Honestly, I didn't care about the continuity issues like "How could the station be Rakatan technology?" or "How could the Umbarans affect the lightsabers?". Both of those issues are far too vague to complain about in the book overall. We don't know everything about the Rakatans. Only the Star Forge, really. That doesn't make us experts on their entire history and all of the technology they were ever able to create. And the Umbarans cut off the lightsabers. I actually thought that was cool, despite the fact that it grates against the powers of Ysalamiri. Granted, that is true. But again, it's vague. No one ever said the Umbarans and the Ysalamiri were using the same technique.
Anyway, regarding Jaden being transferred to a clone at the end...I thought this was a brilliant twist, because I didn't expect it. What I did expect, however, was for Jaden Korr to be a clone from the beginning. Like...all this time he's been a clone and we never knew. I expected Soldier to be the original for two reasons. One, he was the only one able to resist the Umbaran's power. Even Jaden couldn't do that. And at the very end of the book, it clearly says, "He had met his clone." What in the world did that mean? The Iteration was not a clone of Soldier. And, to our knowledge, neither was Jaden. So what did this mean?
So...my theory. Soldier is the original Prime. When it was realized that he was a perfected specimen, Jaden was cloned and planted as a normal human being in a sleeper cell type manner with his uncle. In this way, he was able to build his own lightsaber and such. From here he spent the rest of his life doing what we know about already. In growing to be a Jedi, his connection to the Light Side overrode his training as a sleeper cell and he was no longer susceptible to the code phrase. This explains several things:
1. Why Soldier is the only one that can resist the Umbaran's power (this ability did not make it through the cloning)
2. How they had Jaden's DNA so early
3. Why Nyss thought Jaden was a clone
4. Why Soldier thought Jaden was a clone
I realize there are several fragile parts to my plan, like how Jaden overcame the code phrase and how he was planted with his uncle. But any variation on this theory where Solider is the original greatly intrigues me. Having Jaden Korr be the original presents me with more questions than does having Soldier be the original. So that is my current thinking. Call me crazy, but...I kind of like it.
I loved Marr being able to stop the lightsaber. A crazy power, yes, but let's just call it a talent. Satele had it, we know. So why can't Marr? How come Luke and Co. couldn't use this power? Meh...you can't have everything.
@Life: Ha! I also wondered about the Umbarans having said relationship, and I thought myself disturbed for doing so, therefore abandoning the thought. But the fact that you also thought so and had it confirmed cracks me up! And further disturbs me.
I really hope for a sequel, since I can't see how they can avoid one at this point. Surely Jaden being the Iteration will come back to haunt him at some point. Perhaps they wanted Riptide released now and Apocalypse pushed back so that this could be incorporated? No idea. Just a thought.
