Sophie and Lisa are Jemima's roommates. Social climbers and the female version of a womanizer, Sophie and Lisa are the type of women Jemima dislikes, and they treat her as an insignificant person. Although the almost seem to like her, they really treat her as a maid, or live in confidant. They don't seem to even realize Jemima has feelings or emotions, and they treat her with pity and disdain. When Jemima begins to lose weight, they see her as a threat, and instead of being happy for her, they actually try to steal Ben away from her. What they don't realize, however, is that Ben dislikes women such as these, as they are shallow and undeserving of his affections. Sophie and Lisa are the stereotyped thin women of the world, which Geraldine counterbalances in the book.
