In their efforts to create a prototype wormhole, Crichton (Ben Browder) and Aeryn (Claudia Black) inadvertently damages the Farscape 1 module. Landing on the Dambaba Depot for repairs, the two crew members run afoul of the Bloodtracker, bounty hunters hired by PeaceKeeper captain Crais to recapture Zhaan (Virginia Hey), D'Argo (Anthony Simcoe), and Rydel (Jonathan Hardy). Despite the imminent danger, Zhaan finds time to revel in the euphoria of solar flares. "Til the Blood Runs Clear" originally aired on July 9, 1999. ~ Hal Erickson, Rovi
