in human beings. Armed with the injector gun, they locate the creature in a main corridor via Alpha's CCTV network. Verdeschi sounds the red-alert klaxon, confusing the invader, then broadcasts over the TV monitors on the communications post nearest to it. When the creature is goaded into demolishing it, he switches to the communications post at the next intersection and then the next, successfully drawing the creature away from Life-Support. Maya recommends leading it to an experimental chamber in Hydroponics, which can be filled with chlorine gas to suffocate it. While they lay their trap, Carter contacts Fraser. He orders the astronaut to construct a high-voltage cable barrier across the approach to the Life-Support Section, but Fraser does not have the experience. Carter recalls Sandra Benes' expertise in electronics, and she gives Fraser step-by-step instructions. Maya, in the form of a chlorine-breathing animal from the planet Kreno, decoys the creature into the chlorine-filled laboratory. Watching from the corridor through an observation window, Verdeschi sees the creature is affected by neither the toxic atmosphere nor the anaesthetic dose. Fighting for her life, the Maya/Kreno-Animal is trapped when she smashes into the commlock panel, jamming the door. Verdeschi shatters the glass partition and she jumps to safety. After leaving the Hydroponics Section, Verdeschi suggests Maya assume the form of the creature. The metamorph informs him she already tried—though able to transform into any life-form, she is unable to copy its molecular structure. The alien voice intrudes, telling them resistance is futile...simply give up the life-support system and die in peace. As Fraser completes his barricade of heavy-gauge electrical cable and connects it to a mobile generator, Verdeschi and Maya track the unstoppable creature from a safe distance. Maya breaks down emotionally, admitting defeat. Verdeschi refuses to concede. Standing outside the Weapons Section, he has an inspiration; if they cannot defeat the creature, then they should assault the beings controlling it. Deploying one of Alpha's main batteries, they fire off several volleys of laser fire into the cloud. The swirling gasses dissipate, revealing an indistinct shape. They lock onto the new target and fire, the laser blast splitting the body cleanly down the middle. Their success is short-lived as the object reforms. They fire multiple bursts—first halving, then quartering the mass. As the alien laughs maniacally, the object reassembles then withdraws deeper into the cloud. They leave to join Fraser to make their
