Doctor collapses from Spectrox poisoning

The Doctor, gravely weakened by advanced Spectrox toxaemia, stumbles through the underground. Stotz and Krelper hustle him toward their escape ship but find his condition slowing their progress. The Doctor’s admission of his illness forces Stotz to abruptly pivot from contempt to urgency, all while the Doctor’s vulnerability exposes the futility of resistance. His levity about stage three of the poisoning briefly masks the severity of his state, but the exchange underscores the ruthless calculation of those transporting him—a betrayal that will later seal their alliance with Sharaz Jek to their own doom.
