Season 3, Episode 20:

Into the Lion's Den, part 1: Lambs to the Slaughter
As Moya and Talyn hide behind a moon several arns away, the crew board Scorpius' command carrier and, in keeping with their agreement, are granted full diplomatic rights and immunities. Crais asks that an addendum be added to their agreement so that Talyn can be brought aboard for his cognitive replacement, and Scorpius agrees. The situation is troubling for all the crew, but particularly Aeryn, who finds herself among former friends and comrades that now thing she's a traitor. But despite the reluctance of Peacekeepers to harbour criminals, they give the crew what they want: D'Argo receives surgery to remove the chain links from his time in prison, and learns the location of his wife's murderer; Rygel gets intelligence reports on the Hynerian political situation, allowing him to plan a return to power. Meanwhile, Crichton goes to work for Scorpius, examining their wormhole research. Crichton gives assurances that he's really trying to work out the Peacekeeper's problems with liquefaction and the like, but Scorpius suggests that Crichton is subconsciously holding back.

Things quickly go pear-shaped. Some disgruntled Peacekeepers attempt to goad D'Argo into breaking the terms of the diplomatic agreement, and he, Chiana, Jool and Rygel decide to return to Moya. However, Moya is soon attacked and captured by a different group of Peacekeepers under the command of Commandant Grayza, who has come to relieve Scorpius of his command and finally capture the infamous crew of Moya. Grayza confirms that the Luxans have signed an agreement with the Peacekeepers as part of a strategy to secure a peace treaty with the Scarrans, something that Scorpius' wormhole research threatens. Scorpius forces Grayza to back down and leave, but she promises to return with backup from Peacekeeper High Command. Moya and the crew are freed, but Scorpius begs Crichton to help him finish the wormhole research before Grayza can take it out of their hands.

Grayza contacts some Peacekeeper officers aboard the command carrier and asks for their help in removing Scorpius from power. They hit upon the idea of killing the less-well-defended Crichton, and because of the I-Yensch bracelet, this would kill Scorpius as well. They attack Crichton and Aeryn in the bowels of the ship, but Scorpius quickly realises what's going on and dispatches Braca and a security force to help. Once safe, Crichton angrily goes after Scorpius and his claims of diplomatic immunity and freedom, but Scorpius still thinks Crichton is stalling, and he's prepared an ace in the hole: Earth. Scorpius knows its location and he's dispatched a Peacekeeper fleet, even though it will take them 60 cycles to arrive. He gives Crichton an ultimatum, a choice between helping Scorpius finish the research or witnessing the destruction of his homeworld...
