Switched at Birth

Bay Kennish discovers during a biology class that she has a rare blood type which is different from her parents. Intrigued by her new discovery, Bay convinces her parents, Kathryn and John, to visit a genetic testing facility where it's confirmed that Bay is not their biological daughter. There was a mix up at the hospital and both families took home the wrong babies. Days later, the Kennishes are introduced to their biological daughter Daphne and her mother Regina Vasquez. The Kennishes are surprised to see that Daphne is deaf. John and Kathryn immediately research ways to help Daphne and suggest the possibility of Daphne attending Bay's private school, which doesn't sit well with Bay. Regina is against Daphne attending the school but agrees to move her family into the Kennish house to deal with their new family situation.

In "American Gothic," conflict looms between the polar opposite mothers when Kathryn questions Regina's parenting style. In addition, Regina, Daphne's mother, refuses to join the Kennish's in their efforts to sue the hospital that made the life-altering mistake of switching the girls at birth, leaving Kathryn to wonder, what is this stranger hiding? As the girls struggle to adjust to life together, Bay, begins seeing Ty, a boy from Daphne's old neighborhood, while Daphne goes on a date with Liam, totally unaware that he's Bay's ex-boyfriend. While Bay may have met the one guy who can keep up with her rebellious ways, Daphne, unfortunately, realizes dating a hearing person may be more difficult than she had anticipated.

In "Portrait of My Father," now that Regina and Daphne have completely moved into the Kennish's home, many of Kathryn's friends and neighbors have begun asking questions. Kathryn decides it's best to keep their situation a secret and devises a lie, in an effort to protect Bay, who quickly becomes victim to town gossip. Bay asks Daphne more about her biological father, but is shut down, leaving her more determined to further investigate. Meanwhile, John gets involved in Daphne's basketball games, and it's there that he meets Melody, Regina's best friend and Emmet's mother, who also happens to be the school counselor and fill-in coach at Daphne's school.

In "Dance Amongst Daggers," tensions continue to grow while Kathyrn hosts the annual school benefit at the Kennish residence, where her new family becomes a spectacle for all of Mission Hills to gossip about. Toby and his friend Wilke's band are excited to perform at the benefit, but they're in need of a drummer - can Daphne's deaf friend Emmett really play the drums? As the night goes on, Daphne is faced with a heartbreaking decision -- to choose between a family she barely knows and an exciting new love interest who makes her feel that being deaf is not an issue. Meanwhile, Melody and John appear to be establishing a bond during the benefit. As rumors fly about the family's real situation, Kathryn has a difficult time accepting her husband's new friend. Making matters worse, Regina accepts a dinner invitation from the ex-husband of one of Kathyrn's best friends.

In "Dogs Playing Poker," after being caught sneaking out to be with Ty, the Kennishes force Bay to invite him over for dinner. Knowing this dinner is going to be an interrogation, Bay tries to prepare on all levels, but nothing can prepare her for the secret Ty reveals. Meanwhile, Toby recruits Daphne and Emmett to help him win a game of poker, but unbeknownst to them, this is a high stakes game and Toby may be in some serious financial trouble. With pressure to help her new brother, Daphne becomes conflicted when her morals start to outweigh her loyalty.

In "The Persistence of Memory," Bay is haunted by an old photo of a pregnant Regina and asks Emmett to help her find her biological father. With Emmett's assistance, the two manage to find his car in an abandoned junkyard, but just as Bay is about to give up, she notices a guitar pick that leads her one step closer to finding her father. Meanwhile, Daphne enrolls in the advanced cooking class at Buckner Hall where she soon realizes their kitchen does not cater to deaf people. After feeling embarrassed by an accident while in class, Daphne almost gets hit by a car, causing her to think for the first time that a cochlear implant might be a good idea. Meanwhile, Toby gets himself further into trouble when he conspires with Wilke to break into the school to steal a test.

In "The Stag Hunt," Bay searches the internet and thinks she has found her birth father, Angelo, and asks Emmett -- who has been helping Bay try to find him -- and Daphne to go with her to meet him. When Daphne finds out that Bay and Emmett have been getting together to track down her birth father, she grows increasingly upset and maybe a little jealous that they kept this a secret. Even though she's angry with them, Daphne chooses to go in hopes of confronting the man who once abandoned her, but is this the right Angelo Sorrento?

Unable to figure out why he is here, Regina assures the Kennishes that leaving is Angelo's specialty, and they will not have to worry about his presence for long. Although Regina is furious with Angelo, it becomes clear the two have a more complicated history than any have realized.
