Doctor sabotages pyramid machine while trapped

The Doctor, forcibly inserted into the Great Intelligence’s pyramid machine by Arnold, appears to comply with the Intelligence’s demands to absorb his mind. While the Intelligence (speaking through Arnold) taunts him and threatens Jamie’s life, the Doctor subtly reassures his companions, insisting everything is under control. As Arnold prepares the machine, the Doctor secretly sabotages the wiring in the helmet, setting up a counterattack to drain the Intelligence’s power instead. The tension escalates when Jamie, misinterpreting the Doctor’s plan, orders a tame Yeti to attack the others, triggering chaos. The Colonel and Evans prematurely rescue the Doctor, disrupting his sabotage—Jamie throws the compromised headset into the machine, causing all Yeti to collapse. The Doctor’s frustration erupts as he realizes his plan to drain the Intelligence has failed, leaving the entity still active in space. The scene ends with the Doctor’s bitter acknowledgment of defeat and his abrupt departure with Jamie and Victoria.

Great Intelligence Control Helmet (Mind-Transfer Circlet)

The Great Intelligence's Mind Absorption Helmet is forced onto the Doctor's head by Arnold inside the Piccadilly Ticket Hall, linking him to the pyramid machine for mind absorption. The Doctor subtly sabotages the helmet's wiring while seated, reassuring his companions amid taunts. Jamie's premature rescue hurls the compromised helmet into the machine, triggering a surge that collapses the Yeti but leaves the Intelligence intact. The helmet's role as a conduit for the Intelligence's power—and its reversal by the Doctor—is pivotal to the event's outcome.

After: Sabotaged and thrown into the pyramid machine, causing a surge that disrupts the Intelligence's control. The helmet is destroyed in the process, its wires crossed and its function reversed.
Piccadilly Control Pyramid (Great Intelligence’s Central Hub)

The Piccadilly Control Pyramid serves as the central hub directing the Great Intelligence's Yeti army. Jamie hurls the compromised helmet into it, triggering a surge that instantly collapses every Yeti across London and severs the Intelligence's Earth link. Though the Intelligence survives in space, the pyramid's destruction marks a temporary victory for the Doctor and his allies. Its role as the nexus of the Intelligence's power—and the target of the Doctor's sabotage—is critical to the event's resolution.
