Andy was still crawling on the ground of the potions lab floor when Peyton entered the classroom. He didn't even noticed that she was there. Almost like he was cut off from everything around other than finding that bracelet. Most people would notice when someone else enters the room.
He was crawling under one of the tables when he saw two feet. He lifted his head and hit the bottom of the table. "Oh crap," he said as he moved from under the table then stood up. Something he should have done before he decided to stand up to see who was in the potions lab.
