"A D?" Liam stared at the grade, which seemed to wobble and distort. He burst out laughing. It was a nervous, breathy sound, but it quickly morphed into something else entirely. He began to picture himself, as if in a movie, starring in a hilarious misadventure of epic proportions.

He grabbed the nearest textbook and began using it to beat a rhythm on the desk, the sound echoing through the otherwise silent study room. He was a conductor, and the textbook, a drum. He needed a whole orchestra.

He took a deep breath. "Well," he whispered, a smirk gracing his lips. "Let the games begin." He imagined himself as a detective, on the case of the missing points. He began mentally preparing to make his case.
