Jar Jar has already served his role in the saga. In Episode I he brought the Gungans and the Naboo together. Only together were they able to bring down the Trade Federation. In AOTC, while he served little purpose, he was given a small cameo role for continuity purposes. On top of the cameo, GL needed a fall guy to set up the beginnings of Palpatines tight grip on the Republic. He has served his purpose as far as I am concerned. It will be nice to see him one last time before the end, but he is no longer needed in the grand scheme of things. TPM: Jar Jar did something important. AotC: Jar Jar did something important. RotS: Jar Jar is seen and not heard. I ask you, which one does not belong in a 3-part story?
