In To Market, To Market, Carrie (Sarah Jessica Parker) is getting so nervous about her date with Berger (Ron Livingston) that she decides to go on a Sim-u-date to calm her nerves. Great Sexpectations sees Carrie realising that the passion she and Berger feel for each other doesn't translate to the bedroom.
In The Perfect Present, Carrie is concerned by Berger's hostile reaction to his ex-girlfriend's voicemail message. In Pick-a-Little, Talk-a-Little, Berger reacts badly to Carrie's jokey criticism of his new novel. In Lights, Camera, Relationship, Carrie and Berger's relationship starts to look even more fragile when Carrie gets a big advance for her book just as Berger's option is dropped by his publisher.
In Hop, Skip and a Week, Berger and Carrie drift even further apart and he finally dumps her - by Post-it note. In The Post-it Always Sticks Twice, Carrie vows to her friends that she won't badmouth Berger - but when she runs into some friends of his the temptation proves irresistible. In The Catch, Charlotte (Kristin Davis) gets married to Harry (Evan Handler).
A Woman's Right to Shoes finds Carrie's new Manolos being stolen at her friend's baby shower. In Boy, Interrupted, Carrie runs into an old high school boyfriend, who is in town to attend a local psychiatric facility. The Domino Effect sees Big (Chris Noth) back in town for an operation.
In a feverish delirium he opens up to Carrie - but on recovery becomes his usual cool and closed-off self. In One, Carrie meets Aleksandr Petrovsky (Mikhail Baryshnikov) at a hot new art exhibition. In Let There Be Light, Carrie stays over at Aleksandr's apartment and the two become an official item.
In Catch-38, Aleksandr tells Carrie that he has a daughter in Paris, and that he doesn't want any more children - leaving Carrie to wonder if, at 38, she's willing to give up a man for a baby she may or may not want to have. Out of the Frying Pan sees Carrie walking out on Aleksandr when, during a conversation about Samantha's (Kim Cattrell) breast cancer, he mentions a friend of his who died of the illness. In The Cold War, Carrie arranges for her friends to meet Aleksandr, but he doesn't show up, and it turns out he's anxious about his forthcoming exhibition in Paris.
In Splat, Carrie accepts Aleksandr's offer to accompany him to Paris. In An American Girl in Paris (Part Une), Carrie, left to her own devices on the streets of Paris while Aleksandr prepares for his exhibition, is missing her friends and her life back home. In the final episode, An American Girl in Paris (Part Deux), Carrie returns to New York and her friends with Big after he tracks her down in Paris and they realise they are meant to be together.
