once they left for high school on the bus when they were picked up at the bus stop that it was an hour drive as Jacob and Krystal both headed to school. when they reached the school is where Jacob warned her about something when they both got off the bus and headed for school. "now look sis, you may look and act the same to others, but if any changes happens without a good explanation to them, then i'll have to punish you as i'll also have to removing their memory of the act."
as they both entered the school grounds that Jacob was once a nerd back then, but he has changed since then. the way he was treated by other school classes to be like a normal high schooler that it caused some trouble for others, but not a lot of it. thinking about his first class at school that he remembered about his friend as his friend wanted to be something else. something that was different.
(this is where you decide who is Jacob's friend is. feel free to add your own story line up. thank you and have fun reading.)
