I'd just like to clarify somehting, since Camilla's performance has been brought up twice now.
Camilla's performance was anything but impressive. In fact, it would be more accurate to say it was staggeringly mediocre. At least as far as the floating tile target-portion is concerned. Camilla didn't destroy particularly many of her targets, nor was her control and use of the magic bullet anything to write home about, it was actually not that good at all, seeing as she hadn't done or used that sort of spell and maigc in (most likely) several years.
Where the pillar test is concerne,d I suppose you could call it "impressive". But really, there're likely plenty other applicants and candidates who could do the same level of damage as she did, if not more. Do recall that CAmilla's got an issue with people whore' "try-hards" or "ambitious", and as such she wouldn't exactly put any significant effort into her own actions - even for something as (supposedly) important as the Magic Knight Exam.
Now, if anyones characters are remarking on her being impressive for pacing herself or not using needless amounts of mana to cast her spells, that's fine. If someone picks up that she doesn't seem to be going all out or even trying to put on a good show, that's also fine. But her actual practical performance has been anything but noteworthy.
... But perhaps people are just noticing her because of... Certain anatomical reasons... xD
