James used to be one of the victims of your bullying in middle school. This looks to have some impact on his mental health.

By your sheer luck (or unluck), you've both been placed in the same class, in the same high school.

You're walking down a hallway to your locker. A guy shorter than you purposely bumps into you, pushing you away. He's glaring up at you with fierce eyes and a smirk. This kid got some ego. But you recognize him. It's James. How unfortunate.

"Revenge is sweet, isn't it?" The guy walks away.
