Gil meets Gabrielle, an antiques dealer and fellow admirer of the Lost Generation. Gil later discovers Adriana’s diary from the 1920s in a book stall on the Seine and finds out that she was in love with him. Reading that she dreamed of receiving a gift of earrings from him and then making love to him, Gil attempts to steal a pair of earrings from Inez to give to Adriana, but is thwarted by Inez’s early return from a trip.
Gil purchases earrings for Adriana and, returning to the past, confesses his love for her. As they kiss, they are invited inside a carriage by a richly-dressed couple and are transported back to the 1890s Belle Époque, an era Adriana considers Paris’sGolden Age. They are taken to Maxim’s Paris, and eventually to the Moulin Rouge where they meet Henri de Toulouse-Lautrec, Paul Gauguin, and Edgar Degas. When Gil asks what they thought the best era was, the three determine that the greatest era was the Renaissance. The enthralled Adriana is offered a job designing ballet costumes, and proposes to Gil that they stay. Gil, however, realizes that despite the allure of nostalgia, it is better to accept the present for what it is. Adriana elects to stay in the 1890s, and they sadly part ways.
Gil retrieves his novel from Stein, who praises his progress as a writer but questions why the main character has not realized that his fiancée (based on Inez) is having an affair with a pedantic character based on Paul. Gil returns to 2010 and confronts Inez. She admits to sleeping with Paul, but dismisses it as a meaningless fling. Gil breaks up with Inez and decides to remain in Paris. Taking a walk at midnight, he meets Gabrielle and, after it starts to rain, he offers to walk her home and learns that she likes Paris in the rain too..
