[3] In the first two series, it becomes apparent that Lister lusted after Kochanski from a distance and occasionally flirted with her but never had a relationship with her, never having had the courage to ask her out.

But as the ship can only officially generate one hologram at a time, Rimmer (played by Chris Barrie) refuses to allow it, and goes so far as to hide Kochanski's personality disc.

[5] It was originally going to be Kochanski's hologram that was generated, but as the script for "Bodysnatcher" wasn't finished, they dumped the idea and immediately came up with "Me²".

[citation needed] In a possible future seen in the episode "Stasis Leak" (1988), Lister finds out that his future self from five years hence has gone back in time and married Kochanski three weeks before the accident which causes Red Dwarf to leave the Solar System; their wedding and honeymoon taking place while Kochanski is on planet leave at the Ganymede Holiday Inn.

Lister's fantasy of his perfect companion in "Camille" (1991) was initially intended to be Kochanski (played by Clare Grogan once again), but it was felt that the inexplicable and implausible re-appearance of Lister's true love (or at least enduring obsession) would tip him off too early as to the true nature of the creature that Kryten (Robert Llewellyn) rescues in the episode.

[7] A line of dialogue by Lister explicitly referencing their resemblance was ultimately cut from the broadcast episode, and later included in deleted scenes on the Series IV DVD.

Grogan returns in this episode, portraying an illusion of Kochanski created by the genetically engineered lifeforms the Psirens to tempt Lister.

Kochanski discovers the unquarantined cat Lister smuggled on board and takes her, but is unable to kill her and hides her instead.

[12] Although Annett lacks Grogan's Scottish accent, in "Duct Soup" (1997), Kochanski reveals that she was from the trendiest part of Glasgow (the Gorbals, according to Lister), and had spent her childhood in "Cyberschool" with perfect computer-generated settings and perfect computer-generated friends and a pony named "Trumper" before entering Space Cadet School.

Her initial reaction to the meagre conditions of life aboard Starbug is one of utter despair, as well as disdain for the "Dwarfers" as inferior versions of the people she knew in her dimension.

After being put on trial via a scan of their minds, the original charges against Lister, Kryten, the Cat (also played by Danny John-Jules) and Kochanski are dropped, but the four members of Starbug, along with Holly and a Rimmer reconstructed by the nanobots, are sentenced to the brig for two years after being found guilty of abusing classified information.

[18] In Red Dwarf: Back to Earth (2009), Lister believes Kochanski to be dead, but a conversation between Lister and two children (played by Charlie Kenyon and Nina Southworth) in a hallucination caused by a female version of the despair squid, which causes joy rather than despair, reveals that her death is a cover story and that in truth she dumped Lister by fleeing Red Dwarf in a Blue Midget shuttle and that Kryten hid the truth by claiming she was sucked out of an airlock.

[22] It was originally intended that the final two episodes of Series X would see the reintroduction of Kochanski, but production problems meant that the plan had to be ditched, with replacement stories found at short notice.

In the book, she seems somewhat more intelligent and witty, is learning Japanese in her spare time, and holds her own against arrogant young officers.

Lister has a brief but intense relationship with her, spending most of the time in her quarters making love and watching It's a Wonderful Life, their favourite movie.

The novel ends with Kochanski and Lister, stranded on an idyllic world in an unknown parallel universe, attempting to start a family with help from the Luck virus.

[29] In the unaired pilot for the American version of Red Dwarf, Christine Kochanski was played by Elizabeth Morehead.
