Synopsis by Hal Erickson
John Crichton (Ben Browder) manages to pass through a wormhole in space, returning to what appears to be his native Australia. Curiously, he is given a chilly and hostile reception -- in fact, only John's father (Kent McCord) believes that Crichton really is Crichton. Also pulled through the wormhole are Aeryn (Claudia Black), D'Argo (Anthony Simcoe), and Rygel (Jonathan Hardy), who immediately upon their arrival are subjected to imprisonment and sadistic persecution. When Rygel is apparently killed and dissected, Crichton is forced to rethink his priorities -- and to confess his true feelings for Aeryn. "A Human Reaction" first aired on August 20, 1999.
