Ok call me retarded (I know most of you will here, but im being honest) but why do you fight Riku in KH2? The second time you go to the land of dragons, you give chase to an organization member, after you see the heartless coming over that hill, the organization member pulls out the soul eater, the weapon Riku used in KH1. He also went on to warn the emperor that heartless were attacking, but said that "three wise guys" had it under control, refering to Sora, Donald and Goofy.
I know it may be a stupid question and all, but i honestly dont know :S
