Kaufmann has been murdered. As he was the last person to see him alive, Devlin is arrested and confined to the observatory (as the station lacks a proper brig). He escapes by cutting off the only air vent in the room, which tricks the computer into opening the door to restore the air supply. After escaping, Devlin discovers unusual eggs on a cargo shuttle. Doctor Chu walks in and reveals herself to be a shape-shifting alien responsible for placing the eggs, with a plan to replace the Cerberus crew and spread themselves throughout the galaxy. Devlin flees, but eventually kills the creature by igniting a fuel tank in the engine room. Maintenance Officer Meyer arrives after hearing the explosion and, afraid of being fired for incompetence, asks Devlin to keep the engine damage a secret so he can fix the problem without anyone ever knowing. Roland overhears the conversation from outside the room and attempts to escape on the transport, unwittingly carrying the alien eggs with him. Devlin is forced to break into the station's armoury and destroy the ship with Cerberus' laser cannon to prevent the aliens spreading throughout the galaxy. Devlin is then confronted by an armed and furious Captain Shannon. It turns out Shannon's wife served on Devlin's ship, which was destroyed in the Company Wars, and Shannon believes Devlin left her to die. Shannon arranged Danny's transfer to Cerberus station and sabotaged the probe to kill him, so that Devlin would feel the pain of losing a loved one just as he had. As Shannon is about to kill Devlin, Meyer jumps him from behind and Shannon is shot dead in the struggle. While this is happening, Ward is in an armed stand-off with the rest of the Kobayashi crew; he witnessed an alien changing from human form and went on a berserk rampage. Brooks impatiently attempts to snatch a grenade from Ward's hand which detonates, making the corridor unstable. Devlin and LaPaz retrieve Brooks' body and seal the corridor from the outside seconds before it de-pressurizes. The engines on Cerberus need a replacement part which can only be found on the probe which killed Danny. Devlin flies out on a scout shuttle to retrieve the part but while he was out, Mogami-Hudson attempt to kill the aliens by cutting off all life-support on the station. (apart from inside their own labs) Devlin uses the shuttle
