Shockingly, there is rain in Orange County as the show begins. This will be a theme throughout the hour. Afraid of water, Ryan and Seth discuss their girl problems over the phone. Seth decides to buy back his boat in an effort to impress Summer one last time. Meanwhile, Ryan visits Lindsay. She is afraid to take the DNA test and is even considering moving to Chicago with her mother. Ryan convinces her to take the test.
In the Nichol household, Alex is introduced to Julie. Marissa also admits that Alex is, indeed, her girlfriend. Later in the episode, Marissa moves in with Alex and they are caught together by Seth. He enjoys this discovery very much. Marissa, however, seems hesitant about her sudden life decision.
In other news, Rebecca is still around because she never took her bus. She calls and, to Kirsten's displeasure, Sandy goes to meet his first love. They end up in a hotel room because the roads are flooded. But our hero comes to his senses at least and calls Kirsten. On the way home, the car slides off the road and Rebecca finally leaves because the cops are called. When Sandy returns to Newport, Kirsten greets him with a kiss.
The entire family gathers for the DNA test and it comes back positive: Caleb is Lindsay's father! Nevertheless, Lindsay chooses to follow her mother to Chicago because she does not wanna be "Caleb Nichol's daughter." Ryan is sad. Summer is also distraught because she realizes that she loves Seth. At the airport, she tells this to an understanding Zach. Going straight to the Cohen's, she finds an upside down Seth, one who had been trying to fix the satellite. In the rain, the duo kisses and hearts melt across FOX television screens.
