Although Riku somehow saw her in Dream Drop Distance, he couldn't remember her, even though I thought he'd be the one person that could. I guess that's what the scene when he was fighting Rosas was about. But, isn't she on the list of people Sora needs to save? How can he save someone he can't remember? And when Axel woke up as Lea, didn't he see Xion in the dream/flashback thingy he was seeing? And I believe the organization and data-namine should remember too, or at least be aware, since Roxas definitely wrote about Xion in the journal he left. I'm scared that the Organization DOES remember Xion and they're gonna use her as one of the 13 darknesses.. And nobody will try to save her because no one can remember her .. :'( (sorry favorite character)
