You don't need a reason.

"Ah, Zidane. It is Garland here. I know you can hear me. It is just a shame that you cannot move. You understand, I cannot have you endangering all my best-laid plans." Where am I?

In Pandemonium.

Where's that?

On Terra, you fool. Y'know, the place you were created.

I was not created! I was born in Lindblum, and I was orphaned at twelve months.

Were you? *flash* I.don't know. I-I-I.don't remember. I.don't know. I-I-I.don't remember. "Yes you do. You only have to believe, and it will be so. Such is the power of the soul. Of course, you are a nuisance and as such, need to be dealt with. You need some help, and I, Garnet til Alexandros the Seventeenth, am here to help."

Dagger.?

You cannot defeat me, Zidane. I am you, and to beat me, you need to beat yourself. Can you do that?

Yes, I- *flash* No.

I am the Genome in you. Will you surrender to me? "Vivi is here to help you. You know, he's one of the most loyal tools that Kuja made. I can't believe that your brother came so much in handy. He gave me Gaia, and even I, with my intellect, have to admit that he had a stroke of genius in using Gaia's own Mist against it. What skilled use of what you have at your disposal!"

You will not get him to finish it, you know, Garland. He controls you more than you would ever know. Kuja has you by the scruff of the neck, and he will squeeze. Oh, yes, will he squeeze! He will tighten the noose, slowly, without you noticing, until it's too late to do a thing about it. Hahahahahahahahahahahaha. *flash* huh?

You forget, Zidane-or should I say Genome?-that Kuja is like you. He can be controlled, and if need be, replaced.

Who am I? "Zidane? Zidane? ZIDANE!!!" what? "Thank God you're safe! We thought you were dead. What happened? Helloooo? Zidane? Is anybody home? It's Eiko. The little kid? Nope. Nothing." How?! Help meeeeeeeeeeeeeee! Please! I need some helpppppp. "Vivi, what are we gonna do?" "I wish I knew, Eiko, but there's nothing we can do. He's the hero, and it's up to him to save himself. All we can do is.wait." You have lost! He is a Genome now. He can scream all he wants, but you will NEVER see him again. At least, not as he was. Noooooooooooooooooooooooooooooo!!!!!!!!! Brother, I need your help.

That was all it took. Zidane snapped. He lost it. His rage burned, and for a few seconds, Zidane was on top. He beat the Genome to a pulp in his mind's eye. "Help...only.few seconds." "Zidane!" "Kill..me.now."
