“We’re So Screwed: Fetal Attraction” is episode nineteen of season four of Farscape.
In the previous episode, “Prayer”, Crichton and Scorpius had managed to get the location of the Scarran base, Katratzi, that Aeryn is being taken to from the alternate Stark on the alternate Moya, using ethically dubious methods.
Now, Moya is docked with a Scarran space station that is on the way to the base. The freighter carrying Aeryn is also there, but will be leaving shortly unless they can stop it. Rescuing Aeryn from the freighter will be easier than rescuing her from the base.
In order to keep the Scarran freighter there, they concoct a scam that is just a little bit too realistic. Which could hurt themselves.
The story continues in the next episode, “We’re So Screwed: Hot to Katratzi”.
