The relationship between Laurel Mercer and Emma Becker. Since Emma took Sutton's place she has grown closer to Laurel when Sutton pushed her away.
On the day that Emma and Sutton switch places, Emma goes to Sutton's house and meets Kristin, Sutton's adoptive mother. When Kristin almost drops a potted plant that she's carrying, Emma helps her with it and Laurel, who's sitting nearby, looks as though she thinks that is odd. Laurel comments that she's not wearing their grandmother's necklace and that Luke took it off to give her a hickey. She also tells her that Mads can't wait to see them in their new bikinis. Laurel sarcastically asks if she can have a ride to Mads' house and Emma says okay, which surprises Laurel. When Ted, Sutton's adoptive father, comes in and asks if anyone can take his shirts to the dry cleaners, Emma says yes and Laurel vocally expresses her surprise. When they leave the house, Emma throws Laurel the keys and tells her to drive to the dry cleaners and Mads' house. Laurel comments that she was told by Sutton to never even sit in her car but Laurel ecstatically agrees to drive. At Mads' house, Emma and Laurel hang out with Mads, Char, and Luke. Later, back at home, Emma and Laurel hang out together in Sutton's room. While Laurel paints her nails, Emma and Laurel talk about Sutton's adoption before Laurel leaves the room. The next morning, Laurel wakes Emma up and comments that everyone's going to want to see what Sutton Mercer's wearing to school. At breakfast, while Emma is eating the pancakes that Kristin has made for her, Laurel comments that pancakes we're not on Sutton's diet. At school, while walking in the parking lot, Emma and Laurel talk about what would have happened if Sutton hadn't been adopted by the Mercers, i.e. orphanages and foster care. They both notice Ethan Whitehorse being dropped off by his cop brother. Laurel wishes her good luck in her tennis match against Nisha. After the match, when Emma meets Laurel, Laurel reminds her that Emma forgot her gym bag. Later that night, at home, Emma comments that it will all be over at 10 pm. When Laurel asks what she's talking about, Emma is about to tell her when they're interrupted by Mads and Char entering the room. Sutton's two best friends convince Emma to attend Nisha's party and all four of them go together.
Laurel Mercer: "Why would you change in the middle of the night? Okay, Sutton, this isn't funny anymore. It's like you're intentionally trying to make me think there's two of you."
Emma: "There are two of us. Laurel, I'm Emma, Sutton's twin sister, and...I'm gonna need your help."
