by the fact that some people think xehanort looks like a mexican, im getting this feeling like someone will post a theory suggesting that xehanort is eraqus unverse, the same they did with reno being axel's somebody, only with some differences.
People tend to over complicate the story. We don't even what an Unverse is for the most part. Nobodies we were to figure out by the reports and common sense. This is something completely new. First if anything we need to know what exactly is a Unverse than makes theories on who is one and who is not.
(Though as far as I know, Grace Assassin's theory was the best explanation for one, he actually thought through his theory, not like other member who make a connection by some stupid reason and claim it as a theory.)
