Which makes the concept of him returning, and coming back all the more grand . Just like how Izzie was "beneath an intern" when she got she had to just observe and just threw a lot of hoops to get into that O.R. to perform surgery. It was hard struggle, but she did it. When she was off probation it was a grand moment. I'm imagining that for George. IMO It shows great strength and courage to come back from something like that . It's a hard thing to do, and I can totally understand the whiney and such that goes with it. Yet at the end it's all worth it, and in both cases Bailey got her babies' back .
