Just me rembling because I have nothing better to do. And just because my mind is clouded by pain because of my chronical pain so.
But just hear me out. Don't know is this was discussed before. But I find interesting the parrallel between two cinematics in KHUX and KHDR. They both have the same name "Fall to Darkness".
In KHUX, it's the end of the world everything is falling apart. Darkness is here and try to influence the Player to betray their friends so they could invade other worlds. And the Player will use the Darkness to play the vilain, fight their best friends to save them and to trick Darkness. The Player is trying to save all they have.
While on KHDR, Baldr lost his sister, and think he is responsible for the disapearance of their friends. Darkness will use him to put an end to this world of Light that was prosperous.
Two characters. While one had their world crumbling did everything to save their friends. The other lived in a nice world but lose everything and was mislead to destroy this world. In the end they were fighting two friends. A friend had silver hair and the other black hair. In the end it's the one with silver who will end the life of the one possessed by Darkness. The first one will not hesitate to do it to protect his friend. While the second hesitated, but stilll did what has to be done.
Even if Baldr was like a mirror image of Xehanort and offered a path of what could have happened to him. I like the parallel between him and the Player in those scenes. Like an ouroboros, things will repeat themselves.
