Mutants collapse as gas invades cave

The Doctor and Ky locate the injured Jo in the cave but quickly realize their fragile safety has vanished when the air turns thin and green from the Overlords’ gas deployment. Mutants stumble into the cave passage ahead, their convulsing bodies revealing the poison’s selective lethality, confirming the Doctor’s growing suspicion that the toxins target specific physiology. Stubbs focuses on his own survival while Cotton delivers the desperate final warning that the gas assault begins now, forcing the group to confront immediate annihilation and the combined cruelty of Solos’ natural and artificial poisons. Varan’s earlier observation about the cave’s warmth now seems ironic as the refuge becomes a death trap. "key_dialogue": [ "COTTON: Better off on Skybase than in here. You'll have to hurry, old son. The attack's due to start any minute now.
