Once Mackenzie arrived in her dorm, she brought Jack out and set him on her bed. "Listen, I'm going to get changed, so you just wait here, okay? Once I'm done, we can get going," she winked. She turned around then went to her closet. Jack, feeling there was no better time to get back to normal and leave, pulled the shrink ray out of his back pocket. He looked up, confirmed that Mackenzie was still preoccupied, then set his shrink ray to normal size and activated it. Like all the other times before that he's used it, Jack was instantly transformed. This time, however, something was a little off.
Mackenzie finished changing and turned around to snag Jack and get going, but gasped in surprise when she saw him. Jack was no longer an inch or two tall, he was now about two or three feet tall. At the same time, she noticed Jack was fidgeting around with some sort of device. "Uh... Jack? Is that you?" Mackenzie asked, completely perplexed. Jack looked up and froze. "Uh, yeah," he nervously chuckled. "Something happened". Mackenzie stood in place, staring at him in confusion. "No kidding. So, uh, is this your normal size?". Jack shook his head, the awkward atmosphere increasing every moment. "Um, no, this is about half of my normal size. But with that being said, now I can leave on my own, so I think I'll do that". Jack hopped off Mackenzie's bed and began walking to the door, but nearly walked into the girl's crotch as she stepped in his way.
"But why on Earth would you do that? The sorority is still expecting you at the party," Mackenzie smiled. Jack read her face and figured she still appreciated him at this size. "But, uh, I'm bigger than I was before. And I have stuff to do back at my dorm, so, uh, I should walk back". Mackenzie picked him up, holding him in both hands. "Nonsense," she laughed, "you can totally come and hang out with us. Let's get going, then, don't want to be late". She tucked him under her arm and pressed him against her side, then exited her dorm. Jack kicked as best he could, but that only caused Mackenzie to hold him tighter. "Oh my lord," he thought, "I really hope no one sees this. This could singlehandedly ruin the shred of dignity I have left". Luckily for him, no one did see it. Once outside and in the parking lot, Mackenzie opened the back seat to her car and tossed Jack in. She was about to close the door when she realized something.
"Oh yeah," Mackenzie giggled, "You probably need like a booster seat or something. Here," Mackenzie pulled out a few sweatshirts from under the driver's seat and made them into a makeshift booster seat. Jack stared at her. "You don't really expect me to use that, do you?" he asked. Mackenzie shrugged. "Well, you are under three feet, it's only natural". Jack rolled his eyes and began moving over to get on it, but instead he hopped over the seat and jumped to get out of the car. He fell right into the waiting arms of Mackenzie, smacking face first into her chest. "Aww, Jack, you're such a lover-boy. I think that would be great for you at the party," Mackenzie giggled. She then placed Jack onto the "booster" seat, strapped him in, and quickly made her way to the driver's seat, where she turned on the child safety lock on, ensuring Jack wouldn't be going anywhere.
The minute Jack heard the locks turn on and Mackenzie's door shut, he knew he was likely doomed to go to this party. After leaving the college campus and driving for ten minutes or so, what happens?
