Carrington, obsessed with the alien, shows Nicholson and the other scientists his experiment: using seeds taken from the severed arm, he has been growing small alien plants by feeding them from the blood plasma supply at the base. Hendry finds the plasma missing when it is needed to treat Stern, which leads him to Carrington. Fogarty transmits orders to keep the creature alive, but it escapes from the greenhouse and attacks the airmen in their quarters. They douse it with buckets of kerosene and set it afire, forcing it to retreat into the storm. After regrouping, they realize that their building's temperature is falling rapidly; the furnaces have stopped working, sabotaged by the alien. They retreat to the station's generator room to keep warm, and rig an electrical "fly trap". The alien continues to stalk them, but at the last moment, Carrington attempts to communicate, pleading with the creature. It knocks him aside, walks into the trap, and is electrocuted and reduced to a pile of ash.
