Half and Half

Dee Dee and Big Dee Dee plan a "surprise" party for Charles and Big Dee Dee’s 24th wedding anniversary. While putting together a slide show, Dee Dee discovers that there are very few photographs of Mona with their father. She feels sorry for her sister and makes several attempts to cheer her up (first creating fake photos of the two, then trying to set up a lunch date for Mona and Charles), but only angers her further. Mona explains that she had accepted the fact that she and her father didn’t have the closest relationship, but Dee Dee is inadvertently opening the wounds.

Dee Dee takes a pregnancy test, although Mona feels that she might be overreacting (her period is only a day late). Before Dee Dee can check the results, her mother bursts and demands to use the bathroom. Big Dee Dee also takes a pregnancy test, which turns out to be positive. She is startled, but she and Charles quickly accept the news. Big Dee Dee gets to rub her pregnancy in the face of Phyllis, who had believed Big Dee Dee was going through menopause.

Aspiring politician Ron Brown shows up at Mona’s door in search of votes, and takes a liking to her. Phyllis quickly pushes him to ask her out, and they agree to a date. Mona then learns that Big Dee Dee recently arranged a date for Dee Dee and Ron, who have been friends since childhood. The sisters are unsure about dating the same man, but their mothers insist that it will be all right (as it is unlikely that both will be compatible with Ron).

Mona tells her friends and family that she doesn’t want to celebrate her birthday, as she would rather spend the day alone in quiet reflection. However, she soon becomes extremely bored. She is relieved when Big Dee Dee shows up, although she has actually forgotten Mona’s birthday and is just there to see Dee Dee. The two go down to the laundry room in pursuit of Big Dee Dee’s dog, and wind up trapped when an earthquake hits.

After Dee Dee loses her old room to the baby and Big Dee Dee misses several appointments, Dee Dee begins to worry that the baby is forcing her out of her parents’ life. She suffers from so much stress that she has a breakdown and hears a doll talking to her. Mona recommends that she make an appointment with Phyllis to discuss her problem.

Hoping to prove herself to her father, Dee Dee goes against his wishes and tries to personally handle a tenant who has failed to pay rent for the last few months. She must come up with a new plan of attack after the man retaliates by threatening to expose several building code violations involving Dee Dee’s apartment.

After another failed relationship, Mona decides to focus on her career for a while. She is determined to help Zora, a promising young singer, secure a contract with the record company. Zora mistakes Mona’s efforts to boost her confidence for romantic interest and develops feelings for her.

Phyllis announces that she has been seeing someone for the past month. She reluctantly agrees to bring her boyfriend, Earl, to the apartment to meet the girls. Earl is handsome, sweet and romantic, and leaves everyone (including Big Dee Dee) sufficiently impressed.

Spencer’s cousin Chauncey begins working in the mailroom at the record company and blabbing everyone’s secrets. He recalls the time in college that he walked in on Spencer and Mona apparently in the midst of a drunken tryst, creating friction between Spencer and Camille.

Dee Dee’s cousin Barbara comes to town for Big Dee Dee’s baby shower, and stays with Mona because there is no room at Dee Dee’s place. Mona is furious to learn from Barbara that Dee Dee shared things that Mona had told her in confidence about the effect her mother’s bitterness has had on her feelings about marriage.

Dee Dee invites everyone over to her parents’ house for Christmas. The Bay Area experiences a heatwave, which leads to a brownout that nearly ruins dinner. Spencer angrily declines Mona’s invitation, as the holiday brings up many issues about his absent father. Mona later offers to help Spencer track down his father.

Camille sets up Mona on a date with her best friend, the handsome and engaging Carlo, whom she hasn’t seen for many years. Mona is thrilled when she and Carlo hit it off, and believes he might be a long-term boyfriend prospect. However, Carlo is actually in love with Camille and wants to pursue a relationship with her.

Mona tries to find time alone with Nick, but her mother and Dee Dee can’t seem to get the message. Dee Dee’s longtime friend Aurora comes for a visit.

The Thornes’ plans for a well-orchestrated C-section go by the wayside when Big Dee Dee goes into labor three weeks earlier than expected. A panicked Dee Dee turns to Mona for help.

Dee Dee organizes a singles mixer at a local club. She bristles at Mona’s claim that she only dates a certain type of man (well-groomed and upwardly mobile), and tries to prove her wrong by picking up a tough guy named Keno.

Kai orders Mona to exercise some of her new power as a vice president by firing Adam.

With Drew’s christening approaching, Mona and Dee Dee vie for the right to be their brother’s godmother. They grow increasingly competitive as they buy him gifts and try to impress Charles and Big Dee Dee.

Dee Dee vies with her law school rival, Stephanie Seymour, for a summer internship.

Big Dee Dee, Phyllis, Mona and Dee Dee make plans to spend Mother’s Day together at a brunch/concert. Mona is surprised to learn that Dee Dee plans to get Phyllis a present. She scrambles to find something appropriate for Big Dee Dee.

Dee Dee runs into Clay, her ex-boyfriend with the foot fetish. He tells her that he has gotten treatment for his problem, and asks to start seeing her again. Dee Dee is not interested, but Mona and Big Dee Dee convince her that he is a good guy who deserves another chance.

Nick tells Mona that his parents are coming to town for the weekend, and that he would like her to meet them. Mona is very nervous, as she has never met the parents of any of her boyfriends.

Dee Dee assigns herself the task of personally helping Mona get over her break-up with Nick.
