As part of his agreement in volunteering for the terraforming program, Lister is granted the use of a symbi-morph named Reketrebn to fulfil his desires with her shapeshifting and telepathic abilities. Reketrebn is defective, however, and intends to save herself for her boyfriend. Lister isn't interested in using her for romantic purposes and asks her to turn into Kryten so he can get information out of him- Reketrebn essentially manifesting as Kryten to give Lister confirmation of his own theories based on information he has subconsciously processed and deduced, such as subconsciously overhearing a conversation about symbi-morphs in a bar and subconsciously deducing that Rimmer was Kochanski's lover in this reality rather than his evil self- before having her turn into him so she can feel the pain he feels from losing Kochanski to his evil self. After this, Reketrebn agrees to help Lister, but their attempt to escape results in them arriving on the same ship that would have taken them to the terraforming project, save that they are now in the control cabin rather than the stasis chambers.
