^ That's funny because basically the same thing seems to be happening to her band mate Amber, she suddenly started sitting during their performances instead of dancing when they were promoting back in May/June, SM said it was because she injured her ankles and it was no big deal .. But then she stopped performing with the rest of the girls and went back to the US .. And now SM insists that she didn't leave the group and that she's still resting because she's weak or something .. idk the whole situation seems shady =\, and Amber is also young, she's a 92-er.
