Continuity mistake: When Jaden is asking Jesse if he saw where the guy with the pompadour went, in the wide shot, Alexis can be seen standing 90° perpendicular on his right. When the shot cuts, Alexis is standing 90° perpendicular, but a few meters ahead of him. (00:11:27)
Continuity mistake: After Jaden accepts Marcel's offer to duel, a couple of students berate him. Jaden then says "Come on, guys, we can win. After all, we can't afford to lose", with his right hand raised. In the next shot, his right hand is lowered. (00:13:59)
Other mistake: After Jesse summons Sapphire Pegasus, he says he can now summon another Crystal Beast in his spell and trap card zone. In a close-up of his hand, there are four cards, and we can see Ruby Carbuncle is on the right-hand side. Jesse then reaches for the trap card next to Ruby Carbuncle, but then Jesse summons Ruby Carbuncle in his spell and trap zone despite not picking it. (00:15:10)
Plot hole: When Marcel is standing in an abandoned area, he hears Bonaparte shout his name. Adrian is then seen standing a short distance behind Marcel, and then hides once he sees Bonaparte approaching. There's no way Bonaparte didn't see Adrian. Even if Adrian hid, Bonaparte was already close enough to see Marcel, so he should have seen Adrian as well, or at the very least, seen him on his way to find Marcel. (00:17:10)
Return of the Sacred Beasts - S3-E22
Continuity mistake: At the end of the previous episode, just after Marcel opened the hole in the ground, an overview shot showed the Duel Ghouls that were approaching, in a vertically aligned queue, with no more than two beside one another. At the start of the episode, the queue appears to be more horizontally aligned, with the Ghouls positioned side-by-side. (00:01:57)
Return of the Sacred Beasts - S3-E22
Continuity mistake: At the end of the previous episode, Syrus and Miss Fontaine were shown among the Duel Ghouls who were approaching Jaden, Blair and Bonaparte. But in this episode, they cannot be seen in the group of the Duel Ghouls when Blair realises they are still approaching them. (00:02:42)
Return of the Sacred Beasts - S3-E22
Continuity mistake: When Jaden jumps into the underground chasm, Blair and Bonaparte turn around and see that the Duel Ghouls are still approaching them. At this moment, Bonaparte is behind Blair. When Pharaoh leaps up at the Duel Ghouls, Bonaparte is ahead of Blair. (00:03:08)
Return of the Sacred Beasts - S3-E22
Plot hole: When Marcel is running through the underground chasm, Chazz emerges from a small passageway that Marcel passes. The last time Chazz was seen, he was one of the Duel Ghouls approaching Jaden at the end of the previous episode. Marcel only got to where he was so quickly because jumped and ran through a chasm he opened, so there's no way Chazz could have gotten down there through a hidden passageway before him. (00:03:35)
Return of the Sacred Beasts - S3-E22
Continuity mistake: When Bastion inserts the crossover cable into his student notebook, in the close-up shot we can see the cable is held in his right hand. When the shot cuts, the cable is out of his hand. (00:13:23)
Return of the Sacred Beasts - S3-E22
Continuity mistake: After Professor Eisenstein explains they need to go to the tennis court for the inter-dimensional duel to take place, it cuts to Bastion saying, "There's no time to waste, let's move." At this moment, Hassleberry is behind Bastion to his right. But in the next shot, Hassleberry is directly behind Bastion. (00:16:30)
Return of the Sacred Beasts - S3-E22
Continuity mistake: When Neos and Grand Mole jump into the air to fuse together, Jaden's right fist is raised at a slanted angle. In the next shot, his fist is suddenly at an upright angle. (00:17:52)
Return of the Sacred Beasts - S3-E22
Continuity mistake: When Marcel finds the room where the Sacred Beasts are kept, there are two cables leading out of the doorway and into the box where the cards are hidden inside. When Marcel first walks into the room, the cables are positioned to the left-hand side of the doorway, but when Adrian walks into the room seconds later, the cables are positioned to the right-hand side of the doorway. (00:19:20)
Breaking of the Sacred Seal - S3-E23
Continuity mistake: When Echo is warning Pegasus not to move closer, in an overview shot, there are two aides on his left. One is a few meters next to him, and the other is a few more meters ahead of the first aid. Just under a minute later, when Pegasus says "Okay, I was kind of with you until that last bit", both aides to the left of Pegasus are side-by-side. (00:10:55 - 00:11:50)
Breaking of the Sacred Seal - S3-E23
Character mistake: When Marcel activates his two face-down cards, he says "I'll start by revealing my two face-down cards which both happen to be Break the Seal spell cards", but they are trap cards as they are pink and spell cards are green. (00:15:10)
Breaking of the Sacred Seal - S3-E23
Continuity mistake: After Adrian realises Marcel was holding four of the five Exodia cards in his hand, Adrian comments "If you had drawn one more card, you would have completed Exodia" while holding onto Marcel's arm. In this shot, there is a small gap in between his little finger and his right finger. When the shot cuts to Marcel, the gap in between his fingers is closed. (00:16:52)
Breaking of the Sacred Seal - S3-E23
Continuity mistake: When they have finished setting up the inter-dimensional duelling system, there is an overview shot that passes over the main characters. In this shot, Pharaoh can be seen sitting on a console, directly in front of Blair. When the shot cuts to Blair and Pharaoh, Pharaoh is now sitting in front of Blair, to her right. (00:19:30)
Continuity mistake: When Pegasus is being fitted with the cyber-design interface and virtual reality headset, there are two cables attached to the left-hand side of the headset that are not attached to the duel disk on his arm. A couple seconds later, the two cables on the left-hand side are suddenly attached to the duel disk. Two cables on the right-hand side of the headset attached to the glove on his right hand also appear from nowhere. (00:00:13)
Continuity mistake: When Crowler walks into the Chancellor's office to see Jaden there, in the first shot of him, his head is upright. When it cuts to a closer shot of him, his head is suddenly shifted to the left. (00:01:09)
Revealing mistake: When Pegasus has finished designing the Rainbow Dragon card, Chancellor Shepherd and a group of background extras start applauding. There is one extra wearing a lab coat standing behind Shepherd with black hair, who is reused in the same shot when it pans over to another group of extras on the opposite side of the site. (00:03:20)
Continuity mistake: When the Duel Ghouls break open the doors to the tennis court and Hassleberry and Axel walk back inside, in the crowd of Ghouls, the first row appears to be an Obelisk Blue student, a Ra Yellow student and a Slifer Red student. In the next shot, a Ra Yellow is now seen where the Obelisk student was standing and an Obelisk Blue student is where the Slifer Red student was standing. (00:17:02)
