In front of Jack was a full row of seven students. There were three boys, one located on the far left, the other to his right, and the third diagonal to Jack's right. Of course, that left four girls filling in the gaps between and around the boys. With these options, Jack thought that it might be interesting to try his shrink ray on someone else for a change. Granted, this could be considered extremely unethical, but Jack figured that it would be very difficult for someone to identify him as the culprit of the shrinking incident. Weighing the pros and cons of what he had planned, Jack concluded that he may as well go through with his actions.
In a moment's notice, Jack activated his shrink ray, and in a moment's notice, he saw that the boy diagonal to his right, along with the backpack on his back, disappeared, confirming that he had been the one affected. Now that he was shrunk, though, the boy was no longer visible to Jack because the back of the seat concealed his figure. Jack sighed and put his head on his desk. "What have I done.." he thought. Yeah, it was cool to finally have experimented on someone else, but it probably would have been a better idea to try it out on someone he knew rather than a random stranger. Luckily, the students around him had been too focused on the lecture to have noticed the boy's sudden disappearance. Now knowing that what he did was wrong, Jack slipped the shrink ray back into his bag and went to work taking notes.
Not long after putting the shrink ray away, a figure entered the lecture hall and quietly made their way to the row in front of Jack, noticing an empty seat. Jack briefly glanced at the person, who appeared to be a girl who was on the larger side and had her body accentuated by rather tight clothing. Thinking nothing of her, Jack glanced back down at his paper and continued writing. The girl, meanwhile, asked if the open seat was available, and the girls already sitting, who briefly looked at the open seat in confusion not understanding how the boy sitting there no longer was there, gave her permission to sit down. As she made her way to the seat, Jack peered up. When the girl pulled the chair aside, Jack noticed the small form of something on the middle of the chair. He gasped.
"That's the guy," he thought, exasperated. There was nothing Jack could do to help the poor lad, though, as the large backside of the girl threw a shadow over the man and descended onto him quickly. Jack merely looked on as the boy was completely engulfed by the girl's leggings and heard the faintest crunch. He grimaced. Having been shrunk himself so many times and attaining a greater sense of endurance, Jack hoped that the same applied for the guy who now was being dominated by the large girl. Jack looked up from the chair to the back of the girl's head, which was covered by a silky, dark brown hair. He was tempted to tap her on the shoulder and notify her of the fact that she sat on something (or rather someone), but Jack felt that she might consider him crazy.
Instead, he meekly went back to taking his notes, listening to the creaks and groans of the girl's chair as she shifted around. Jack shuddered. For the rest of class, he had a hard time focusing as the ever so slight cracks and crunches were amplified to him, reminding Jack of his mistake. When class finally ended, Jack quickly packed up, but remained in his seat for a minute. When the girl in front of him stood up and began walking away, Jack looked at her seat and noticed that the small form of the guy he had shrunk was no longer there. Fearing the worst, he peered over to the girl as she was exiting and saw a malformed object on the right cheek of her leggings. After getting lost in space at the sight he saw, Jack eventually lost the girl as she flowed into the large crowd exiting the building. With that, Jack grabbed his things and exited as well.
What does Jack do in response to what he had done?
