Allan and the female alien arrive on "Oceano", joining Laura, Paul and Anders. The alien regains consciousness and smiles at the three men, but not Laura. The alien refuses to eat all food offered and will not let Anders take a blood sample. That night, as Paul is guarding the alien, she attacks and kills him, draining his blood after first hypnotizing him. The surviving astronauts decide to keep her alive by feeding her blood from the ship's plasma supply. When this supply runs out, she kills Anders and feeds on him, leaving Laura and Allan the only humans aboard.
