Forum:Xion, the replica program, and the organization

i have a couple questions. first, i know that roxas saw xion as herself, and xigbar saw her as a hooded doll the as ventus, but who did every one else see her as, including riku? and can imagine why they wouldnt tell demyx about xion, since he would only mess it up, and i know that they wouldnt tell marluxia or larxene and obviously roxas, but why leave xaldin and luxord in the dark. and were lexaeus and zexion told? and does axel only know because saix told him?
