Theodora 'Teddy' Altman
Dr. Altman took over the job as Chief of Cardiothoracic Surgery at Seattle Grace in season six. She previously served in Iraq with Owen Hunt. Although a skilled surgeon, her teaching methods might appear somewhat unorthodox. Her arrival at Seattle Grace, followed by her profession of love to Owen has caused some friction between Owen and his girlfriend, Cristina Yang. Teddy marries a patient at the hospital named Henry to get him insurance, but she eventually falls in love with him. Over time, Teddy forms a friendship with Cristina, but her friendship with Owen ends when she feels he puts the hospital before her. Owen and she eventually make up in the season finale. Owen finds out she was offered a job at the Army Medical Command, but turned it down because she wanted to be there for Owen, if he and Cristina were to separate. He ultimately fires her, and tells her that he will be okay
