They go to the hospital with a clipboard, they begin to interview the Doctor for their "relationship education" class. Doctor Chris lead them on that he was gay, by calling his old girlfriend by a partner, and that she was a doctor so he called her by doctor.

As she is leaving the hospital room, she picks up her bag, and under it, she sees Doctor Chris's calendar. Under that day, she sees "Pizza with Leslie." At lunch with Holly J., Anya makes a plan that her and Holly J. are going to the same pizza place that Doctor Chris is going to at 7pm. Instead of going up to Doctor Chris and talking to him, Anya makes Holly J. pretend to choke on an olive, so that Doctor Chris can come over and help her. After he does, Anya asks if she can reward him with a thank you dessert. He declines the offer because he is with someone for dinner. The next day at school, Anya and Holly J. call doctor Chris, but Anya hangs up before he answers because she is too nervous. Almost immediately afterwards, Doctor Chris calls back. Anya answers, knowing that if she didn't, it would go to voicemail and he would know it was her. She thanks him for helping Holly J. yesterday, and to Anya's surprise, he asks her to dinner that night. She accepts and they say goodbye and hang up.
