I pretty much knew what was happening about half way there, but they made a very simple plot extremely confusing deliberately. Throwing in J1, J2 and J3 plus their personalities just made it look like the guy had multiple personalities. The confusion is not around what was happening, but why some of the things were happening. Was the Archive Company picking his brain? Why did J2 behaved as it did. What was the transfer? It just leaves you frustrated because you have no answers.
