Timeslides - S3-E5
Character mistake: The assassination attempt on Hitler in 1944 was in Rastenburg, not Nuremberg as stated in this episode. (00:08:50)
Character mistake: When Rimmer, Cat and Kryten go down to the cargo hold to search for the Polymorph, Kryten says "It's here" and "somewhere", but he delivers the line in an English accent and not in his robot voice. (00:13:15)
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.
