Continuity mistake: When the crew are plasticine in the screensaver, the Cat slides into the igloo. From one shot he is sliding towards the igloo from an angle, but in the next shot he is heading straight for the igloo. (00:14:55)
Continuity mistake: When The Cat does his dance with Blue Midget, he stands behind one of the legs of Blue Midget and changes his clothes. The old clothes he throws on the ground when changing disappear in the wide shot of the landing area. (00:08:55)
Continuity mistake: During the Cat's dance, he taps his feet and tilts his head back, which Blue Midget copies. In the next shot Blue Midget is looking downwards and then proceeds to do the same dance it just did in the previous shot. (00:10:00)
Continuity mistake: During the Cat's dance scene with Blue Midget, we see one shot of Blue Midget doing the air guitar move, but in the next shot, his arms are not visible at all. It changes between these two differing shots throughout the closing end of the dance routine. (00:10:10)
Continuity mistake: When the Cat does his tap dance, he starts 20 feet away from Blue Midget and does not move from his position during the dance. When he finishes, he taps Blue Midget's leg. (00:09:30)
Continuity mistake: When Kryten says about the cryptic clue, his arms are by his sides. In the next shot, they are outstretched. (00:14:15)
Continuity mistake: After the Cat has performed his dance routine, he begins to smoke a cigar and puts it down. The shot cuts to the ground controller, but when the shot cuts back to the Cat, the cigar is back in his mouth and has already been smoked. (00:10:30)
Answer: It's Queen Victoria, someone any Englishman would recognize, and needed no introduction.
Kryten was introducing the "people" to Rimmer. Rimmer isn't an Englishman; he's not even from Earth; he's from Io.
