I am highly opposed to this - at this pace, this is more or less a repitition of what occurred to Soyeon way back in March (remember performing in crutches anyone?) and even earlier than that, Eunjung's leg injury where she still performed LD and other activities as well as Jiyeon still performing RP despite her knee incident.
I may as well actually say CCM forced her out of hospital otherwise she'd face some serious punishment for being 'lazy'. We all know what KKS's silly definition of 'lazy' is. If anyone takes into account what Soyeon said in her recent interview, it is very well possible CCM took this as a jab towards themselves, much like what Soyeon did during the LD promotion when she admitted in TV that T-ara hadn't a single vacation since debut.
At such a condition, there's just absolutely no way anyone would want to go back out to the field, regardless of determination. Hell, not even a soldier would be crazy enough to be like this.
