S5·E8 When Hearts Attack (2)

Joan believes that she has had a heart attack, although the doctor insists that the episode was only an arrythmia. Joan's mother explains that she did not sleep with William; she had gone to his house to talk, and was in a robe because she needed to shower before her flight. (William had called Joan, but Lynn erased the message because she was expecting a call about a kangaroo.) Although the misunderstanding is cleared up, Joan begins to have second thoughts about William...and then has second thoughts about her second thoughts. Meanwhile, Maya goes on Lynn's public access television show with the belief that she is going to promote her book, only to be ambushed.
