Entangled (Red Dwarf)

"Entangled" is the fourth episode of science fiction sitcom Red Dwarf series X, originally broadcast on the British television channel Dave on 25 October 2012. Lister loses Rimmer in a game of poker to a group of "biologically engineered garbage gobblers", and in return gets an unwanted gift: a groinal exploder programmed to detonate in 24 hours unless Lister pays his debts. Meanwhile, Kryten and Cat become quantum entangled and do everything in perfect unison.

While chasing a space weevil, Cat encounters Kryten conducting an experiment with the quantum rod from Trojan. It unexpectedly causes the two of them to become 'quantum entangled', meaning they are more prone to coincidences such as saying the same thing at exactly the same time, especially when emotionally stressed.

Meanwhile, Rimmer comes up with a complicated new accident reporting system, involving filling out a form several pages long, which frustrates Lister. Lister discovers a moon with signs of life and heads down in Starbug, hoping to find out if his former lover Kochanski passed this way. Much later he returns - minus Starbug. He explains that he played poker with some GELFs known as BEGGs (biologically engineered garbage gobblers) and lost Starbug, as well as Rimmer. Also, the BEGGs have outfitted him with an explosive device attached to his groin that will explode if he does not pay up.

An offer of an alternative deal goes nowhere and another poker game is proposed. Unfortunately, Kryten and Cat's quantum entanglement combines with a stressed Lister's insistence that he does not 'choke' in poker games and causes the BEGGs to choke to death. Hoping to use the quantum entanglement to save his life, Lister gets Cat stressed (by cutting off locks of his hair) and the Dwarfers learn some space co-ordinates that lead them to a space station that Kryten recognises as a science institution that was staffed by scientists who were always wrong. Investigating the station's stasis pods, they discover that one is still functional and contains a professor, Irene Edgington – who turns out to be a chimp because an evolution device she invented went wrong.
