I found it interesting that Doug mentions in the documentary that he'd like to use future specials to answer long standing questions in the way that this one did with what happened to the Cat race. It made me speculate on what long standing questions these specials might explore. Obvious ones would be: What happened to Rimmer after he left to become Ace. The ending of Series 8 (I hope they don't go there, honestly). What happened to Kochanski. However, for me, the biggest one that I'd like to see explored is the unresolved Stasis Leak loop. I've always thought that there is the potential here to have the present crew interact with archive footage in the way Star Trek did with Trials and Tribble-ations, so I'd like to see a future special focussing on Lister actually wondering why the 'five year' prophecy didn't come true. What would other people like to see future specials concentrate on?
