Kairi: So, suppose you get to another world. What would you do there?
Riku: Well, I haven’t really thought about it. It’s just… I’ve always wondered why we’re here on this island. If there are any other worlds out there, why did we end up on this one? And suppose there are other worlds… then ours is just a little piece of something much greater. So we could have just as easily ended up somewhere else, right?
