"Grey's Anatomy" ended Thursday night with two characters' lives in jeopardy. Viewers will have to wait until next season to see if Izzie Stevens (Katherine Heigl) and George O'Malley (T.R. Knight) are alive.
Izzie, who suffered a brain tumor this season, underwent a risky surgery that threatened to take away her memory. Prior to the surgery, she told new husband Alex Karev she wanted to put a do not resuscitate order in place if anything went wrong. Izzie came out of the surgery and suffered short-term memory problems, which eventually disappeared. As she hugged Karev to celebrate gaining memory, she lost consciousness. Despite the DNR she requested, Karev urged doctors to try to resuscitate her and they did.
George, meanwhile, was inspired early in the two-hour episode to become an Army doctor. Later, friends planned to change his mind with an intervention. In the meantime, they tended to a dramatically wounded John Doe, who was bloody and near death after literally sweeping a woman off her feet to save her from an approaching bus. As Dr. Meredith Gray prepared to operate on the mysterious hero, he drew a "007" into her palm. With that, she realized with horror that John Doe, tragically, was George.
The two-hour show ended Thursday with the doctors at Seattle Grace Hospital scrambling to save both lives. Izzie entered a flashback in which she stepped inside an elevator. The elevator doors opened and she was greeted by George in his Army uniform.
