Back To Reality - S5-E6

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.

M-Corp - S12-E5

Other mistake: When Cat picks up the can of Leopard lager which is invisible to Lister, he shakes it, pops the cap and sprays Lister with foam. The foam is visible but the can remains invisible, and that makes no sense. If we are seeing the scene from Cat's point of view the can and foam should both be visible, and if it is from Lister's then neither should be.

Meltdown - S4-E6

Question: When Kryten and Rimmer were doing the roster of their ranks, Why did Kryten skip the old woman in the black dress with the white shoulder sash between Dali Lama and Mr. Noel Coward?

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.
