— What about when Riku looked upon [Ansem] and dived into another world, was it assumed he’d join Organization XIII?
Nomura: Since they knew he’d wake up soon, it’s reasonable to assume as much, but that wasn’t necessarily why the Organization had guided him. Still, they weren’t ready to completely give up on Riku, they wanted to win him over into the Organization. However, Riku had developed a resistance to darkness and as a result, they gave up.
— What about Xemnas and Ansem, essentially they weren’t inside anyone, was it due to circumstances of the worlds of sleep?
Nomura: First off, when Young Xehanort made contact with the Brown Robed Figure, that is to say, the Xehanort who called himself Ansem, his abilities were transferred to him. As a result of Master Xehanort tossing his physical body, he was able to exceed time, and this power was carried into the Brown Robed Figure. Thus when Young Xehanort made contact with him, he gained this power. Possessing this power. Young Xehanort functioned as a “portal”, summoning Xemnas and Ansem each time they appeared. That’s why Young Xehanort was there whenever they appeared. Additionally, when Sora and Riku dropped into the worlds of sleep, simultaneously Young Xehanort himself goes into the world of sleep.
