Along the way to Demeter, they pick up the long lost astronaut Capt. Jacob "Jake" Brown, while stopping at an abandoned station to make some repairs. Brown initially paralyzes Huxley with a weapon, but it is revealed that he did so to prevent Huxley from walking straight into an "anti-matter zone". Capt. Brown is accepted on board as an advisor to Jonathan and, finding out that the crew is only armed with hand weapons, volunteers to build a rail-gun with the help of Beinstock in an airlock. Jonathan then receives evidence of the death of Capt. Forbes and Lani's coma that points to Leland, the psychiatrist. When Jonathan confronts him, Priscilla calls Jonathan about suspicious activity in the rail-gun's airlock. Jonathan investigates and finds Brody, the fitness instructor, is sabotaging the rail-gun, a fight ensues and the fitness instructor is jettisoned out of the airlock. A transmitter is later discovered amongst his possessions, that he was apparently using to keep in contact with a blip that intermittently appeared on the "Voyager"'s long range scans.
