The old school's gymnasium still smelled of sweat and linoleum. Sam felt a vibrant spark within him. There she was, Grace, coaching a group of kids. He felt that familiar thrill, that feeling of being on the cusp of something… fun.

He discreetly, slowly, crept into the gymnasium, pulling down a basketball net. When he was certain he'd done the job, he sprinted away.

He watched from behind a window as Grace turned around, confused. He stifled his chuckles, pressing his lips tightly together. He whistled innocently.

He pushed the door open. "Everything alright?" he asked, affecting an air of complete innocence.

She looked at him, puzzled. "Do you know anything about the basketball net?"

"Me? Never." He grinned. "Remember that time we swapped the Principal's shampoo for dish soap?"

She gave him a blank stare. "No, I don't."
