i still think that a keyblade is the wielder's heart in weapon form which would explain why it can be summoned at will and why sora had it so easily stolen until he looked inside himself. If this is so then why the hell wouldn't he be able to summon two. The stronger his heart gets the more keyblades he can wield. Hell, maybe he'll get a keyring and start swinging around five at once.

Peace out and :rock:
