Riku had to turn his head away so that he didn't laugh out-loud at the actions of the boys. Oooh goodness though! They were so funny! They were so excited about talking to Sora; Riku just hoped they didn't get overwhelming.
"It is all true," Riku had to put in. Everything that the boys said and thought Sora did... was true. And Sora should be proud of what he'd done. If he didn't believe Riku, maybe he would start believing it if others started saying it too.
"The army will be home soon," Riku told the boys. "And some of the Trabians will be coming with them." Including his brother.
