The next day, Palmer confronts Katherine about Danny's feelings for her, which Katherine dismisses. Katherine then runs into Devlin at a bar and admits that she pretended being married to Danny to avoid embarrassment. Devlin confesses that she is divorcing Ian because he is gay and also that he did not invent the iPod but made his money after suing the Los Angeles Dodgers after getting hit by a foul ball. Katherine confides in Devlin about being in love with Danny, but then Danny shows up behind her saying that he is not marrying Palmer and that he is in love with Katherine. Meanwhile, on the plane ride back to the mainland, Palmer meets a professional tennis player (Andy Roddick — Brooklyn Decker's real-life husband) who shares her interests. Sometime later, Danny and Katherine get married.
