Maybe this was asked before but how exactly does this Roxas with the keyblade thing work? Are his keyblades the same as Sora's? or are oblivion and oathkeeper each their own, separate from the KK?(and I don't mean it literally btw) If they are the same, then how could sora also have the keyblade? If they aren't, then why would Roxas and Sora have the same ones? Is it mainly for symbolic purposes or what?
