When Lister says that Rimmer has hidden the ciggarettes, how is this possible, as he is a hologram.

He could have told the scutters to do it for him, but they hate Rimmer and would probably take Lister to them straight away.

Also, on the episode called Camille, where the pleasure girl turns into a female hologram, Rimmer should have realised there was something wrong instantly, as Holly cannot support two holograms at once at that point. I should point out that this is before the episode where they turn off some systems to allow for 2 holograms, which ends up in Lister having to put up with two Rimmers. Also, Holly should have detected that Camille was onboard and that she was not hologram, human or mechanoid.
