It seems like she might be on her way out. They made a huge deal about the 5% survival rate. On the other hand maybe they just want us to think she won't make it so it is a miracle when she actually survives.
I saw something a while ago that said she and George were leaving Grey's. I used to like George a lot more than I do now. I am hoping they can redeem his character a little before he leaves if it is true.
