Seth

Seth Cohen (played by Adam Brody) – (Seasons 1 – 4): The awkward adolescent son of Sandy and Kirsten Cohen. He is known for his quick quips and pop-culture references. He is also the love interest of Summer Roberts, on whom he had a crush since 3rd grade. He dated Anna Sternduring Season 1, but they break up due to a lack of chemistry. When Ryan moved back to Chino, Seth sailed to Portland on his sailboat and stayed with Luke and Luke's gay father in protest. Seth comes back home when Ryan returns to the Cohen household. After one of his break-ups with Summer, he had a fling with the bartender at the Bait Shop, Alex. He breaks up with her because her lesbian ex-girlfriend shows up, but eventually he realizes that he loves Summer. He lies to Summer in season 3 about getting into Brown, but only to make sure that she doesn't throw away her dream of going. The truth comes out eventually and he gets into RISD. He proposes to Summer in the fourth season, thinking that she might be pregnant. After he learns she is not pregnant, the thought of marriage begins to scare him and they engage in a game of chicken over who will be the one to terminate the engagement. In the finale, six months after a tragic earthquake, Seth and Summer take time to pursue separate interests but get married sometime in the future with Ryan as the best man and Taylor as the maid of honor.
