“Crichton Kicks” is episode one of the fourth and final season of Farscape.
At the end of the season three finale episode, “Dog with Two Bones”, most of the crew had either left Moya, or were planning to, leaving only some of them still on, along with Pilot. Crichton had decided to follow Aeryn, after finding out she was pregnant, and asked Pilot to plot a course; unfortunately, a wormhole opened up sucking Moya into it and Crichton was outside in his module, leaving him low on fuel and with no-one nearby.
This episode starts with Crichton having been rescued by a leviathan that, unfortunately, had come to the sacred area to die, and so it isn’t in the best shape.
Some hunters arrive, wanting to cut certain choice meats from the dying leviathan, then Rygel and Chiana arrive, but they have managed to lose Moya.
