Factual error: Kryten tells everyone that the matter paddle transmits matter in digital form from one place to another at the speed of light - he is very clear on this point. He then locates Waxworld, which is 200,000 light years away. Okay - so when they use the matter paddle to transmit themselves to Waxworld, why doesn't it take them 200,000 years to get there?
Factual error: While it is true that lithium carbonate can be used to treat depression and other psychiatric disorders, it cannot be administered in gaseous form. It is a very stable salt and only starts to form vapour at 1,310 degress Celcius. Spraying it about as a 'mood stabliser' at that temperature, as Kryten does, is going to kill everyone on the spot.
Plot hole: Near the end of the episode Rimmer, Kryten and Lister are all in a Mexican standoff, each facing two shapeshifters who are impersonating them. The trouble is, thanks to Kryten's previous intervention Lister is now a soulless, unfeeling killing machine. Earlier he shot and killed a shapeshifter who could well have been Cat - he didn't know it was a shapeshifter and by his own admission he didn't care. We have already seen how fast on the draw he is - why didn't he just open fire on the six shapeshifters, Kryten and Rimmer in order to ensure his own survival? Don't tell me he was worried about being shot himself - fear is an emotion, too.
Trivia: "Meltdown" was originally planned to be the first episode of Series IV of Red Dwarf. However, the militaristic tone of this episode - and in particular Dave Lister's strident anti-war speech near the end of the episode - meant it fell foul of the BBC censors. The original planned transmission date (Feb 14 1991) coincided with the outbreak of "Operation Desert Storm" - the Gulf War...and the BBC felt that an "anti-war" episode of Red Dwarf would be inappropriate for a country at war with Iraq.
Question: When Holly is saying about how he has changed music he says that because of the 2 new notes he's made instruments would be bigger. "Triangles will have four sides. Piano keyboards the length of zebra crossings. Course, women will have to be banned from playing the cello." I don't understand the joke about the cello part. Could someone please tell me what he means?
