See Who?

"Hi, Jon," a voice said from the entrance to the classroom. "Did you just get here?" Jon turned and saw Lydia Warren, the other teacher for this grade. "Yeah, I did," he said, watching the other teacher walk over to his desk. She smiled, then said, "So...it's been almost a year now, right?" Jon nodded, yes. He almost frowned, having trouble remembering what was so important that happened a year ago. He didn't want Lydia to know something was bothering him. "What are you going to do when you see him?" She asked.
