Alec gives Sutton's stolen laptop back to Derek (the teenager he hired to steal it). Alec has revenge on his mind. Meanwhile, Sutton apologizes to Ethan for keeping him in the dark about switching with Emma and going to LA to search for their biological mother. Dan tells Ethan to stay away from Sutton. She's bad news and he'll end up in trouble again. But Emma confesses to her parents that Ethan is really her boyfriend, not Luke. They decide to invite Ethan over for a family dinner.
While Laurel is practicing violin by herself in the outdoor amphitheater, a new hot guy Justin jogs by and introduces himself. She's instantly smitten. At Arroyo High School, Char is all over Justin and calls "dibs" on him. Too bad for Laurel, the "dibs" code was invented by Sutton to keep the girls from stealing each other's boyfriends. Later that night at the Mercer household where Ethan is having dinner with Emma's family, his brother Dan, the cop, interrupts to say that he found Sutton's stolen laptop in Ethan's truck. Ethan says he was framed, that somebody else stole it and planted it on him.
Meanwhile, Thayer and Sutton track down Ruth Peterson (the woman whose name is on both Emma and Sutton's birth certificates) where she works at the local library. Ruth attempts to run away but they catch her. She confesses that she is not their real mother, and that she was paid by a baby broker for the use of her name because their real mother wanted her true identity kept a secret.
