Farscape S04E21 - We're So Screwed Part III: La Bomba

The plan to rescue Scorpius from Katratzi fails and all because of the hybrid himself. He claims it was for the crew's own good, but, regardless, they are now stuck. Most still want to find another way out, but Scorpius reveals some secrets and pushes a plan to strike a major blow against the Scarrans. His target, surprisingly, is the Crystherium Utilia. The crew had better hurry, especially once the Scarrans deactivate Crichton's bomb. Success ends up depending on a secret held by Sikozu. Elsewhere on Katratzi, Rygel and Noranti search for Stark, only to run afoul of his bioloid. Meanwhile, Grayza fears her plans for peace have failed and now threatens to ignite a war.
