Carrie is feeling pressured by Aidan - and society at large - to plan her wedding. She admits to Miranda that she isn't exactly feeling like a blushing bride. Miranda confesses that she isn't exactly glowing over her pregnancy. She tells Carrie that she "faked" her sonogram - feigning joy when she found out she was having a boy. Miranda convinces Carrie to go try on some bad wedding dresses. In her gown, Carrie starts to panic and has Miranda rip the dress off of her. At the coffee shop, Carrie asks the girls why she has to get married when things are great as they are. She wonders: Do we really want these things or are we just programmed?

Carrie tries to get in a marital mood with a stack of bridal magazines but she freaks out as Aidan smashes through the wall between the apartments. She tells him that she doesn't think she's ready to get married yet. Charlotte, on the other hand, attempts to get over her divorce with some tap lessons, but ends up "tapping" into her pain.

Meanwhile, Samantha learns that Richard has been seen about town with another woman. At Richard's charity fundraiser, J.J., a gossip columnist, shows Samantha yet another of Richard's conquests. Samantha is shocked at how upset she is. Enraged, she confronts Richard and tells him to stop sleeping around. He says he's just not the monogamous type. Samantha walks away and grabs J.J. for some sexual revenge but he goes soft on her. When Richard sees J.J. follow Samantha out of the bathroom he says, "Let's just keep things the way they are."

After the fundraiser, Aidan tells Carrie that he wants them to get married that night. He doesn't understand what they're waiting for. Carrie realizes that he still doesn't completely trust her. She insists that she is his but Aidan protests: "If you don't want to marry me right now, you'll never want to." Carrie doesn't know how to respond. Devastated, Aidan says, "I can't believe I'm back here again." Back home, they spend their one and only night together on the other side of the wall.

On the other side of town, Miranda has her first true maternal moment when she feels her baby kick.
