a result, Summer reluctantly seeks a more involved role in student politics, gaining a new rival in fellow student Taylor Townsend (Autumn Reeser). They have since become friends, particularly when Taylor helped her get Marissa back in by organizing a petition. Summer is initially insecure about her relationship with Seth, because she often felt that he was smarter than her and she feared that he would break up with her for someone more like him. However, when Summer gets a very high SAT score, it gives her the ambition to change, and she begins to focus on school. Also, her relationship with Seth is closer than it was during much of the previous year, and the couple's post-graduation future is one that she finds harder to ignore. They have trouble earlier in the season deciding what colleges to go to and how it would affect their future together, but eventually they agree on going to Brown University, which is more feasible after Summer gets a high SAT score. Summer cares a lot about Seth and when he starts smoking pot, she becomes worried about him and forgives him if he promises to stop. When Summer finds out that Seth is still smoking pot, she is upset, but Seth apologizes with a letter on a napkin, admitting his lies and mistakes, and tells Summer that if he messes up again, she can show it to his parents. Summer forgives Seth. Shortly before they get their college acceptance letters, Summer says that if should she get into Brown and not Seth, she will not go. When they get their letters, to Seth's dismay this happens. Seth, not wanting to be responsible for Summer turning down a major educational and life opportunity, says he does not want to go to Brown anymore. As a result, they break up, with Seth stating when confronted by Summer that he does not love her anymore. While their future as a couple seems uncertain at this point (and is complicated by the return of Seth's ex-girlfriend Anna Stern), Summer takes a Korean pop star as date for the prom. Upon seeing Seth with Anna, Summer feels hurt. When Summer falls off the stage after being announced Prom Queen for the second time in a row, Seth runs to her and tells her the truth about Brown and they reconcile. They have resigned themselves to going to school
