Factual error: When Kryten revives Lister with the defibrillator paddles, he places them on the clothing he is wearing. Defibrillator paddles need to be applied to bare skin for the electricity to get through. (00:27:35)

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.
Suggested correction: Although it has limited solubility in water, lithium carbonate solution exists, and water forms vapour at a much lower temperature.
Please do some research. If you dissolve a salt - any salt - in water, then boil off the water, the salt remains behind in crystalline form. It's called distillation. This is how seawater is rendered into freshwater. It's not rocket science.
I have been doing research using you. You've been a valuable asset in my education, and I appreciate you sharing your knowledge. It's been fun.
Lister: Get real, man. Most eunuchs have got more balls than you.
Answer: In the book, the Cat finds the concept of a name confusing, as he's convinced he's the center of the universe and the idea that someone wouldn't know who he was is baffling.
