A/N: This is the result of an assignment for school; write something about Chaos. Of course, being the weird little fangirl I am, I took that to mean Vincent's buddy Chaos : )

The song lyrics in every second line are from Butterflies and Hurricanes by Muse. It's just what I happened to be listening to when I started writing this. I wrote this in about 20 minutes, so hopefully that excuses the general crappyness of it: (

And by the way; I can't for the life of me remember what Chaos looks like, so I'm making this up ; )

----Chaos Theory----

Change everything you are

Yuffie kept running, hoping that if she ran fast enough, it wouldn't find her. She could feel her heart pounding against her chest loudly from fear and exhaustion.

And everything you were

She shouldn't have kept pestering him to tell her about Lucrecia.

Your number has been called

He had every right to be angry, of course, but she hadn't expected him to be that angry.

Fights and battles have begun

Not angry enough to loose control of the monster he hid within him, letting it break out.

Revenge will surely come

She tripped over a branch, and fell flat on her face.

Your hard times are ahead

She lay still for a moment, gasping for air and trying to hear… anything, really.

Best

Nothing but the sighing of the wind and the rustling of branches.

You've got to be the best

And then she heard it.

You've got to change the world

The snap of leather wings, beating overhead.

And use this chance to be heard

She rolled over, looking up at the star covered sky. There was nothing but stars and blackness…

Your time is now (time is now)

And one patch of darkness that was vaguely man shaped, with two large patches of the same inky darkness on either side of it, which could easily have been wings.

Change everything you are

And suddenly the shadow swooped at her, two glowing red eyes materializing within the darkness.

And everything you were

She yelled and fished an oversized shuriken out of her bag, throwing it at the approaching blackness with all her might.

Your number has been called

The blackness pulled back and screamed; an inhuman noise that made her cover her ears and gasp with pain.

Fights and battles have begun

Then it dropped straight down to the forest floor, landing with a thump a few meters to her right.

Revenge will surely come

Yuffie scrambled to her feet and backed away, keeping her eyes on the monster.

Your hard times are ahead

In the dim light she could see it's red and black, spiked hair waving slightly as it moved.

Best

It fell to its knees and whimpered as she watched, one clawed hand pulling at something that glinted on its chest.

You've got to be the best

Her shuriken.

You've got to change the world

She could see its pale blue, black lined face was screwed up in agony.

And use this chance to be heard

And then she saw its red eyes, filled with pain and looking at her imploringly.

Your time is now (time is now)

Her mind ground to a halt.

Don't let yourself down

This was Vincent.

And don't let yourself go

But it wasn't!

Your last chance has arrived

It was Chaos, the monster inside him!

Best

But the monster looked so human now, its sharp teeth clenched together in pain and eyes bright with pain.

You've got to be the best

Yuffie made her mind up.

You've got to change the world

She grabbed a healing Materia out of her bag and dropped the leather sack back onto the ground.

And use this chance to be heard.

Chaos looked up again at her as she gently pried his hand of the shuriken and told him to stay very still.

Your time is now

He flinched and flapped his wings once when she pulled the sharp weapon out of his chest, but other than that didn't move.

Your time is now…

Chaos tried to smile at her. It was a fairly good attempt for someone with a mouth full of points and eyes still full of pain.

Best

She was surprised when he spoke. She didn't even know he could.

You've got to be the best

"I'm sorry I scared you. I came out to stop Vincent hurting someone… And I followed you to make sure nothing happened to you…" His voice was deep and wispy, like he hadn't used it in a long time.

You've got to change the world

Yuffie was even more surprised when she realized she believed him.

And use this chance to be heard

She muttered the activation spell for the healing Materia she was holding, and watched as a green glow engulfed the wound on the demon's chest.

Your time is now

And then Chaos's whole body was glowing, and when the light dissipated, Vincent was left, bent forwards and gasping back sobs.

Your time is now…

Yuffie helped him to stand, and they made their way back to the small campsite, about twenty minutes walk away.

oOo

Anyway, sorry about the suckyness of this short little peice of writing. I might add another chapter on... but I probably won't. It depends if people think this sucks as much as Ithink it does. Thank you for reading!

Oh yeah, and notice that Yuffie started thinking of Chaos as 'he' instead of 'it' near the end. That's an attempt to show that she stops thinking of him as a monster.
