When Violet shows up at the cemetery she talks for a few seconds with the hemophage that has dreadlocks. At one point, before they fight, his mouth is moving as if to say something but there is no dialog heard at this point.
When Violet gives Six her credit card so that he may buy something to eat, he is wearing a pendent around his neck and his smock is without the three black patches that Violet removed shortly after rescuing Six. When Nerva pulls Six up the manhole, Six is not wearing the pendent and the three patches are missing from his smock. However, as Six struggles with Nerva outside the gate to the cemetery, the patches are visible and the pendent is missing. When we next see Six hanging over the well, the pendent is around his neck again and the patches are no longer on his smock.
When Violet and Six are in the car facing Draxus, the driver's door is open. When she reverses into the gang of attacking ninjas, the bird's-eye shot shows the car doors all closed. When we cut back to the pair in the car, the driver's door is open.
When the second lot of guards in black glass uniform enter the room, after it is identified that Violet is a mite, Violet begins to fight with them, however the same guard falls to the floor three times in different shots. Then when Violet defeats the guards wearing black glass uniforms, she drops both parts of the gun she previously took apart. In the first shot as she drops them, the part dropped to the viewers left of the screen lies perfectly flat on the ground. But in the next shot as Violet walks away and picks up the white case, that part of the gun is now sticking up off the ground, and is partially lying on a guard, and has now changed position.
Nearing the end of the film, Violet infiltrates the complex and makes her way into a white room with tons of men in white suits. She starts fighting them and when a couple of guys come at her, she moves quickly and one guy stabs the other in the chest/gut. Now she goes to elbow one of the guys in the face, watch his helmet, it comes flying off, revealing his head and hair. Then the camera quickly changes to another angle, the helmet is perfect on straight.
When the genuine XPD-154 courier arrives on her motorbike, the bike changes where it is parked between shots, just as she pulls up. It is clear to see in relation to the slabs on the floor and the cracks in between them.
When Vicecardinum Ferdinand Daxus pours coffee while talking to Nerva and the other hemophages, the cup is not filled to the brim after he stops pouring coffee in it. In the next shot, it is filled to the brim with coffee.
After Violet leaves Six to be captured by soldiers, she walks away pushing people who all seem to walk the opposite way. Then she changes her mind, kneels and turns back but again she has to push people aside as everyone is now walking the other way around.
In the cemetery, Nerva tells Violet "gunfire will attract the human security teams" convincing her to drop her pistols. Moments before, one of the hemophage henchmen fired several rounds at Violet on the street outside, with no security response.
Violet says she is leaving Garth's lab so that she doesn't get him into trouble because of Six's tracking device. However, Nerva has just told her that the tracking device is blocked when they are in the lab, so really this would be the best place for them to stay and could not put Garth in danger.
When Violet is on the motorcycle on the roof and is about to speed towards and jump through the helicopter, she spins the back tire and then we see her pop the clutch and take off. If she was holding in the clutch, the back tire would not be spinning.
When Violet enters the library with the lone guard standing there, the shots alternate between a close-up of her face and her looking around the room. The bangs in her hair switch from left to right indicating the shot got flipped during editing.
As Daxus is preparing to cut up the frozen Six, he is interrupted by an assistant who says, "It's HER." Daxus says, "She's dead", and the assistant shows Daxus a view screen of various henchmen getting blown away while pieces of paper fall all around them. This is taken directly from the Library fight scene, which hadn't happened yet.
