Wait a minute. ____ is going to Minnesota; ____ is going home to Moline; ____ is going to New Orleans; _____ is going to Boston with ____; and _____ is going to Baltimore. By my count, that's seven leaving and one dead, plus the military defection.
I was very disappointed in the season finale. It left us hanging in the middle of yet another crazy life or death crisis. I'm not sure I care who survives. Yeah, I think Arizona is going to go because Callie has been bragging about how great her life is now, how in love she is, etc.
So, maybe they all get bound together by this unthinkable tragedy and decide to stay for one more year, just to keep the show going for yet another season. I wish they'd all go their separate ways, and end the show. But we have to wait at least another season for that to happen.
