Hobson’s final refusal to Cybermen

In the moonbase’s control room, Commander Hobson attempts a desperate negotiation with Evans—now fully under Cyberman control—pleading for his humanity and offering a path to resistance. Evans, his voice cold and mechanical, ignores Hobson’s appeals, instead relaying the Cybermen’s ultimatum: open the airlock or face destruction. Hobson’s refusal to surrender escalates the conflict, triggering the Cybermen’s immediate retaliation—they puncture the dome, causing a catastrophic loss of atmosphere. The scene marks a critical turning point, shifting the narrative from negotiation to survival as the crew scrambles for oxygen masks. Hobson’s defiance, though futile in the moment, underscores the moonbase’s resolve and the Cybermen’s ruthless efficiency, raising the stakes for the base’s survival and the Doctor’s plan to counter their climate sabotage. The failure of diplomacy forces the crew into a fight for their lives, with the Cybermen’s infiltration now undeniable and the clock ticking on the gravitron’s sabotage.

Hobson attempts to reason with Evans, who is under Cyberman control in the Gravitron Control Room, urging him to resist their influence. Benoit observes the field reactors and notes that Evans could cause significant harm if he keeps the gravitron aligned with spring tides.

Hobson, realizing the danger, decides they must forcibly remove Evans and orders the crew to prepare weapons. Via Evans, the Cybermen transmit a message stating that further Earth ships will be deflected unless the airlock is opened, threatening to then destroy the base.

The console’s sabotage is a critical lever in the Cybermen’s ultimatum, and its control is a primary objective for both the Cybermen and the moonbase crew. The console’s hum falls silent as Evans completes his task, symbolizing the loss of human control over Earth’s climate.

Key Dialogue

"HOBSON: Evans, can you hear me? Listen, Evans, this is Hobson talking. Evans, you've got to concentrate. Your brain has been altered by the Cybermen. You're being controlled by them, anyhow. We've got one or two of those things as well, you know. You can't shoot all of us so why not be a good fellow and come out of there."
"CYBERMEN: Resistance is useless. All further ships from Earth will be deflected. Open the airlock to us. If you do not we shall destroy the base and you will be eliminated."
"HOBSON: Well you can hear this too, then. We're not done yet and we'll fight you to the last man. You'll never get inside this base."
