Given that it's that time of year when the cable channels show Star Wars in entirety, this thread and your comment reminded me of a thought I had last year when rewatching Ep4 on cable. The amount of content that has come from throwaway one-liners that Lucas probably gave nearly no thought to is insane when you consider it. "I fought with him in the Clone Wars" has given us a whole movie in the saga, which then gave us a whole animated series, when then begat a handful of additional series. And that's just one example from one line. It's crazy to think about.
This is why I tend to roll my eyes at this sort of Tolkien-level analysis of the story and universe. It's just not a high-quality enough thing to really stand up to that sort of scrutiny. It's like talking about Jelly beans the same way you'd talk about wine. There's just not much there, and so much of it is just inventing things in the murk of the story.
