Maryann is acting more bizarre than usual during a Valentine's Day outing with Richard and her visiting son. Meanwhile, Zoey moves in with Ira to spite her mother. Sparks fly between Zoey and Maryann's son, Justin. Maryann arranges a Valentine's Day dinner with her son and her new flame but panics and shows up on Cybill's doorstep with Justin and her beau, looking for moral support - just as Zoey is leaving to meet Ira. When Zoey and Justin see each other again - after years apart - they begin spending time together, and, although Maryann loves Zoey like a daughter, she fears that Zoey may break her son's heart. Meanwhile, Cybill spends Valentine's Day with the special guy in her life - her grandson, William. (thetvdb.com)
