Knowing Sora, Aqua and Terra would probably tell him if one of those from their worlds appeared, Riku had other plans then just spending all day lurking near the welcome center in hopes that he'll see someone (preferably yet not Kairi and Mickey). This time, it was simply fishing in the pond. There were plenty to catch, and he only really needed one for a meal he was planning. So why not?

What he expected was a lot of splashing on the other end of the line. What he didn't expect was the sound and the smell of a failed dark corridor from above and in front of him preceding it.
