Susan reluctantly does a favor for Jack by attending a charity function with Jack, his wife Margo, and her incredibly obnoxious brother. When Susan finally tells the creep off, Margo and her brother storm out, leaving Susan alone to deal with an inebriated Jack, who winds up spending the night on her sofa. But the next day Margo is not quite willing to believe that's all that happened.

Susan accompanies Jack to his grandfather's funeral, hoping her tacky sympathy card to the family will go unnoticed.

Susan gets involved in a new romance with a guy who has two kids---one of whom takes an immediate dislike to her. Meanwhile, Jack takes a stand with Margo.

Margo's drunk with power during her divorce proceedings with Jack, thanks to Susan's inadvertent slip about Jack's intoxicating past: she interprets the fact that Jack fell asleep on Susan's couch as evidence that he had an affair with her, thus violating their pre-nuptial agreement. Now Susan must testify in court about her true feelings for Jack. Meanwhile, Vicky becomes obsessed with the idea that someone is tampering with her lunch; and Todd begs Luis to teach him how to dance.
