Doctor overrides gravitron safety protocols

The Doctor, observing the Cybermen’s retreat after their weapon is deflected by the gravitron’s force field, seizes on the device’s potential as a countermeasure. He proposes manually overriding its safety protocols to aim the gravitron’s probe at the lunar surface, directly targeting the Cybermen. Hobson, initially skeptical, reluctantly agrees after Benoit—eager to test the unorthodox plan—prepares the gravitron. The Doctor and Hobson physically struggle to lower the probe beyond its automated limits, revealing the device’s built-in safety cutouts. Once disengaged, the gravitron’s full power is unleashed, lifting the Cybermen and their saucers into space. The crew celebrates the victory, but Hobson immediately pivots to restoring the gravitron’s function, underscoring the lingering threat to Earth’s climate. This moment tests the crew’s trust in the Doctor’s reckless ingenuity while escalating the stakes—success against the Cybermen comes at the cost of further destabilizing the moonbase’s critical systems.

"DOCTOR: "We'll try bringing it down by hand.""
