Doctor detects booby-trapped hatch forces retreat

The Doctor’s casual inspection of a seemingly secure hatch abruptly turns dangerous when he burns his hand on its edge.

This moment forces the group to abandon their forward progress, sacrificing potential gains in the mission to ensure survival. The Doctor’s dry humor fails to mask the gravity of their precarious position as the Cybermen’s relentless pursuit and the bomb’s proximity escalate the stakes. key_dialogue: [ DOCTOR: Ow!
