Mary glanced behind her in dread. She heard him following. What was with all these people who could suddenly trace her even when she was invisible?? Was her power suddenly useless? She stopped moving, convinced that she was going to die today. All the things she hadn't done, that she wouldn't-- wait. He wasn't going to hurt her?
"If, uhm, you're not going to hurt me, then, then, well, why are you being so creepy?" Mary stopped her useless retreat and watched him, still invisible. At least she could pretend he couldn't see her. If he was a teacher, he couldn't hurt her, or he'd get in trouble... right?
