"East Side Story" is the 23rd episode, and first season finale, of the dramedy series Ugly Betty, which aired on May 17, 2007. After ABC had previously announced 22 episodes for the season, this 23rd episode was added for the debut season, due to the series' success.

As Betty returns from Mexico, having failed in her attempt to secure a visa for Ignacio, she attempts to call Henry. At first Betty starts hesitating, but goes through with it by summoning the accountant to the copying room. She begins to tell him that she is going to fight for him after realizing that when you find something good in life, you have to go after it. Henry tells her that he and Charlie have broken up, and says that he wants to be with her, to Betty's delight. They decide to have their first date together. As Betty is preparing dinner for her and Henry, Charlie shows up at Betty's house to reveal that she is pregnant. When Henry shows up, Betty tells him to talk to Charlie and the two leave. Betty waits distressed that night and following morning as none of her messages are returned. She finally hears back from Henry, who asks her to meet him. He tells Betty that he never had a father growing up and doesn't want to be absent from his child's life. He has decided to return to Tucson with Charlie, who wants to go back to her hometown and, after sharing their last kiss, says goodbye. Hours later at her orthodontist's office, Diane, a technician asks Betty how her date went. She tells her Charlie, his ex, is pregnant and they never had a chance to be together. Diane, who has a love for romantic comedies, asks more about this other woman who probably got pregnant on purpose. Betty tells her a little about Charlie and Diane comments Dr. Farkas has been dating a cute red-head named Charlie. Betty doesn't think she is the same girl until she notices Diane's bracelet, which Charlie gave as gifts to the staff. The ladies realize that Charlie and Betty's orthodontist, Dr. Gabe Farkas, had been dating for the past two months, adding a new twist as it is now unclear whether Charlie's unborn child is Henry's, as Charlie and Henry prepare to take off for their flight back to Arizona.

Meanwhile, Wilhelmina makes great strides in her ambitious power play by manipulating Bradford into proposing to her, as Bradford gives her a wedding ring that he made himself. However, Wilhelmina's plans for a June wedding at St. Patrick's Cathedral has been road blocked by Fabia. It appears that she has booked it for her wedding, so she forces Wilhelmina into making an exchange: She'll give up the date for the services of "That Girl", who happens to be Marc. Wilhelmina agrees and Marc (or "Marco" as Fabia calls him) becomes Fabia's slave. However, the exchange is called off as Wilhelmina gets Marc back and moves up the wedding date to November.
