Meanwhile, Diane is excited when her college-professor sister-in-law Jeanette arrives for a visit, but a routine checkup brings Diane news she hoped never to hear again. Margaret reluctantly agrees to teach an art class for preteens and learns a valuable lesson about herself. And Shelley is stunned when her sister Susannah drops off her daughter Hailey.
