I haven’t watched any of the commentaries, as I’m enjoying (for once) having something I can’t predict be unspoilered also. (Although I just discovered spoilers show up when you quote. Ah well. I only saw the first sentance, and I sort of thought that anyway. Still, bummer that it’s out there! I hate commentaries with spoilers!)
Part of my delicious confusion on the issue is that multiple characters fit both avatars, and the description of the avatars themselves are interchangable (A good guy who does bad things and a bad guy who does good things - well, duh! Who is that NOT describing?) Pair that with a screenwriter’s love of a good twist, and I’m not certain things won’t shift again and again before they finally settle.
Still, with the amount of last-minute edits and changes to the script, I’m not even certain that your spoilered commentary will remain true! It seems as if even the storywriters don’t know exactly where their muses are leading them.
