Let’s say Kochanski had been brought back as a hologram to keep Lister sane as opposed to Rimmer, how would this have played out in subsequent episodes? In what way would Kochanski have kept Lister sane (e.g. what would she have done)? What if Kochanski had left partway through Series 7, only to have been replaced by Rimmer?
Lister would have constantly been trying (and failing) to ask Kochanski out on a date, while Kochanski would have only had a vague idea of who he was, and would be constantly wondering why she had been brought back instead of someone who knew Lister better.
Then, halfway through Series IV, they would suddenly and with no explanation start bickering like ex-partners and referring to events that happened when they were a couple, leaving viewers incredibly confused.
That scene in Balance of Power would be different. She’d disguise herself as Rimmer and then look down his trousers, telling Lister she’d seen something he hadn’t. Then when Holly changes her back she still retains a crotch bulge.
Alternative universe Lister and Kochanski had a relationship and all that jazz from the new backstory injected via the soft reboot of III/IV. So did our Lister and Kochanski, really. But I gather alt. Lichanski’s relationship was more fruitful. Or something.
After watching Total Recall, Lister decides to give Kochanski an extra breast for her birthday. She is unhappy and they decide to cut it off with a holo-laser and bury it in space along with the black box and erase their memories of the entire event. Also, aliens compete their jigsaw as part of a greeting.
