Grievous in Episode II
The battle droids need some kind of central computer to control them. in the past this was done through droid control ships. in a deleted (and hopefully restored in a future release) scene from episode II, the Jedi knock out the ship but are horrified to find that the droids are still active. I think that this is because General Grievous really is the supreme droid commander and through some complicated transmission relay, functions as a control for every droid in the galaxy. Therefore he must've been involved since at least the formation of the confederacy, though it is a little strange that the confederacies number two man is not present at the episode II meeting.
he must've been on Geonosis during episode II.
Any thoughts?
