The series focuses on a group of surgical interns, residents, and the various physicians who serve as their mentors in their professional and personal lives. While furthering their professional careers by any means possible, the characters on Grey’s Anatomy have found time to hook-up/break-up, marry/divorce, have relationships and one-night stands. Throughout the seasons, these characters have mixed and matched partners, some for the better and some for the worse. The following diagrams show how relationships change with the seasons and ultimately cross paths too many times to follow.
