I've been thinking more and more about this title and how it might fit in with some previous lore, and it brings me back to the prophecy of the One who would bring balance to The Force.

In the prequels Yoda and Mace Windu spoke of the prophecy of the Chosen One who would bring balance to The Force. Having seen the complete story of Anakin Skywalker, I think that it's likely that he may not have been the Chosen One. He was a Jedi who turned to the Sith, but eventually turned on the Sith, destroying them. In the process he was killed, leaving Luke as the last Jedi. So was the prophecy achieved? It doesn't seem that way since Luke remained as a light side Force user.

I'm wondering if it's possible that Rey is actually the Chosen One. If Luke is truly the last of the Jedi as Yoda said, will Rey become something else?  It's very clear that The Force is with her.  She took on Kylo Ren, who had both Jedi training and was strong with the Dark Side, and Rey had ZERO Jedi training.  It seems that in light of how the Jedi failed in the prequels and Luke's new generation of Jedi fell, maybe Rey is destined to be something other than a Jedi, perhaps something greater?  Is it possible that Rey is destined to become a new type of Force user who can harness both the dark and the light, truly bringing balance?

They are breaking with wording tradition. It should have four words not three. Each middle movie had four words.
