The next night, Ben goes to a party at Amy's house. Amy introduces Ben to her new friend, who turns out to be Madison. The two pretend to have not met one another. Shortly after, Madison obsesses over Ben—she stops by his house to meet his mom and bombards Ben with e-mails and instant messages. Ben realizes her unhealthy behavior and demands her to leave him alone. Ben's lying eats at him, but, before he confesses, Madison tells Amy first. Madison dates Ben's rival teammate, Josh. Right before their biggest swim competition, Ben is disqualified for having steroids in his urine. Ben is outraged and suspects Madison had Josh set him up. Ben confronts Josh about the drug test, revealing his suspicion. Days later, Madison accidentally calls Josh by Ben's name while they are kissing in a car. Josh realizes that Madison's obsession with Ben is real and tells her off.
