And on top of that, I have to learn the Full Rimmer For Extra Special Occasions.
For those outside the fandom, I'll put it simply--the H on the forehead means that person is dead (and "resurrected" as a hologram). Any explanation beyond that isn't worth attempting.
Red Dwarf, this particular hologram concept, and Arnold Rimmer (and his salutes) are copyright (Rob) Grant (Doug) Naylor.
Chris Barrie, I would assume, is copyrighted to/by himself.
