Interesting find. Especially the love triangle thing going on in the middle there. That explains why Sephiroth seems to have an affinity towards Aerith. The story we ended up with also makes sense and can still work if the original game HAD kept the storyline - and intact. You could make the story go like: Sephiroth searched for Aerith for the power of Aerith, and split the universe in some way. That rebirth storyline. Original storyline is Sephiroth search for Aerith for the power of Aerith, KILLS Aerith because I think he got what he wanted out of Aerith. This new leak, Aerith and Sephiroth falls in love, and makes things more complex. In my storyline idea, Rebirth continues, but Sephiroth falls in love with Aerith after the ending, and Cloud fights with Sephiroth over the love of Aerith. I don't think they'll do that in Disc 3/Part 3, because that will ruin the storyline of Rebirth. But he hadn't killed Aerith in one timeline, but in the other timeline she is alive in Rebirth ending.
Interesting article, nonetheless.
Nah I don't like making Cloud fights Seph over love of Aerith. Cloud should be on Tifa's PLOT all the way baby! lol
