"They've Got a Secret": Trying to clear the ship of all Peacekeeper devices, D'Argo inadvertently causes an extremely strange reaction within Moya, at the same time driving himself into an inexplicable delirium. As D'Argo relives the painful events that led to him becoming a prisoner of the Peacekeepers, Moya's life support systems begin to shut down. Pilot falls unconscious, cutting off all hope of communication with Moya. The DRDs transform from mechanical servants to deadly protectors, attacking the crew with chilling resolve. As they race against time to correct the problem, the crew is in for a shocking surprise .
"They've Got a Secret" is a rather misleading title, for the secret belongs to the living ship Moya, and the crew spends the entire episode trying to find out what it is. D'Argo yanks the wrong nerve in Moya's network and shoots through the ship's bowels like a kid on a water slide. He awakens in a delusion that has him reliving his tragic past and building up to a murderous rage directed squarely at Crichton yet again. --Sean Axmaker
