In my world George didnt die.. this is what happend
When George woke up that morning he knew three things for sure. Number one was that he was going to hit by a car "trying" to save someone. Number two was his life as he knew it was over. And number three was that both were going to hurt. He sighed one last time then got dressed. He forced a smile but it didn't come as easily as he had hoped it could. So he headed out the door into a new life anyways.
As he walked out he looked around. He could not tell anyone what was going on. He wished he could tell Izzie or at least Meredith. But tomorrow kept him from telling them. He knew they were going to have to watch "him" die. And that is how he had to leave it. There could be no heartwarming goodbyes or tears… not yet.
He got sit back and watch. Someone was sent in in his place to die. He hadn't really understood that part but he wanted to help over seas. And when he had signed up they asked him to report for duty the next day for a top secret deployment. So top secret that everyone had to think he was dead. He wanted to join so badly he agreed. Its was only a while ago that he realized the repercussions on his friends.
