I am all in on the Jar Jar sith theory. Specifically I think Lucas set him up to be Darth Plagueis, but saw the backlash to the character and came up with something else. It just seems to much a lot of sense, especially when you look at things Jar Jar does in EP 1 that look suspicious and had to be deliberately animated. I really thing there is something to the theory, as crazy as it sounds.
Oh I donβt dispute that Lucas intended him for comic relief, I just believe that he originally wanted to reveal that it was all an act in ep 2 or 3, but then changed his mind after the character was hated so much. Thatβs my headcanon at least.
