S5E4 · The Tomb of the Cybermen Part 4

Klieg’s Betrayal and the Doctor’s Descent

In the aftermath of Kaftan’s execution by the Cyber-Controller, the Doctor appeals to Toberman’s lingering humanity, urging him to break free from Cyber-control. Inspired by Kaftan’s sacrifice and the Doctor’s words, Toberman violently turns on the Controller, destroying it and halting the Cybermen’s advance. Meanwhile, Klieg—who has been feigning unconsciousness—seizes the Cybergun and descends into the tombs, betraying the group to seize control of the Cybermen for himself. The Doctor, recognizing the urgency of the situation, prepares to follow Toberman into the tombs to ensure the Cybermen’s destruction, leaving Jamie and Victoria behind. This moment fractures trust within the group, escalates the conflict between the Doctor and Klieg, and forces the companions into a precarious, divided position as the Cybermen’s threat looms larger than ever. The event underscores the narrative’s central tension: the external menace of the Cybermen versus the internal corruption of humanity’s ambition and greed.

Objects Involved

Significant items in this scene

Central Chamber Cybermen Security Control Panel

The Central Chamber Control Panel is a critical object in this event, serving as both a tool for the Doctor’s trap and the site of the Controller’s destruction. The Doctor crouches to rewire its circuits, rigging them to electrify the main doors as a lethal trap. Later, Toberman grabs the Cyber-Controller and hurls it into the panel, shattering its components in a burst of sparks that destroys both the Controller and the panel. This act halts the Cybermen’s command structure, temporarily stopping their advance and shifting the balance of power in the group’s favor.

Before: Functional and intact, used by the Doctor to rig an electrified trap for the Cybermen. The panel’s circuits are exposed, ready to be triggered.
After: Destroyed in a shower of sparks as Toberman hurls the Cyber-Controller into it. The panel’s destruction halts the Cybermen’s command structure, but it also removes a potential tool for the group’s defense.
Central Chamber Ladder

The Central Chamber Ladder serves as a critical access point during the event, symbolizing both the ascent of the Cybermen’s threat and the group’s desperate attempts to contain it. The Cyber-Controller climbs it to assert dominance, while Toberman’s violent rebellion against the Controller plays out near its base. The ladder’s rungs become a battleground for control, with the Doctor and Toberman ultimately using it to descend into the tombs and confront the Cybermen directly.

Before: Intact and accessible, providing a vertical pathway between the Central Chamber and the lower tombs. The Cyber-Controller uses it to climb and assert authority over the humans below.
After: Still intact but now a symbol of the group’s fractured trust and the urgency of their mission. The Doctor and Toberman use it to descend into the tombs, while Klieg exploits the distraction to slip away unnoticed.
Kaftan’s Handgun (Central Chamber, Parts 2–4)

Kaftan’s handgun is used in a futile but defiant act of resistance against the Cyber-Controller. Kaftan fires it at the Controller, but it is ineffective, leading to her execution. The gun is later passed to Hopper, Callum, and Victoria, who use it to target Cybermen, but it is ultimately abandoned on the hatch steps. Its role in the event is symbolic, representing the group’s desperate but ultimately futile attempts to fight back against the Cybermen’s superior technology.

Before: Retrieved from Kaftan’s bag and fired at the Cyber-Controller, but it fails to harm the Controller, leading to Kaftan’s execution.
After: Abandoned on the hatch steps after being used by the group to target Cybermen. Its ineffectiveness underscores the group’s vulnerability.
Klieg's Cybergun

Klieg’s Cybergun is a pivotal object in this event, serving as both a weapon and a symbol of betrayal. Initially placed on the table by Klieg, it is picked up by the Cyber-Controller before being dropped during Toberman’s rebellion. Jamie retrieves it and uses it to shoot a Cyberman, but Klieg later seizes it while feigning unconsciousness, descending into the tombs to betray the group. The gun’s theft underscores Klieg’s ruthless ambition and the group’s vulnerability.

Cybermen

The Cybermen, commanded by the Cyber-Controller, are the primary antagonist force in this event. Their ruthless logic drives the conflict, as they execute Kaftan for resisting their control and command Toberman to open the tombs. The Controller’s destruction by Toberman halts their advance temporarily, but their threat looms larger than ever as Klieg descends into the tombs to seize control of them. The Cybermen’s organizational structure is hierarchical and mechanical, with the Controller as their central figure and the individual Cybermen as drones carrying out its commands.
