Joan is also very intelligent, well-read (unlike Jeanne, who was illiterate), witty and highly ethical and will speak up for what she believes in, though she is always ignored by the others as they see her as being too "outspoken". She serves as an environmentalist, a vegetarian and activist. Mated to be attractive, though she does not recognize or emphasize this and dutifully wears an orthodontic retainer. Joan has proven to appeal to the other male characters, notably JFK, who frequently harasses her. Despite this, he is secretly attracted to Joan not only because she is immune to his charms, but also he is the only one who sees more to her as a person than Abe. In the series finale, after realizing that Abe will never see her more than a friend, JFK comforts Joan and takes her to the prom with him. It's there that she realizes her feelings for JFK and sees more to him than the arrogant jock he usually displays in front of others. When Abe came over to her house to finally tell her the truth that he is in love with her, Joan has moved on and begins a relationship with JFK.
