Maya is stunned to learn that her mother has decided to sell her house and move away with her boyfriend. Toni's mother surprises her by coming to town for Joan's Mother's Day brunch. William eagerly anticipates a visit from his mother, who comes bearing a cake from his aunt's award-winning recipe.

Toni's family comes to town, and Toni worries that her mother will embarrass her in front of Todd's parents by voicing her objections to their Jewish background. Mrs. Childs becomes dejected about the bickering between Toni and her older sister, Sherri--whom Toni refuses to include in the bridal party--and falls off the wagon. Meanwhile, William worries that he will lose one of his few male friends when the man begins dating Maya.

Joan promises to support Toni as the wedding approaches, but repeatedly neglects her in order to deal with her latest drama involving Ellis, who has failed to tell her that the mother of his child has been cast as his love interest in his movie. As a result, Toni tells Joan that she is not welcome at the wedding. Meanwhile, Sivad feels threatened by Lynn's past with William and orders her to move out of William's house; and Mrs. Childs fiercely tries to keep Maya away from Toni's med student brother, Antoine.

Joan tries desperately to get Toni to forgive her and allow her to be a bridesmaid. However, it remains to be seen if there will even be a wedding, as Todd walks out on Toni because of her selfishness. Meanwhile, Lynn objects to Sivad's decision to write a poem for the wedding.

Toni continues to see her therapist, Dr. Miller. Rather than following the doctor's advice and writing a letter to her mother detailing her grievances against her, Toni instead brings her mother to her sessions. Veretta stays with Toni and Todd and monopolizes the house. Todd tries to tolerate her rude and thoughtless behavior, but insists that she stop smoking in the house. Veretta refuses, and says that she doesn't have to listen to Todd because her daughter paid for the house. They get into a heated confrontation, and wind up ordering Toni to choose between them. Meanwhile, William worries that the fact that he and Donna have such different backgrounds (she cleans bed pans for a living and insists on travelling by bus) will impede their chances of having a future together. He vows to try his best to keep the relationship going, because he considers Donna to be special. Joan obsesses over whether to resume sessions with her own therapist after Lynn and Maya make several deris

Toni is surprisingly excited about a visit from her mother, as she hopes to be pampered before having her baby. However, she soon learns that her mother actually came to town because she recently received a letter from an ""old friend""--and is considering having an affair with him. Meanwhile, William and Joan panic when J-Spot has trouble bringing in customers. They hope to correct this by giving the place an air of exclusivity.

When Maya moves into her new place, Joan ditches the housewarming for an A-list party. Toni and Todd try to come to a settlement.

A series of unfortunate events prevents Joan from being there for Toni (again) as the custody hearing takes a surprising turn.
