Jimmy put a hand to his head and looked up. Everyone who had been watching the fight had run away. He saw Cindy racing down the stairs towards him.

"Are you ok?" she shrieked as she hugged him.

"Yeah, I'm fine," he lied as Cindy helped him up. "Did any teachers see?"

"I can't believe that they didn't. He tried to stab you!" Cindy yelled as she remembered what had happened.

"Keep your voice down. The last thing I need is to be suspended," Jimmy explained to her.

"Come on, we've got to get you to a nurse," Cindy said as she led him to the nurse's office.

"No way. She'll know that I was in a fight and get me in trouble. I'll just clean myself up in the bathroom," he said as he slowly limped in the other direction.

"Jimmy, how the hell did you learn to fight like that? You were like, like, a ninja or something!" Cindy incredulously asked.

Jimmy paused for a moment. "Ah, hormones. Must have been a muscular growth spurt or something," he said as he walked down the hallway.

Cindy leaned against the wall and thought of something. Didn't he something about having to train to save the future last year? Maybe he wasn't joking.

Half an hour later Jimmy and his friends were in history class. He looked across the room and saw John reading a book. How the hell is he in all of my classes?

Cindy was sitting down in her seat a few rows away from Jimmy. She was writing in a notebook.

Jimmy and John got in a major fight this morning. And I'm not exaggerating. John kicked Jimmy down a flight of stairs and tried to stab him! Jimmy got beat up pretty bad.

But it's weird. Jimmy was really holding his own until he fell down the stairs. I've never seen anyone fight like that before. He was better than my tai-chi master. How in the world does he know how to fight like that?

Last year Jimmy was acting really weird. All he ever did was workout and meditate. He never hung out with his friends anymore. All he ever did was stay in his lab. I kept asking him what was wrong, but he refused to tell me.

Then one day I was with him in his lab when he passed out. he woke up ten minutes later with a glowing ball in his hand. He didn't have it with him when he passed out. It just, appeared.

I asked him about it, and he said he was ready to tell me what was going on. He said that he had had a vision with his future self. He said that he had to train because his future self had told him that the world was going to be destroyed, and only he could save it. And he said that the changes that would cause the world's destruction would be happening soon.

I yelled at him. I thought he was lying to me, covering up what was really going on. I mean, can you blame me? That story wasn't possible! But what if he wasn't lying? What if he was telling the truth?

That burn on his hand. How did he get that? And the ball that appeared in his hand after he passed out. Those fighting skills, he would have had to train for years to become that good. And John, I see Jimmy shudder whenever he walks by. And John is pretty mean. Could he be the one who will ruin the world?

Do I actually believe all of this? It seems to crazy too be true. But Jimmy's story seems to make sense now. Maybe he wasn't lying. I have to check this out.

Cindy closed her notebook as their teacher handed out an assignment. She couldn't help but stare at Jimmy the whole time, though. What if he wasn't lying?
