The crew of the LEXX find a crashed prison ship and, before you can say “790 doesn’t get much to do this series, does it?” 790 has figured out how to fuse itself with the cyborg pilot of the ship and, in a state of sexual confusion, sets out to rape Stan. Xev and Kai, however, can’t help because they are finding out the hard way that in the LEXX-verse it’s always a bad idea to try and free the prisoners.
There’s some good body horror (the prisoners are physically confined to their cells by having their hearts removed), Lyekka seems to be becoming a full crewmember of sorts (which helps the ostensible gender balance a bit), and the 790 storyline’s actually less offensive than I was expecting, particularly in comparison to the earlier storyline involving Stan and rape. Probably because in this case 1) it’s clear that it’s not 790 who’s behind it, and he’s actively trying to stop it, and 2) it’s not played for cheap homophobic titillation, but as part of the sadistic dominance culture of the prison ship. Your mileage may, however, vary.
