George O'Malley was a surgical Intern at Seattle Grace. On his first day, he scrubbed in on the first surgery. During the surgery (which happened to be an appendectomy), he froze. But Preston Burke finishes the surgery. George does the same surgery on Meredith Grey, succeeding. He always did the skills lab training whenever Richard Webber would tell them to. In season, 4 George had failed his intern exams. He then re-does his intern year. He delivers a baby by himself and everyone is impressed. He quickly becomes friends with his colleagues. He later becomes the Chief’s intern. Lexie Grey sees George's file and tells him he failed his test by one point. George does his test again and becomes a second-year resident. George considers to transfer to Mercy West, but he decided not to. George gets an intern from each of his friends. Owen Hunt tells George that O'Malley would make a great trauma surgeon, and after performing a surgical procedure on a soldier who went to Iraq, George joins the army. However, before he leaves Seattle, George dies saving a woman's life in a bus accident.
