Ok I know it might not sound like it should be here but hear me out. Have you notice all the characters in the game has similarities to the main characters.
As the example i used Cloud and Riku. Both of them had a good heart but they went to the darkness. Like cloud joined Soldier and Riku joined the Heartless. Then both found out that was the wrong choice. As both didnt want to be controlled so the left everyone family and friends to be alone. Yet darkness was in the heart. For Cloud Sephiroth and Riku Xehabort's heartless. Yet they was able to overcome it but with a special person. For Riku Mickey and Cloud Tifa. Then after time returned to their friends as like family but still had doubts. Also the phrase from the Darkness is the same. I wont go until you are overcome by dark. Yet replied that they wont go back.
So the point is that their will be a chance if we know the charatcers besides VAT we can know a little about VAT.
