The crew of the LEXX realise that the Mantrid clones are eating up all the matter in the universe, so they head for its centre in an attempt to escape to the Dark Zone, and before you can say “this is another of those stories where they mash up multiple episodes of Blake’s 7, isn’t it?” the ship has encountered a giant space web, and a sort of fungus/spider hybrid has taken control of the minds of the LEXX and Stan (though apparently its attempt to do the same to Kai broke it). The story is nicely creepy, particularly the bits where the crew gradually come to realise how serious their situation is, and the Mantrid clone plot line is an obvious but not too in-your-face climate change metaphor. I did spend most of the episode wondering what’s happened to Lyekka, though, since no one as much as mentions her and you’d think she’d get involved.
