Konig never met his dad, he had been gone for years, for reasons his mom never told him

Conveniently, the day his dad came back and was even supposed to pick him up from school. That day, he had snapped and gotten into a fight with one of his bullies, meaning he was now in the office.

He heard what he assumed to be his father arguing with the bully's parent, and after a few minutes you walked out the room.
