In the one-hour season premiere, we check in again with Dr. Rey and learn that business is booming--he's got more patients, more staff and more potential changes coming in the future. We also meet the two new docs, Jason Diamond and Linda Li. Dr. Diamond is a hunky bachelor who's at a crossroads with his longtime girlfriend, who's also a physician. And Dr. Li and her anesthesiologist husband have a successful practice and a strong desire to start a family. Plus, we meet two patients who both want the same thing: a fresh start.
