I doubt that they would just openly admit that the completely remodeled the entire love element in the first place, which leads me to also believe those letters are fake.

And the words 'presumably' and 'possibly' mean about the same as 'I guessed' and 'it might be true....' so your "award-winning" website there, might not be so accurate after all.

AND even if they INTENDED Aeris/Cloud relationship-strengthening after the infamous death scene, they no longer have any.

They might have had a few more scenes, but they didn't, which leads me to hypothesis that Aeris was killed due to an overall lack of respect/love for her character in the first place.

Either way, Aeris = dead and Tifa = alive. That alone wins us this argument, so you might as well stop trying.
