Jamie’s remark sparks solvent solution

In the moonbase sickbay, Jamie’s insistence on leaving his recovery bed—despite lingering pain—ignites a tense exchange with Polly and Ben, who prioritize his rest over tactical planning. The conversation reveals the Cybermen’s vulnerability to radiation, but the Gravitron’s power pack is dismissed as too dangerous. Jamie’s offhand remark about 'sprinkling witches' with holy water triggers Polly’s scientific intuition, leading her to hypothesize that acetone (a solvent for plastic) could dissolve the Cybermen’s chest units. Ben’s skepticism contrasts with Polly’s rapid problem-solving, exposing their fractured unity while advancing a critical tactical breakthrough. The scene underscores the companions’ divergent approaches—Jamie’s impulsive bravery, Ben’s cautious pragmatism, and Polly’s analytical ingenuity—and sets up the 'Polly cocktail' as a potential weapon against the invasion.

Cybermen's Chest Unit Plastic

The plastic in the Cybermen’s chest units is identified by Polly as a critical vulnerability. She notes that nail varnish (a plastic) can be dissolved by acetone (nail varnish remover), leading her to hypothesize that the same principle could apply to the Cybermen’s armor. This object is central to the companions’ strategic discussion, as it represents the weak point in an otherwise formidable enemy. The plastic’s composition becomes the key to unlocking a solution, transforming an abstract threat (the Cybermen) into a tangible problem with a potential chemical remedy. Its mention shifts the group’s focus from radiation to a more accessible and immediate countermeasure.
