Thanks for the feedback, Pan! Looking at AotC’s script, the cleanest option for a dialogue change would be when Obi-Wan is reporting to Yoda & Mace on Kamino. After saying that Sifo-Dyas requested the army 10 years ago, change his line from “I was under the impression he was killed before that” to “I was under the impression he went with Dooku.”
Speaking of the Council of Geonosis, this would likely take far more time and effort than most people have (myself included), but has anyone ever thought of creating a three-second shot of General Grievous at the table, just to ever so briefly set his RotS appearance?
