Brigadier learns of living metal's threat

Sergeant Benton briefs the Brigadier outside the bunker on the ongoing but fruitless hunt for the rogue robot. Benton reveals Professor Kettlewell’s unsettling discovery: the machine is constructed from ‘living metal’ capable of growth and sabotage. Benton speculates about a possible solution—a metal virus that might dissolve the robot’s structure—but hesitates. The Doctor seizes on the idea with urgency, realizing Kettlewell’s research could be the key to stopping the rising threat. The Brigadier receives a second jolt to his military assumptions about scale and vulnerability as the Doctor accelerates the response. The moment pivots the mission from containment to solution-seeking.

Frustrated by the threat’s evasion of conventional solutions but intrigued enough to allow a shift toward scientific investigation

The Brigadier listens impassively to Benton’s report on the prolonged and unsuccessful search, responding with dry frustration about the robot’s immunity to bullets. His military mindset is visibly disrupted by the revelation of living metal and the mention of a metal virus. He reluctantly defers to the Doctor’s urgency but insists on maintaining operational oversight by sending Harry with him.

Goals in this moment
  • To ensure UNIT maintains control of the response despite the escalating weirdness of the threat
  • To balance skepticism with openness to unorthodox solutions that might finally neutralize the robot
Active beliefs
  • Conventional military force should solve conventional threats, but this is anything but conventional
  • Scientific insights are valuable but must be harnessed under proper oversight and in controlled conditions

Internally exhilarated by a scientific breakthrough, masking it with performative urgency to overcome others’ doubt

The Doctor listens intently to Benton’s revelation about the robot’s living metal composition, then immediately seizes on the metal virus theory with growing excitement and urgency. He leans into Benton’s hesitancy, extracting the key details with focused precision before demanding action. His physical presence is commanding, his tone shifting from curiosity to decisive urgency.

Goals in this moment
  • To immediately investigate Kettlewell’s living metal and virus research as the potential solution to stopping the robot
  • To override bureaucratic hesitation and redirect the mission toward a scientific fix
Active beliefs
  • Scientific solutions are more reliable than brute force against advanced alien technology
