Upon further thought, back when Roxy looked at the folder prepared for her, she thought the act HIC wanted her to do was impossible, indicating HIC knows more about her void powers at this point. Forgetting about an ability like that would be pretty ridiculously convenient.
I was wondering that too. I'm pretty baffled that anyone is able to grab Roxy and drag her somewhere against her will. Oh well, since Hussie drew A GOOFY EXPRESSION on Roxy's face it Clearly Means that we would be fools to try to analyze this moment too closely.
