Continuity mistake: When Obi-Wan and Mace retrieve the stolen holocron at Black Stall Station, the device is shown as completely closed and back in a cube configuration. This is despite the fact that the previous episodes of the arc established that Jedi holocrons can only be opened by Jedi, and it was last seen partially opened after Bane inserted the data crystal, with no contact with any Jedi between Bane's escape and the arrival at his hideout. (00:15:08)
Continuity mistake: The canopies of Anakin and Mace's starfighters appear different than they did in the previous episode, now possessing an opaque rim around the outside.
Death Trap - S2-E20
Continuity mistake: When Commander Ponds orders some other clone troopers to evacuate because he's staying onboard with the Admiral, his kama (kilt) is missing, and his blaster pistols are missing from his holsters. (00:16:46)
Death Trap - S2-E20
Continuity mistake: When the alarm goes off, Sergeant Crasher tells his cadets that there's been an explosion and that they'll show the crew how the Clone Youth Brigade does things. As he's saying this, the camera cuts from him to a closeup of Hotshot before back to Crasher, who is walking through the same group of cadets in the exact same way in both shots. (00:10:36)
Continuity mistake: When Satine is falsely identified as a suspect in a shooting, she pulls her hand with her holdout pistol under her cloak, but when two police droids approach, her hand is back out again. (00:11:23)
Continuity mistake: When Anakin is facing down one of the assassin droids, after it throws Redeye's body at him, he and the droid are suddenly in a different part of the cargo hold, with fewer crates around them. (00:09:04)
Character mistake: After Anakin says to use the walkers (AT-TEs) as boarding vessels, Rex calls the first one an AT-AT (a vehicle that does not even exist at this point in-universe) while ordering a battalion of clones into it. (00:04:10)
Other mistake: Commander Jet does not hold the rank of "Captain", but he's addressed as such, just as many times as he's called by his proper rank.
Plot hole: Cato doesn't even know who Ord (the person she is impersonating) is, and yet she manages to perfectly imitate his voice and manner. She wouldn't have transformed her own internal organs, since she probably would have ruptured them.
Suggested correction: Quite apart from anything else, Cato is a member of a shapeshifting species, so why wouldn't she be able to perfectly take the form of another species? And her internal organs have nothing to do with the plot of this episode.
