Roxas would explain as much as he could as soon as they caught Sora. In the meantime, he was wondering where Sora could be headed given that he'd said something about a costume. If he knew his way around well enough, Roxas would have headed to the most likely place to try to head him off, but there was no such luck right now.

Hopefully, whatever had gotten into Sora wouldn't lead to any fighting, but maybe that concern was better left to when they caught him...
