this is a theory pretty centered around something i thought everyone noticed, but nobody mentions. xion has a very large possibility to be made of way more then soras memories. sora, at the tme xion was created, had memories of terra, aqua, and ventus in him.(unless im misunderstanding the way he has the painful memories and how he got them).i think xions face wasnt created from his memories of kairi, but of memories of ventus and aqua. her hair is obviously more aqua then kairi, and sora has ventus' face from the whole heart connection,so.... also, if im right, this complicates ventus' hurt being mended. for sora to wake up from heart sleep, he needed his memories back from xion. so, now that xion is back with sora, wont ventus need his memories back from sora to wake from his sleep?(along with his hear, of course. lol)
