Percy, too, noticed something strange. But with his thoughts so focused on something else, he shrugged off the feeling. He looked forward and saw a woman had been walking the opposite direction he was, but she paused. She looked to be around his age, and was fairly pretty. But she made him feel nervous--all new people made him feel that way.

His shoulders twitched and he looked away from her while he walked in her direction. He hoped she wouldn't really notice him.
