At Dimension Jump 2011, Doug Naylor hinted in an informal fan discussion that the series might have a consistent plot arc, continuing a tradition started in Series VI onward. Reports on the ground however indicated that the main episodes plots themselves were by and large unique. In the end, there is a vague sub-plot of Lister's search for Kristine Kochanski, as first established in Back to Earth and is referenced in several Series X episodes. The final two episodes of the series were intended to build on this, but were scrapped when the location shooting budget was tightened. The crew's over-riding goal of getting back to Earth is also re-iterated several times as well, and the quantum rod plays a role in two episodes. [x] So what was going to happen? Doug obviously has a specific idea where Kochanski is. I read somewhere that Kochanski was originally supposed to rejoin the cast in X, but I can't find it now.
