Rimmer's mother, played by Kalli Greenwood, is referred to several times in the series, not altogether consistently. In "Polymorph" (S3,E3), Rimmer describes her affectionately as "prim and proper", almost austere but with no time for fools. Yet in "The Last Day" (S3,E6), he indicates that she was overly sexually promiscuous. In "Dimension Jump" she is briefly shown as a mother who is concerned for her son's upbringing and education but is insensitive to his feelings (for example, lecturing him about his situation at school while he is hanging upside down as the result of a mean prank by his brothers, rather than help him down first).
