 Written by Rob Grant and Doug Naylor, and directed by Ed Bye and Paul Jackson, the episode features the crew's attempt to escape the influence of a white hole.Dave Lister is disgusted when he finds that Kryten had repaired Talkie Toaster – an automated toaster whose AI became obsessed with toasting anything bread-related and unwilling to accept refusal of his products, leading to him being smashed up as a result.Kryten explains that he rebuilt the toaster to be a guinea-pig in an experimental procedure called intelligence compression, which would restore an AI's former IQ at the cost of a reduced operational lifespan, hoping to use the same procedure to cure Holly's computer senility.
