Dr. Morgan's true intent

As Ellie took her seat, Dr. Morgan smiled.

"Lucy ducks," he said.

The entire class, all 35 students, fell into a trance.

"All male students," Dr. Morgan instructed. "Go out on campus, jog, go eat, do whatever until your next class."

The males all stood up and left the class, leaving Dr. Morgan with his 12 programmed female students.

"Ellie, when I wake you, you will not question why the boys aren't here. Instead, you'll challenge my claim of post-hypnotic suggestions and triggers working on people. The more bizzare things that happen to your classmates, the more adamantly you will deny it has nothing to do with hypnosis."

The other girls already had triggers in them, so all he had to do was wake them all and watch the magic.
