For me Xion is connected to Sora, she is connected to him cause she uses the KK like Roxas.I dont know how she wield it if Roxas is using it to.She came to the Org. before Roxas but maybe because Xion is not a nobody thats why it's still org 13, she is maybe a memory from sora because namine said about "she cant resist it" or something. So maybe if sora will regain his memories,Xion would vanish, just like roxas.So she wears her Org. clothes to hide her identity to run away to her faith. But to the Org.,they would use her to crete the artificial KH and Xion has no idea. So maybe the one who convinces the others to betray was not xion but roxas.
