Go to your history class as normal.

You walk around the frozen girls in the stairway and finish climbing the stairs to 600. You walk in Mr Doerror's class to see a wave of inanimate students. You walk over to Mr Doerror and wave your hand in front of his face.

"Nothing." you say observantly.

You walk in and out if the aisles of your class exploring the tired students expressions until you reach one in particular that catches your eye.
