[He's going to avoid asking who Kairi is--that's the girl he likes. The one that's supposed to be in the memories, instead of Naminé.] But what I do know, is that somehow, you wound up in Castle Oblivion, just a few days after Sora had been lured there by a nasty group called Organization Thirteen.

[He pauses, the look on his face going contemplative.] It might be better to show you what happens, instead of telling you.
