[Okay, something's really wrong. Either the kid's an excellent actor, or that's real pain there, and Axel doesn't like it. Less because Riku's in pain (really, the kid deserves a good headache for this one, he thinks) and more because the idea that Riku genuinely doesn't remember Xion is alarming. Riku was adamant about Xion's freedom to make her own choice to go back to Sora, and really, he's a smart kid, there's no reason he shouldn't remember this stuff. It was kind of important!

[So what happened?]

Riku, I'm not doing anything. I'm just talking. I don't have creepy voodoo powers that can send people headaches over a walkie. Though admittedly that would be a pretty cool power. [He shakes his head and points at him.] You have been to Castle Oblivion, and you kicked my ass there because I tried to go after Xion and change her mind. And whether I deserved it or not, it happened. You said you remember doing it, why would I lie about where?
