Farscape Season 1, Vol. 5 - DNA Mad Scientist/They've Got a Secret
While theFarscapecrew barely maintains civility in the best of  times, nothing in the series prepares the viewer for the devious and ruthless  response they show when the DNA mad scientist offers them a way home in exchange  for a sample of their DNA... and one of Pilot's arms. They warm up by hacking  off Pilot's appendage in a savage amputation and then turn on each other when it  becomes apparent that Moya can only get to one of their worlds."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
