Mrs. Arkwright was a geography teacher in Liverpool, England, Earth, at some point in the 22nd-23rd centuries. Mrs. Arkwright taught an adolescent Dave Lister, and had an affair with him, even having a "pregnancy scare" with Lister. This was sometime after Lister had already lost his virginity, aged 12, with Michelle Fisher on Bootle Municipal Golf Course. Three million years later aboard Red Dwarf, Lister remembered to Rimmer that although she was very elegant and classy, behind closed doors Mrs. Arkwright was "dirtier than a mechanics keyboard".
