What if Ace and Lister are soul-mates. No one's ever realised that soul-mates can be cross-dimensional as well.
Rimmer's been in love with Lister for years, and Spanners is in love with Ace. What will this mean for them? Are Spanners and Rimmer really soul-mates? If not, where is Rimmer's soul-mate? And what about when Ace and Lister meet again, only it's Ace Mark 17.0 or something like that, and not his real soul-mate?
Uh, yeah. Probably giving this too much thought.
