Jay was smart, too smart to be socially accepted, but what really smart teen is good at that in High School anyway. Jay was also a devout believer in science, while everyone else watched Game of Thrones on sunday nights, Jay watched Cosmos. He was constantly missing social ques, constantly in deep though, constantly acused of not playing attention, while his mind raced with new ideas and factoids and science. So when Ms. Holloway started using magic, real magic right in front of him, he was a bit perplexed and amazed. He watched every transformation trying to work out how she was doing it. His first theory was a quantum transfer across realities, switching out one person for a similar person from another dimenision. If this was true then he would end up in the girl version of his reality, just as she would be in this current one, from there he could switch them back. This made perfect sense to him. He was very deep in thought when he was thinking this so he missed the moment when he actually changed.
It wasn't as he thought, Jade, as he was now known, was a very different girl, and Jay was certainly now Jade. She knew this, as she knew many other things...just not all of them as sciency as they once were. Jade was still just as smart, but now she was also pretty, and quirky. Guys and girls didn't see her absentminded, soical cue missing problem as a problem in a body like this, they thought it was cute, or funny, and so she had developed a personality of humor. She was a funny girl, on track to being a Manic Pixie Dream Girl once she hit college, but that would be completely by accident. Jade was amazed by what it was like to be a girl, it made her giggle, which made the girls around her look at her funny. In an attempt to cover for her faux pau, she said, "sorry I had the stupid idea that could fix this if I let it happen, but now...." she felt her boob, it was large in her hand. "I think we might be stuck for a bit..." she became distracted by her boob, it was new and exciting, and felt new, and....exciting. "boobs are werid." she said. Had it been a sit com and you were watching, you may have found it funny, but no one in the room did. Jon was up next.
