Hello! First of all I'd like to shortly introduce myself. My name is Marc and I'm 19 years old. I'm from Germany, so my Englisch is not very well. Sorry about that. Maybe the resurrected Rimmer from series 8 died once more and then became a hologram again. Then he got the knowledge of the former Rimmer, the one who became Ace. I mean, it could be possible that a hologram's knowledge can be saved somehow. Of course that wouldn't explain how he can be a hard-light hologram but I think that's the tiniest problem. Maybe Kryten studied the technique after Legion gave it to them and then rebuilt it. What do you think? Does this make any sense?
