XD;; I only meant to write the 'anti!Sora calms down Ansem!Riku' bit, but then my inner plot-bunny wanted to know why and how. I drew the line at Radiant Garden, but if they do go there first, they'll meet a pretty freaked out Cloud and an aloof, smirking Sephiroth. Everyone else, pretty much gone the way of most of Destiny Island's inhabitants.
The thing is, Riku and Sora are still semi-okay because they have 'bleed-off' forms for when their Darkness overwhelms their Light. The Princessess don't have any Darkness, so they're not going to be affected by it, and Cloud and Sephiroth are sorta kinda already divided along Darkness/Light, if you read cannon at a certain slant.
I figure the Heartless this time around are going to be much tougher, if not (fortunately) much smarter, and no pesky Nobodies will be produced.
I have noooo clue why this is happening or who's behind it. XD;
