During the first couple of scenes in the courtroom, Monique (the robot actress from All My Circuits) is clearly seated behind the Donbot's family. However, when the jury is shown on screen, she is also seated on the jury bench. She remains on the jury through the whole trial, but by the end of the scene, she disappears from her original seat behind the Donbot's family.
Francis's clamps had been cut off by Zoidberg. Shortly after Billy West is shot, we see a group shot where the clamps are re-attached but he is carrying them unattached just a few seconds later.
During the courtroom scene there's an American flag behind the judge that looks like the U.S.A. flag of today. Yet in all other shows whenever a flag is shown it's always the same 13 red/white stripes and the planet Earth replacing the field of stars.
