Love that comes, love that goes / And I between you

Laura and Paolo finally manage to sleep together for the first time, but Emanuele and Cristina do everything they can to complicate the situation. Cristina, gripped by a fit of intense jealousy, begins to see the ghost of her neighbor's wife. Paolo, too, must confront a ghost from his past: Laura's ex-husband, Riccardo Balestrieri, a successful writer, is returning to Rome for Christmas and will be staying at the Del Fiore house. Laura's reassurances are useless; her new man doesn't seem to like it.
