“Out of Their Minds” is episode nine of season two of Farscape.
Moya has been targeted by an alien ship. Zhaan boards their ship to try and stop them from attacking, and they claim to have been attacked by Moya’s child and Crais. When the aliens attack, Aeryn’s consciousness is transferred into Rygel’s body, Crichton’s into Aeryn’s and Rygel’s into Crichton’s. D’Argo ends up in Pilot’s body, Pilot in Chiana’s and Chiana in D’Argo’s. Which means that no one is in control of the ship.
They have to convince the attackers that they aren’t a threat, with none of them in their own bodies. And there is more going on than meets the eyes.
Some amusing bits in this episode.
