"So, use the slope-intercept form to find the y-intercept," Mr. Heracross told the class. "Eevee, can you demonstrate to the class problem #12?"

"Sure, Mr. Heracross," Eevee said and she jumped out of her seat. "The first step is to substitute the x-coordinate in the x part of the slope intercept, and the second is to... no... wait..."

Mr. Heracross shook his head. "Can anyone else solve this problem?"

Litten pushed open the door forcefully. "Sorry for being late," he blurted out.

"Litten, I didn't know you were coming to school today," Mr. Heracross said dryly. "Go to the office and get a late slip."

Litten dropped his stuff next to his desk and walked out.

He later stumbled through his classes, rushing through quizzes and freezing on problems he thought he would never miss.

 When the day was over, Litten took the bus home and collapsed on his bed. Tomorrow will be a better day.
