Those eyes
Vanessa hid. Of course she did - that's what she's always been trained to do. No one must know of her true thoughts, and no one must be able to pierce through the veil hiding her intentions.
For the most part, acting in front of people was what she excelled at. She behaved in a way that would incite people to make assumptions that she wanted them to have. She controlled what others thought of her, controlled what they saw, and what they felt.
In more ways than one, Vanessa was more adept in hiding while in plain view of people than she was in actually hiding, though lately she had become incredible at that as well. A large part of that was because of a certain blue-eyed boy! He was completely rude and impolite, always pointing out her flaws.
