Right before Xigbar and Sora battle, he calls Sora Roxas. And he calls Sora Roxas again before he dies. Why does Xigbar refer to Sora as Roxas? Is when he says, "But MAN did it pick a dud this time" he refers that the keyblade picked Sora as a dud. But this also indicates that there was other(s) keyblade wielders. Do you think that he is refering to Roxas as the other keyblade wielder?
