So, remember when I had the brilliant thought of making a Geezer!Saix to serve as a love interest for Master Xehanort? Don't worry kiddies, I probably won't do that, because a crack theory to end all crack theories has dawned upon me:

I now know how Kingdom Hearts began. o.o

The dark knight seen fighting alongside Master Norty is, in fact, Isa in another life. He was a loyal and loving subject of the lord of his world, obviously Master Xehanort. But this same-sex relationship and dramatic age difference was looked down upon by the public, so they were shunnn~ned! Three particular intolerant bastards (Terra, Ven, and Aqua) began a violent resistance in order to find a lord of their liking. Xehanort and Isa's anger was great, just like their strength, so they went around killing everyone. Soon, it seemed to be down to just those three said bastards.

Xehanort just wanted the best for himself and Isa. He accepted that they couldn't live in peace in this life, so he took Terra's body, which was sufficiently young enough for him to use in the next life, where Isa would be waiting. They may not remember each other, but without a doubt, they would be reunited. As other people, as Nobodies, as Heartless...

I bet Nomura would die laughing if he ever found this. :3
