The Lying Game

Emma wants to find out what really happened on the reservation but Ethan is avoiding her and Sutton is looking to send her packing for good. Curious about his father’s possible link to Derek’s murder, Thayer starts to doubt Alec’s alibi and begins investigating Rebecca’s past. And, Kristin grows increasingly suspicious that Ted is not telling her the entire story when it comes to Justin’s mom.

Ethan is still a wanted man in hiding with Sutton, leaving Emma to worry if justice - and love - will prevail. Discouraged by Dan's inability to crack the case, Emma takes it upon herself to find a way to vindicate Ethan. With the help of Mads and Thayer, they search for any lead that may help prove Ethan's innocence. Meanwhile, Ethan and Sutton's time alone in hiding together has lowered Ethan's guard. Sutton uses the opportunity to encourage Ethan to bond with his estranged father, looking to heal her relationship with him at the same time. And Alec questions Rebecca's motives after she agitates Ted and Kristin by offering Laurel the opportunity to produce a music demo.

Ethan insists on helping Emma get the answers she's looking for about her twin sister. So when a tattoo sparks a memory about Sutton, Ethan pursues an explanation. But the information proves costly when Ethan heads into a situation that quickly gets out of control. Meanwhile, Mads sneaks off to see Ryan, and Laurel continues to see Justin against her parents' wishes.

As Emma, Ethan and Thayer continue to search for the truth of what happened to Sutton at the lake, they follow a lead that raises more questions than it answers. But when a poorly-timed encounter threatens to expose her identity, Emma is left in a precarious position that turns her life upside down. Will she be able to recover? Meanwhile, Laurel impresses the crowd at her mom’s charity benefit with her musical talents, and Rebecca and Alec get to know each other better.

It's been a tough night for Emma and Ethan, and things are about to get tougher when they find Sutton has disappeared after their argument and the Mercer family car is missing from the garage. When the police find the car at the bottom of the lake, Emma and Ethan look to each other for support, but Thayer threatens to tear them apart with his accusations against Ethan. Meanwhile, Char's aunt, Rebecca (guest star Charisma Carpenter, "Buffy the Vampire Slayer"), has returned to town and Char is the only one happy about it.

Secrets abound in the Mercer household and Emma has had about enough of it. When she overhears an argument between Ted and Kristen, Emma thinks she finally can put a stop to all of the lies and get some real answers out of Sutton's mom. But does Emma really think that she could pry the truth out of a secret that has been hidden for almost seventeen years? Or will the secret Kristen has been hiding turn out to be not the biggest secret lurking around the Mercer house? Meanwhile, Sutton gets a glimpse into what Emma's life has been like when she is forced to pretend to be her sister while in Las Vegas.

Questions surrounding Emma arise when Thayer returns to Phoenix and everyone deals with Eduardo's accident. What does Emma know about the accident, and why does Thayer seem to know more about the situation even though he has been in L.A.? Sutton's friends are tired of the lies and demand answers from Emma. Not exactly knowing the whole story surrounding Eduardo's accident, will Emma finally tell Mads and Char about the switch to save their friendship, or will she risk it to save Sutton's secret? Meanwhile, Sutton finds more trouble than she expected at Dowinger Clinic as she finally comes face to face with her mother.

Emma is forced to go up against Neesha for Homecoming queen which causes problems with her and Sutton. Sutton and Emma both try to find more info on their mom while Alec and Ted try to hide it.

After revealing Sutton's real relationship with Ethan, the Mercers insist she invite him over for dinner. Hesitant because of his obvious feelings for Emma, Ethan obliges, only to have the dinner cut short by a disturbing visit from Dan. As Emma and Ethan struggle to keep order in Arizona, Sutton and Thayer discover shocking revelations in Los Angeles pertaining to the search for the girls' birth mother. Although the outcome may not turn out to be what Sutton had hoped for, it does lead her to wonder what everyone around her has been hiding for all these years. Will Sutton be able to find the answer about why she and Emma were separated, or will her curiosity put her and her loved ones' lives in danger? Meanwhile, Laurel falls for a new guy in school hoping she will finally have something of her own, as opposed to always being in Sutton's shadow. Unfortunately her wishful thinking is cut short when Char calls dibs on the one Laurel did not want to share.
