Nina was George Costanza’s girlfriend in “The Switch”; she was played by Charlotte Lewis. Nina is a model in which George notices she has to "freshen up" after every meal she has. This preoccupies George in which Kramer suggests she may be bulimic. George learns Babs Kramer is a matron in which he intends to attend the restaurant she works at. However, Kramer decides to talk to his mother again and convinces her to quit her job. This allows George to still be unsure. George then enters the women's lavatory himself where he hears a woman retching which turns out to be a sick woman. Nina then questions what George is doing there in which he replies wanting to know what she wanted for dessert. Nina then walks out on George.
