Ellie is Clarissa’s painfully geeky, dull (and poor) cousin, whom Clarissa reluctantly invites to the party. In the social scheme of things, Ellie is way down there. You know what that means: Clarissa doesn’t like her very much. Richard is the only one to talk to her at the party, so she basically stands there impressed by all of the important people, taking mental notes to tell her friends. This woman definitely serves as an example of the social gap portrayed in the novel and it's not tough to spot.
