As the dust began blowing back in people's faces, Sky just stared at the professor. Not a derpy stare, more of an 'I've got your number' stare. She had, of course, heard from her aunt what a piece of work this Knox woman was and she was currently in the process of proving her right. Not that she had doubted Aunt Roxi one bit.

As the temporary professor told her to put her robe back on or leave, Sky just sat there and quirked up a brow. Nope, not putting the robe back on, nor was she leaving. Miss Ivy Knox was just going to have to suck it up. Though she did offer up a suggestion. "Wouldn't it be easier to learn the spells if we're not all dust covered? Oh, and Scourgify is one." There, couldn't get her for not paying attention, because she'd just proved she was.
