D'Argo (Anthony Simcoe) manages to destroy one of the few remaining PeaceKeeper devices on the living starship Moya -- only to cause an inexplicable reaction which blows him into space. Rescued by Aeryn (Claudia Black), D'Argo returns to Moya in a highly agitated and extremely paranoid state, convinced that fellow crew member Crichton (Ben Browder) is a murderer. Adding to this burden, Moya begins to malfunction in a terrifying fashion. "They've Got a Secret" first aired on June 25, 1999. ~ Hal Erickson, Rovi
