Yeah, it was just a silly thought. I wanted to reiterate that I do like the Rule of Two with the Sith. It's probably one of the best ideas to come out of the PT, I think. Watching Vader talk about "rul[ing] the galaxy as father and son," and the Emperor saying, "Take your father's place at my side," it increases the tension and treachery between both characters. I find the Siths' efforts at passing on their way of life while simultaneously backstabbing each other an interesting dichotomy.
