“The Flax” is episode thirteen of season one of Farscape.
Aeryn is teaching Crichton how to fly one of Moya’s transport pods in an empty piece of space and Rygel is getting on Zhaan and D’Argo’s nerves.
Aeryn is less than impressed with the speed at which Crichton is learning how to fly when their pod is pulled in by an invisible something with no mass – something known as the Flax, a trap laid by pirates.
Whilst Aeryn and Crichton are stuck in the Flax, D’Argo goes on a side trip with one of the former pirates.
The time that Aeryn and Crichton spend with each other brings them closer together. Which embarrasses them later.
Another episode with differing numbers depending on the source; it’s either twelve or thirteen.
