Mark Sloan

Mark Everett Sloan, M.D., F.A.C.S. is a fictional character from ABC's medical drama television series Grey's Anatomy, portrayed by Eric Dane. Created by showrunner Shonda Rhimes, the character was introduced in season two as Derek Shepherd's best friend. Mark caused the end of Derek’s marriage by sleeping with Derek's then-wife, Addison Montgomery. Mark moves to Seattle in season three to make amends with Derek and becomes Seattle Grace Hospital's new plastic surgery attending, after which he is dubbed "McSteamy" by the female interns for his good looks. Mark's focal storyline in the series involved his romantic relationship with Lexie Grey (Chyler Leigh), one of the interns who was on his service when they started dating. Both he and Lexie sustained fatal injuries during an aviation accident in the eighth-season finale, and Seattle Grace Mercy West is later renamed Grey Sloan Memorial Hospital after their passing. Storylines Mark first appears in season two. He is a highly respected plastic surgeon, sub-specialized in otolaryngology and the childhood best friend of neurosurgeon Derek Shepherd (Patrick Dempsey). In his first appearance, he flirts with Meredith Grey, and Derek punches him in the face. Derek explains that Mark had an affair with his wife, Addison (Kate Walsh) while they were living in New York, causing Derek to leave New York. Mark travels to Seattle, intent on convincing Addison to return with him to New York, but his offer is rejected and Derek declines to renew their friendship. Mark returns during season three at Addison's drunken behest, but she again rejects him once sober. Undeterred, Mark sells his successful private practice (which he previously shared with Derek) and takes over the plastics service at Seattle Grace Hospital. During Meredith's morphine rampage, Mark finds out about his nickname McSteamy, which was given to him during his first trip to Seattle when he attempted to get Addison back and re-earn Derek's friendship. It is later revealed that Mark has slept with all of Derek's sisters. Mark has a brief fling with Addison's friend, orthopedic surgeon Callie Torres (Sara Ramirez), and develops a friendship with Derek's girlfriend, intern Meredith Grey (Ellen Pompeo). It is revealed that after Derek left New York, Mark and Addison continued their relationship for two months, during which she conceived and aborted his child. Addison broke their relationship off after she caught him with another woman.
