I don't have much proof in this, but I do have a theory. First of all, in KH:COM, did Zexion really die? I know it seems like it did, but how can we be sure? In Proof of Existence, perhaps? Wrong. In that room in kh2, it has the cloaked Schemers grave, but no picture of his weapon, and the panel isn't red. The panel looks black, and broken. Could Zexion have come out of his grave? Did he ever really die? What do others think?
