Addison returns to Seattle Grace to perform a groundbreaking surgery and is struck by the changes among her old friends.

Creator and Executive Producer of Grey's Anatomy Shonda Rhimes grew up in Chicago in the south suburban University Park. It was there that her interest in medicine sprung, working as a ‘candy striper', which is an American term for a hospital volunteer, while she was in high school. Shonda claims to have had a fascination with blood, guts and gore for as long as she can remember. "My sisters and I would call each other on the phone and say, are you watching the surgery on TV? We loved to watch these surgeries. I have no idea why," she said in an interview with the Travis Smiley show, an entertainment talk show in America.
