In the Grand Hall, they see Leon, Yuffie, and Aerith
Sora: What are you guys doing here?
Yuffie: We came in Cid’s ship.
Aerith: This is our childhood home. We wanted to see it again.
Leon: It’s in worse shape than I feared. It used to be so
peaceful...
Aerith: Don’t worry. If we defeat Ansem, all should be restored.
Including your island.
Sora: Really?
Yuffie: But, it also means goodbye.
Aerith: Once the worlds are restored, they’ll all be separate
again.
Yuffie: Everyone will go back to where they came from.
Sora: Then I’ll visit you guys with the gummi ship.
Leon (crossing his arms): It’s not that simple.
Yuffie: Before all this, you didn’t know about the other worlds,
right?
Aerith: Because every world was isolated. Impassable walls divided
them.
Yuffie: The Heartless destroyed those walls. But if the worlds
return, so will the walls.
Leon: Which means gummi ships will be useless.
Sora: So you’re saying we’ll never...?
