In season four, J.D. finishes his residency and becomes a full-blown colleague of Cox, although their dynamic does not change much. As the season opens, Turk arrives from his honeymoon with Carla, but they soon start having issues when Carla tries to change many things about her new husband. Their marriage and Turk's friendship with J.D. experience friction when J.D. and Carla share a drunken kiss. Dr. Cox and Jordan learn that their divorce was not final, but this is not necessarily all good news. Elliot is still angry with J.D. for breaking her heart, and the situation becomes more uncomfortable still when she dates J.D.'s brother. J.D. has a new love interest of his own when a new and very attractive psychiatrist, Dr. Molly Clock (Heather Graham), arrives at Sacred Heart. Molly also serves as Elliot's mentor during her time at the hospital.
