In season three, Cassie and Sam are officially a couple and will navigate the sometimes-choppy waters that come with their new relationship status, including dealing with the reactions of their kids, Grace and Nick. Grace moves further into the high school years and still pushes herself to excel in school while outside the classroom, learns more about her special, intuitive abilities and also feels the first blush of teen romance. Sam works to strike a balance between his duties at the hospital and private practice as well as his responsibilities as a father to Nick and, now, a romantic partner to Cassie. As always, Martha, the indefatigable Mayor of Middleton, is working hard to put her beloved hometown on the map and bring it the attention she feels it deserves.
