Joan and Shirley drive home to Joan's house, where they meet Gregg (Raymond Laine), a student teacher at Nikki's college (with whom Nikki has a very casual sexual relationship). The four drink and talk. Gregg shows an interest in Joan, who rebuffs him. Joan throws Gregg out of her house after he cruelly tricks Shirley into believing that she has smoked pot. After taking Shirley home, Joan returns home to hear Nikki and Gregg having sex. Turned on, she quietly goes to her bedroom and begins touching herself until Nikki walks in on her.
