Seth was a little shocked by the sudden attack, but he easily pulled the ice out of his hoodie. "Damn it, there's a hole." The bunch of fallen snowballs gets raised in the air by Seth's invisible grip, and he crammed them all into one big snowball, a little bigger than his head. He focused enough to shoot it towards the man. It flew towards him, and headed for the man's face. He watched it happening, still acting innocent.
"What? Sir..I wasn't even trying anything." His voice had it's tone of innocence, and it was always very convincing. Growing up with his sick mother, he learned to do a lot of great lying and acting.
Seth glanced around at the ice and then looked away, half smiling. Without showing anything to tell it was him controlling what was left there, a small piece of the ice broke off into small, harmless pieces, and flew towards the back of the teacher's neck. Seth kept himself by the wall, glancing away, showing no sign of knowing what just happened.
Seth shook when he felt the cool air on his face. He gritted his teeth and walked along. Then he pulled himself off the teacher with a scowl on his face. "Nice first day," he muttered under his breath. While walking, he turned to see the girl following, but didn't mind her for now, and kept going.
I thought no powers in the corridor, Seth wanted to say out loud, but he knew it would get him in more trouble. "But I was just saying-" Then the teacher grabbed his ear and pulled. "Hey, ow! I wasn't talking back, jeez." He yanked himself from the grip but continued following him. "I'll go in lunch, but com'on just let me get to my first class, sir."
