On board Moya, Scorpius tries to persuade Crichton to yield the wormhole knowledge to the Peacekeepers. Crichton rages that he does not want to give the knowledge to the Peacekeepers, the Scarrans, or anyone. His only concern is for Aeryn and their soon-to-be-born child, but in order to live in a safe galaxy, he may have to take desperate measures. He flies Farscape One back to see Einstein, who unlocks the knowledge Crichton needs. Moya returns to the water world so that Stark can transfer the Hierarch's knowledge to the Eidelons there. The water world becomes a battleground between the Peacekeepers and the Scarrans, and Moya is caught in the crossfire. Moya seeks the most immediate refuge within range — the bottom of the sea. Moya's internal sensors are damaged and she begins to take on water as a search is undertaken for Stark and the knowledge he has. After they find him terrified and awed by the personality he has assimilated on the Scarran ship, the crew of Moya takes a transport pod to the surface. They find the Eidelon city under siege, and only a handful of survivors. During the siege, Scorpius discovers Sikozu has been relaying their position to the Scarrans in exchange for a promise for them to free her people from servitude.

In the middle of battle, Aeryn goes into labour and gives birth to a baby boy. Meanwhile, Jothee and Noranti have been rescuing Eidelon survivors from the burnt-out city. Stark manages to transfer the Hierarch's knowledge to the Eidelon high priestess, Muoma. It is hoped that with that knowledge, the surviving Eidelons can bring peace, but as they make their way back to Moya, they are ambushed by Ahkna's forces. Aeryn manages to shoot Ahkna before she can kill Crichton, but D'Argo is mortally wounded by a Scarran spear. He stays behind to cover their retreat as the living ship retrieves the others in her docking web. Commandant Mele-On Grayza, now in charge of the Peacekeeper fleet since she poisoned her lover Maryk, the Grand Chancellor, squares off against the Scarran fleet above the water planet. With Rygel's and Scorpius's admonitions ringing in his ears, Crichton seats himself in a mental projection chair and uses his unlocked wormhole knowledge to show
