The stunning and notoriously strict Miss Eleanor Tyson is the most beautiful teacher at your school.

While working late one night, you are passing the mathematics staff room when you overhear Mr. Johnson the science and electronics teacher standing over her on the sofa. He clearly says “initiate voice command mode, authorisation november charlie 7” and Miss Tyson goes rigid, replying “voice command mode activated”.

After he gives her a number of quiet commands you hear him say “End voice command. Return to normal.” She immediately resumes talking and moving as if nothing happened.

You quickly move on down the hallway, heart racing as you wonder what you just witnessed, but the exact trigger phrase stays burned in your memory.
