival, along with their guards, further underscores the organization’s control over the situation and the victims’ vulnerability.
