As far as I’m concerned, obviously, Arizona hasn’t gotten over the trauma of what’s happened to her [and] not just because she’s blaming Callie. That’s sort of the symptom of the problem. But Arizona lost a leg, she went through a terrible plane crash, and was lost in the woods. While we watched her be angry for a while, you know Meredith and Christina have been through more PTSD than anyone in the world and we’ve watched them learn how to deal with it — I don’t think Arizona has learned how to deal with it
