Two cycles later, one of the twinned Crichtons returned to Dam-Ba-Da aboard Talyn. An Ancient in the guise of Jack Crichton had accused him of selling the wormhole knowledge given to him by the ancients. However, Crichton had given the knowledge to Furlow before ever meeting the Ancients. Furlow used the wormhole information given to her by John, as well as a replica of the Farscape One module, to conduct her own wormhole research. Her plan was to sell it to the highest bidder—in this case the Scarrans, via the Charrids. When John and Ancient Jack arrived on Dam-Ba-Da, the Charrids had already taken over Furlow's garage in order to secure the knowledge for the Scarrans, who were on their way to the planet. Before John, Aeryn, and Jack were able to destroy the information, the Scarrans downloaded some of it, so "Jack" came up with a plan to destroy the Scarran ship, deciding to build a device that used wormholes as a weapon. Before the Scarrans arrived, however, Furlow betrayed them, killing Jack. She stole the completed device—a displacement engine—and fled her shop in a vehicle, hoping to sell the engine to the Scarrans when they arrived. Crichton pursued and caused Furlow to crash, inadvertently exposing the radioactive material that powered the engine. Knowing that approaching the engine would mean risking a fatal dose of radiation, Furlow fled, and urged Crichton to do the same. But Crichton instead retrieved the engine, sacrificing his life in order to ensure that the Scarrans would not retain the information they'd just stolen.
