One of the beauties of the show it that literally anything could happen - and frequently does - so we're going to be extra careful not to give away any spoilers.
Having said that, here are...
5 Things that DEFINITELY will happen in Series XII
1. For the very first time, the rest of the crew discover just how it feels to be Kryten when they're arrested by the Mechanoid Intergalactic Liberation Front.
2. The Dwarfers will come across a ship where criticism is illegal, and also a space station where the crew have developed a cure for evil.
3. All the machines on Red Dwarf will go on strike forcing Rimmer and Kryten to hold a Presidential election.
4. Lister will discover that a simple update of the ship's latest software could be a matter of life or death.
5. Rimmer will decide to leave Red Dwarf in search of a parallel universe where he isn't such a massive loser.
