Jon's first class was Trigonometry. This might be interesting. Both Kyla and Karyn were in this class.
Kyla was extremely good at math and science. But in this reality, she had the original Sarah's interest in school, which wasn't much at all. And now Karyn had the original Kyla's personality, so she had a great interest in school, especially math and science.
Jon took his seat and watched Kyla walk into the classroom, with an air of importance about her. In this reality, she was now in fact the most popular girl at school. It was kind of funny, though, because even though she didn't have big breasts or blonde hair, guys were still drooling over her. Jon guessed that the rest of her appearance made up for it.
Then he watched Karyn walk into the room. Jon still couldn't get past how startling her appearance was now. She sat down a few seats down the aisle from him. He turned around and said "Hi, Karyn."
Karyn looked up at him, through her thick glasses. "Uh ... hi," she said, shyly. She seemed a bit confused, probably because Jon didn't usually talk to people like her. Karyn's memories were different now. Jon had never become her friend, let alone best friend. It was strange for Jon, not being able to talk to her, who he still viewed as his best friend.
Then Mrs. Watson, the teacher, walked into the classroom and the class began.
