So I've been playing Persona 4 Arena a lot lately and came to notice the fact that both Margret and her sister Elizabeth have golden eyes, moreover these eyes have an eerie resemblance to the eyes of the Shadows that everyone had faced in P4 (Shadows as in the main bosses who reflected the Jungian archetype, not the usual monsters). This gets a guy thinking to who/what they are. Could they be Shadows? If so, whose? It is heavily hinted that they are nearly immortal and insanely powerful. Any thoughts? I mean there doesn't seem to be enough in-game explanation, so this is really speculation.
