Ms. Tomboy is a CIA Agent
Valarie, a junior in high school. She lost her parents at a young age and was taken care off by her grandmother, who is the head of CIA division since Hillary's mom was still a young girl. Because she lost her mom and dad in a dangerous situation, she was taught how to fight since she was six years old. She was good. She then persuaded her grandmother to let her out into the world and do 'jobs'. Mostly because she wanted revenge for her parents but partly because she always wanted to do it. And she's good and cool at it.
But, not in school. NOPE! NO way! In school she's just the weird, loner, tomboy.
