Gravitron repurposed as Cyberman countermeasure

The Doctor seizes on the gravitron’s accidental deflection of a Cyberman weapon to propose a high-risk tactical maneuver: using its force field to target the lunar surface and disrupt the invaders. Hobson, initially skeptical, resists the idea due to safety concerns about the device’s angular cut-out and potential damage to the moonbase. Benoit, however, immediately grasps the Doctor’s intent and enthusiastically prepares the gravitron for manual override. The Doctor directs Hobson to position the probe lower, but the mechanism resists due to its safety locks. After Hobson disables the cut-out, Benoit successfully lowers the gravitron’s field to the moon’s surface, causing the Cybermen and their saucers to float helplessly upward. The team celebrates their victory, but Hobson quickly refocuses on repairing the gravitron to restore weather control. This moment marks a turning point in the battle, shifting the balance of power from the Cybermen to the moonbase crew while exposing the Doctor’s improvisational brilliance and Hobson’s pragmatic caution.

Initially skeptical and hesitant, shifting to cautious determination as the plan unfolds, then relieved but urgently focused on the next crisis.

Hobson begins the event skeptical of the Doctor's plan, citing safety concerns about the gravitron's angular cut-out and potential damage to the moonbase. After the Doctor's insistence and Benoit's enthusiasm, he reluctantly disables the safety cut-out, allowing the probe to be lowered. As the Cybermen are lifted into space, he transitions from cautious resistance to determined action, then refocuses on repairing the gravitron to restore Earth's weather control. His leadership balances pragmatism with urgency, reflecting his duty to protect both the base and the planet.
