Mr. McKenzie confronts her on her way out of class.

"Sana," Mr. McKenzie said as she was almost to the door, "wait here for a minute so we can talk."

Since Beatrice's order was to go to the bathroom 'before class' and there was a full five minutes between classes, it didn't prevent Sana from turning and listening to her teacher.

"I don't know how to say this but are these yours?" he bent down, reached into the trash can and pulls out her panties. The sight of her teacher holding her underwear made her immediately start to glow again.

There was no way she could lie to him, her power would give her away. Nor was their anyway she could say the words "yes those are my panties" without floating helplessly off the ground.

So all she could do was bit her lip and nod.

"That's what I thought," he said.
