Go to the principal's office

As Billy looked around, it occurred to him that Ms. Hoover had plenty of guys to choose from if she needed more. Besides, he could still be the one to fill some of her planning period... And wouldn't it be better if he could do so with more experience of his own, so that they could each take time as the teacher and student?

Finalizing all of these thoughts, Billy stood and headed for the door. He was initially worried about someone trying to stop his exit before the class concluded, but simply used his new power to strike that thought from everyone's minds. He then left closing the door behind him to make sure he got to have this experience alone.

He then made the necessary turns, and soon arrived at the principal's office. Before opening the door, he smiled, enjoying the fact that his many previous trips there allowed him to arrive without considering directions, so he could instead enjoy working-out the possible things he could do once he arrived.

He opened the door, and there sat Jessica. It appeared she was almost fully recovered from the sweat and other effects brought on by her actions in the classroom. Ah, well, Billy thought to himself. We'll change that shortly.

"Billy!" she said when she saw him close the door again without anyone else following him in. "I thought I was going to be joined by the principal."

"You would," Billy answered, moving behind the principal's desk. "That's probably what Ms. Hoover would have planned, too, except that Principal Rooney is off at a meeting with the local Administrators."

"Oh," Jessica replied simply. Billy had to admit to himself that he was surprised by how easily she fell for this line. "Why did you get the job?" she asked.

"Well, it was sort of a mistake," he continued. "I got up to head to the restroom, and she thought I was coming to follow you. Then, I told her what happened between us right before you left, and she thought I might as well fill in for Mr. Rooney, especially since this is all a result of me and my Magic Pen."
