Celine crawled after Ashley, keeping and hearing Lucas was directly behind her. She could hear the rumblings beneath them but was too concerned about the heartbeats around her and maintaining the speed of her own. She knew they all needed to be level-headed in order to get out of here. They continued through the maze of the ceiling, twisting and turning as they followed Alex. She stopped for a brief moment as she heard the sounds of the outside growing louder- cars passing by on the nearby freeway, birds chirping and the hiss of school bus brakes. She held her hand up, palm facing the group as she continued to listen.
