physically she will be weak, but as we know emotions are a very fickle thing. I mean, she witnessed herself murdering people, when she wakes up she will be in state of confusion of first where she is, what's going on and etc... I know cause I was on the operating table at one point too >< another thing is, she probably will freak out after waking up about the horns and the arm etc... but yes she will eventually start to gain control of herself after some time. Just not immediately after waking up>< waking up from surgery is a nightmare><
