Robin isn't the slimmest girl in town. In fact, shes far from it. So when Elizabeth puts her up on the board to become a member of one of the snobbiest sororities in the school, and Jessica finds out she decides to try her hardest to make it hard for Robin. Jessica sets up all kinds of terribly hard tasks that Robin needs to complete if she wants to even have a chance to get in. Elizabeth wishes that Jessica could be nicer to her, but it doesn't look like that will happen. Robin, however, does end up completing the tasks and it looks like she just might be a member after all, or will she?
