And then that is a good argument for why things feel inconsistent--if it was envisioned a certain way, written a certain way, and then someone went back and rewrote it.

Also I am very curious about where I can find details of the production history. Over the years, I've become more cautious about including such details if only because I've come from other fandoms that lied about their secondary sources. So now, I try not to mention anything unless it is a primary source.
