Question: does george pass his test the second time

Answer: Yes, O'Malley moves in with new intern Lexie Grey (Chyler Leigh), Meredith's half-sister. Lexie and O'Malley discover that he only failed his exam by a single point, leading him to confront Richard Webber (James Pickens, Jr.), the chief of surgery, to ask for a chance to retake the exam. He passes the second attempt, and begins to distance himself from Lexie, who has fallen in love with him. O'Malley supports Stevens when she discovers she has melanoma, and walks her down the aisle as she marries Karev. O'Malley begins to display a talent for trauma surgery, and is told by the chief of trauma surgery Owen Hunt (Kevin McKidd) that it is definitely his specialty. He then abruptly and inexplicably decides to join the U.S. Army. While his friends at the hospital prepare an intervention to convince O'Malley to stay, they all work on a severely disfigured John Doe, brought in after a horrible bus accident, in which he pushed a woman out of the way and saved her life. O'Malley writes on Meredith's hand ``007'' and she realizes it is her friend George. She runs to tell the other surgeons and they rush him to surgery. However, he flatlines and is ultimately declared braindead. There is confusion on if John Doe is really George and Callie confirms by a freckle on his hand. His organs are donated after Stevens confirms that is what O'Malley would have wanted, and he is buried a week later.
