Basically it involves Lister losing a game of poker to some genetically engineered life forms, and relying on a decidedly stupid scientist to save the day. Admittedly, her stupidness did get a little tedious at times, but that's easy to overlook just by considering how awesome some of Cat's lines were.
We're all acutely sorry bud. Apart from me and him and him.Yes, this was the episode where he really came into his own, partly by virtue of being quantum entangled with Kryten, meaning they delivered some of their lines in perfect synch, much to both characters' surprise.
Lister is at his slobbiest, Rimmer at his most officious (having just reinvented the ship's health and safety rulebook), and Kryten is doing a fine Hitchhikers' Guide homage. All in all, classic Dwarf, and right up there with the moose.
Not really much philosophical discussion to the episode; Kryten and Cat develop a new understanding of the nature of coincidence, and there's a whole space station set up to establish whether two wrongs do in fact make a right.
But we don't need that. Entangled is a high point of Red Dwarf X; let's just hope they can keep the momentum going for the last couple of episodes...
