Nicola Peltz confirmed she would return to Bates Motel in season 3 along with Kenny Johnson who portrayed Norma's brother Caleb. These facts were confirmed at Comic-Con 2014. Mad Men‘s Kevin Rahm joined the Season 3 cast in a recurring role, along with Sons of Anarchy‘s Ryan Hurst, and Revolution‘s Tracy Spiridakos.

After a blissful summer of closeness with his mother, living within the safe confines of home and the Bates Motel, Norman’s fears about what really happened with Blaire Watson resurface and Norma questions what really happened. Forced to look at the truths about Norman for the first time, their deeply intricate relationship continues to evolve. Norma finds herself turning to the other man in her life, Norman’s half-brother, Dylan and begins to rely on him in ways that she never expected. This relationship inevitably triggers jealousy in Norman and a new kind of love triangle between Norma and her two sons erupts.
Estranged brother and uncle Caleb returns to haunt the family throughout the season challenging the family bond even further. Pressures of the outside world take a hold of the family when newcomers Kevin Rahm, Tracy Spiradakos and Ryan Hurst arrive at White Pine Bay. After a summer of living at the Bates Motel, Sheriff Romero and Norma have grown closer but there will always have that troubling question mark surrounding Norman. Something doesn’t feel right, but spite of his instincts, Romero finds himself continually drawn back to the Bates family – and to Norma.
Emma, also determined to find out what is happening to Norman, becomes more emboldened and fearless, going after the things she wants. Familiar face Bradley returns to surprise the family and digs up old memories.
