It is set in the surgical wing of the fictional Seattle Grace - Mercy West Hospital, located in Seattle, Washington. A major theme of the season is the characters adapting to change, as all of the fifth - year surgical residents have turned into surgical attendings, and are now teaching interns, and operating on their own surgeries. The early episodes of the season depict the characters dealing with the aftermath of the season eight plane crash that claimed the life of Lexie Grey ( Chyler Leigh ) and upon rescue Mark Sloan ( Eric Dane ), who dies in the first episode. Derek Shepherd ( Patrick Dempsey ) finds his surgical career in doubt after badly damaging his hand but ultimately his sister Liz ( Neve Campbell ) donates a nerve from her leg and Callie Torres ( Sara Ramirez ) is able to save his hand. Later, Shepherd receives more good news when his wife Meredith Grey ( Ellen Pompeo ) discovers that she is pregnant, despite her previously being told that it was unlikely that she could conceive. Cristina Yang ( Sandra Oh ) is severely traumatized upon rescue and suffers from brief reactive psychosis and eventually decides to take up her fellowship in Minnesota, though soon grows unhappy in her new surroundings and returns to Seattle after the death of her friend and mentor, Doctor Thomas. Arizona Robbins ( Jessica Capshaw ) survives the plane crash in spite of her leg injury, but upon return her wound becomes infected and her leg has to be amputated to save her life. Robbins reacts badly to this, becoming bitter and blaming her wife Callie and her former friend Alex Karev ( Justin Chambers ) and refuses to leave her bed or return to work. Derek discovers that prior to the plane crash, the hospital had recently changed airlines to one with a poorer safety record for budgetary reasons, resulting in the four crash survivors ( Grey, Shepherd, Robbins and Yang ) deciding to pursue a lawsuit, and it soon becomes apparent that chief of surgery Owen Hunt ( Kevin McKidd ) had given the go - ahead to the change. To prevent the doctors ' court case from being thrown out, Hunt decides to divorce Yang, but the two secretly resume their relationship and agree to start again. Despite contemplating a settlement, the doctors decide to continue with the lawsuit and eventually are awarded fifteen million dollars each, but the insurance company discovers an unexpected loophole and refuse to pay, resulting in the hospital itself becoming liable, putting its future in extreme doubt. Dr. Alana Cahill ( Constance Zimmer ) is appointed to cut costs at the hospital and she eventually decides the best course of action would be to seek out a new buyer and attracts the interest of a company named Pegasus. Later however, Torres and Richard Webber ( James Pickens Jr. ) discover the unpleasant consequences that would fall upon the hospital should they be taken over by Pegasus prompting the four crash survivors ( and Torres on the behalf of Sloan ) to pool their money together in a bid to purchase the hospital themselves and quit their jobs, resulting in Pegasus pulling out. The doctors run into trouble when they fail to secure an extra benefactor, but at the last minute Catherine Avery ( Debbie Allen ) reveals that the Harper Avery Foundation is willing to provide a majority share in the company, on the condition that they have at least one member on the board of directors. The doctors agree and their purchase is complete, only for Catherine to appoint her son Jackson Avery ( Jesse Williams ) to part of the board, effectively putting him in charge of the entire hospital. In other storylines, Miranda Bailey ( Chandra Wilson ) marries her partner Ben Warren ( Jason George ), despite suffering from last - minute nerves and missing the original wedding ceremony due to Adele Webber ( Loretta Devine ) being admitted to the hospital. Adele later dies after her surgery, leaving her husband Richard wracked with guilt due to his relationship with Catherine Avery. A new group of interns arrives at Seattle Grace and soon Karev strikes up a close friendship with Jo Wilson ( Camilla Luddington ) but the pair fall short of developing a romance, despite other characters commenting on their chemistry. After failing her board exams in season eight, April Kepner ( Sarah Drew ) returns home to Ohio, but is later brought back by Hunt and resumes her job at the hospital. Upon her return, Kepner restarts her sexual relationship with Jackson, despite being filled with conflict due to her religious beliefs.
