Thoughts on Jim & Bexley

[felineranger.livejournal.com]

I've been thinking about this a bit recently and wondered something. What do other people imagine happening to the twins in the future in show/book canon? We know Bexley dies in one reality from Future Echoes but other than that it's very open-ended, and actually kinda depressing. In any reality where the twins are born on Red Dwarf after the accident, surely a time will come when Lister and Cat have died, Rimmer and Kryten have burned out, and they'll be left alone. Even more so than Lister. What would they do? Go into stasis in the hopes of getting back to Earth? Find a planet with a GELF population and make the best of it?
Even at the end of Last Human, Kochanski tells Lister that they're about to make the first of many children. But what's going to happen to those children? Are they going to encourage them to breed incestuously to restart the human race? If they have a daughter are they going to encourage her to have sex with McGruder, the only other human man left, in order to widen the gene pool a bit?

It seems like whatever happens, Lister having kids ultimately puts those kids in a pretty shite position. Any thoughts?
