When I couldn't understand why someone was acting in a particular way at a particular time, it turned out that I just hadn't been looking deeply enough. In the end, it all turned out so clear -- and for me, anyway, so true -- that the character arcs have the same tragic inevitability as the mechanics of the plot. In a very real sense, they are the mechanics of the plot. The question of "Why?" is really what the story is about. In a lot of ways, it's really what the saga is about, and I think that's something that even the hardest of the hardcore fans have been missing all these years. There's really a lot more going on under the surface than they ever suspected. That's something I think this film is going to bring home to them finally. He could be talking about anything, here. Doesn't lend or detract from your theory because it's so vague.
