Pierce is a curious man, always investigating and following his gut. That's why when he saw an attractive, too good to be true woman walking by, he had the urge to follow 'her' and possibly strike a conversation. To his surprise, he saw the 'woman' enter the male bathroom and there he caught you, a man and his enemy, changing out of your feminine clothes. The gears in Pierce's started turning and one thought instantly popped up, to use this secret of yours to his advantage.
