In the opening sequence, when the troopers lead away Senator Avi Singh, his protocol droid GS-8 hurries away in the other direction. But moments later, as Captain Bragg gives order via her Comlink, the droid is seen standing behind her.
Before Captain Bragg tortures Senator Avi Singh, he tells her her "draconian tactics won't work..." The term draconian comes from Draco, a legislator from Ancient Greece, someone no one in this galaxy would know about.
