Trapper Keeper: Part 1 - S3-E11
Continuity mistake: After Hassleberry says "That could mean Jaden's in trouble", he lowers his hand away from his face. His hand is toward the top of his chest, but when the shot cuts, his hand is lower down. (00:00:41)
Trapper Keeper: Part 1 - S3-E11
Continuity mistake: When the students are queueing up outside the nurse's office, in the first shot of the hallway, a Ra Yellow student can be seen just outside the doorway, and behind him, an Obelisk Blue student can be seen. In the next shot, the Obelisk Blue student has been replaced with a Slifer Red student. (00:02:31)
Win Mr. Stein's Duel: Part 2 - S3-E10
Other mistake: When Elemental Hero Burstinatrix's attack points go from 1200 to 2000, the Life Point count is displayed, instead of the attack point count that is usually shown when monsters' points change. (00:11:49)
Head in the Clouds: Part 2 - S3-E8
Continuity mistake: At the end of the previous episode, the four cloud tokens that appear on Adrian's field are summoned in attack mode (as shown by the ATK on the point display). At the start of this episode, the cloud tokens are now in defence mode. (00:02:01)
Jewel of a Duel: Part 1 - S3-E2
Continuity mistake: After Jaden destroys Crystal Beats Emerald Turtle and Cobalt Eagle, the two monsters reappear as crystals on the field. When the blue crystal appears, a shadow can be seen beneath it. When the shot cuts, the shadow is a lot smaller. (00:19:48)
Jewel of a Duel: Part 2 - S3-E3
Continuity mistake: When Aster is telling everyone that Jesse was chosen by his monsters, just as Blair says "Give me a break", a Ra Yellow student can be seen sitting next to Chazz. A couple seconds later, when Aster says "You don't believe me", the student sitting next to Chazz has disappeared. (00:10:03)
Continuity mistake: When Jaden is sitting on the Duel Academy ledge, just after Syrus and Hassleberry are first shown standing on the ground, Hassleberry comments that imaginary companions are a natural part of cognitive development. At this moment, he has his elbow against the large stone behind him. When the shot cuts, the position of his arm on the stone has changed. (00:05:08)
