'Grey's Anatomy' is considered one of the great television shows of our time. The high-intensity medical drama, now in its 23rd season, follows a team of doctors at Grey Sloan Memorial who are faced with life-or-death decisions on a daily basis. They seek comfort from one another and, at times, more than just friendship. Together, they discover that neither medicine nor relationships can be defined in black and white. Watch 'Grey's Anatomy' Thursdays 10/9c on ABC.
