S5E3 · The Tomb of the Cybermen Part 3
Klieg’s Failed Rescue and Imprisonment

The testing room is proposed by the Doctor as a containment space for Klieg and Kaftan, offering a single door for secure imprisonment. Parry initially objects to the lack of supervision, but Hopper overrides his concerns, directing Callum to escort the prisoners there. The room’s isolation and lack of oversight become a point of tension, reflecting the group’s fractured trust and the urgency of their situation. Its role as a prison underscores the group’s desperation to neutralize internal threats amid the Cybermen’s looming danger.

Before: Empty and secure, with a single door for containment, located within the Cybermen tomb complex.
After: Occupied by Klieg and Kaftan, who discover a dormant Cybergun inside, later used by Klieg to blast a metal wall target.

S5E3 · The Tomb of the Cybermen Part 3
Hopper imprisons Klieg and Kaftan

The testing room is proposed by the Doctor as a containment solution for Klieg and Kaftan, its single door and secure design making it an ideal prison. The group’s debate over whether to leave Klieg and Kaftan in the Central Chamber or imprison them in the testing room reveals their deep-seated distrust of the pair. The testing room’s functional role shifts from a space for Cyberman experiments to a makeshift jail, symbolizing the group’s desperation to regain control amid chaos. Its mention in this event underscores the group’s fractured priorities: security over morality, logic over emotion.

Before: A secure chamber in the Cybermen tomb, previously used for testing Cyberman systems and equipment, now repurposed as a prison.
After: Occupied by Klieg and Kaftan, its purpose temporarily shifted from experimentation to containment, though its long-term role remains uncertain.
