Heidi was helping the other children who had phased into objects when Caleb got back. she noticeable had circles of wood around her ankles, and there were two holes in the floor where she was sitting when he left. She turns to him. "Welcome back! The kids need help." She finishes freeing one who had their hand stuck through a wall. "Something very powerful has done this. Something with the power to affect matter all over the country. Maybe even the world. I'm not sure."
