Well, as far as they knew, Mickey wasn't here with them. But it was probably better to assume that he wasn't here than that he was. If only because they still weren't sure about how they got here.

As for Kairi's actual question though, Aqua can't help but shake her head. "Honestly, it's mostly what we're doing now. Walk in a direction until we come across something that requires our attention. Though we usually do end up close to where we need to be whenever we land on a new world."

Which obviously wasn't the case here.
