I realize Riku never died, but his heart HAD wavered between light and dark and my sig suggests. Because of this, the Keyblade chose Sora as its next wielder. By the end of CoM, Riku realizes he needn't worry about the darkness in his heart controlling him. Knowing that Light and Darkness are merely two pure sides to the same heart, he is able to reclaim his title has Keymaster.
(Actually, in Buffy the Vampire Slayer, there was always a full world of potentials. Only one at a time ever became the Slayer though. At least until the very end of the series...)

Ok. Assuming that this works, how does that explain Mickey's keyblade? And what's more, when Leon and the others were referring to the Keyblade, they referred to it as just that: "the Keyblade". They said that the Keyblade chooses who wields it, but nothing they ever said gave any indication that there were more than one, or that the Keyblade master could wield two.

Also, having just finished Reverse/Rebirth (booyaka!), I can state fairly confidently that Mickey and Riku are not members of the Organization. My reasoning? They just got through smacking around a castle full of those jerks, and yet as they leave to go down the road to dawn, they are both wearing Organization cloaks. The Organization had just lost Vexen, Lexaeus, Zexion, Marluxia, and Larxene. The only member we know is still there is Axel (and his mental stability seems rather questionable, as do his motives), and possibly DiZ (though why he is allowed to be in the Organization without wearing a cloak, but Mickey, Riku, and Sora are automatically assumed to be in the Organization because they are wearing cloaks is beyond me). We know that there are at least twelve (probably 13 according to the current theory [the same number as the number of floors in Castle Oblivion, hmm...]), but even so, the Organization just lost nearly half of its members. Mickey and Riku had just fought two, and they knew that Sora was fighting others. I really don't think they'd go volunteer to sign up, especially since by the end it still doesn't seem that DiZ has explained how he knows the King yet.
