A/N: This plot bunny struck me one day, and it just wouldn't leave until I got it down on paper. It makes a strange amount of sense-- to me, anyway. I hope you enjoy.

Butterfly Effect

Lelouch was accustomed to seeing brutality against Elevens. It had always rankled him, but he had been too concerned with his and Nunnally's precarious situation to do anything about it.

But now...

Now he had the Geass, and that changed everything.

It was evening. The student council had convened after school to discuss something inconsequential, but it had taken several hours longer than expected. It had put him in a foul mood, and he was almost happy to dish out a little justice to whatever arrogant, snot-nosed noble had decided to act superior that day.

As he approached the scene, he noticed something peculiar. He was certain that, only a few moments before, the Eleven had been on the ground. But he was gone, as if he has never been there at all. The noble and his cohort looked decidedly confused.

Still, his eyes had certainly not deceived him. The fact that the Eleven was abnormally quick did nothing to detract from the noble's guilt.

He still needed to be punished.

"Excuse me," called Lelouch, feigning friendliness. The noble's bodyguard stiffened as he approached. "Do you happen to know what time it is?"

The noble, still shocked from the escape of his victim, looked at him without responding. Lelouch didn't need anything more than that.

He activated his Geass. "Forget the time. I think it would be a very good idea for you to die, instead."

The noble's eyes took on the tell-tale glaze of one under Lelouch's influence. "Yes," he said, cheerfully vacant. "I shall die."

The bodyguard was no fool. He glared at Lelouch as his considerable muscles tensed. He began to advance, but Lelouch didn't miss a beat.

"You will forget this ever happened and walk away."

The guard complied.

Lelouch felt accomplished.

"You are special," said a heavily accented voice. "Did you kill him?" It sounded angry, too. And a little unsure.

Lelouch smirked. "So you're the one he was harassing?" He turned around to the owner of the voice. He was short, somewhat chubby, and wore glasses. Definitely not somebody who one would expect to be able to move with much speed. Curious, he thought.

"I did not need your help." The Eleven was frowning.

"No, you didn't. But this wasn't about helping you-- it was about justice." He activated his Geass. "Now, tell me exactly how it is that you can move so fast, and what it is that you are doing here."

"I have the power to warp time and space," said the Eleven in a monotone. "I am here to see what will happen if Takezo Kensei does not fulfill his destiny."

Lelouch felt his eyebrows shoot up. Warp time and space? Had he not known the power of the Geass, Lelouch would have thought he was lying. As it stood, the Eleven was definitely telling the truth. Even if he was clearly delusional.

"You honestly believe that you have the power to warp time and space?"

The Eleven's eyes were wide. "How do you know this?"

Lelouch smirked. "You told me."

The Eleven backed away. "You really are special." He paused then, thinking for a moment. "It does not matter," he finally said. "I will set everything right."

The Eleven screwed his eyes shut, as if in intense concentration, and vanished.

Lelouch stood there, nonplussed. But he quickly shook himself out of it. It had to have been some kind of trick-- an illusion, and nothing more.

He walked to his quarters, where he donned the attire of Zero. Because he did not know, could not know, that everything he did was ultimately meaningless.

Hiro Nakamura would see to that.
