A Hassleberry Hounding - S2-E3
Character mistake: At the start of the episode, Jaden says that he and Syrus have to carry 14 replacement duel disks across campus, which is later revealed to be because Hassleberry beat each of the 14 students in a duel and then stole their duel disk. But during the duel later on, Hassleberry says "I'm beating you the same way I beat my last 12 rivals", instead of the 14 students that were stated earlier. (00:00:09 - 00:15:35)
Character mistake: When Jaden uses the spell card Gift of the Martyr to increase Neos' attack points to 5400, T-Bone shouts "That ain't right. Fifty-four grand?", but fifty-four grand would be 54,000 and not 5400. (00:17:52)
Character mistake: After Alexis has White Knight Queen attack Sparkman and then has Snow Fairy attack Card Trooper, Jaden tells her that Sparkman's ability activates, which allows him to draw one card. This is not correct; it is actually Card Trooper that has the ability to let him draw one card, not Sparkman. (00:06:44)
Character mistake: When Jaden has his Elemental Hero Neos and Neo-Spacian Flare Scarab fuse together, he says "Roll call, Flame Scarab, Neos, contact fusion." When he says this, he incorrectly refers to Flare Scarab as Flame Scarab. (00:17:20)
Tough Love - S2-E43
Character mistake: When Zane activates the trap card Power Wall, he explains that for every card he sends to the graveyard, Syrus loses 100 points. What he meant to say, was that for every card he sends to the graveyard, the amount of life points he loses during the attack is reduced by 100 points. Since neither Zane nor Syrus lost life points during this, what he said was obviously incorrect. (00:14:47)
Tough Love - S2-E43
Character mistake: When Zane is explaining Cyberdark Dragon's ability to Syrus, he says that for every card in his graveyard, his dragon gains 100 points, before saying "Since there are 38 dragons in my graveyard, Cyberdark Dragon gains 3800 points." However, his deck consists of monster cards, spell cards and trap cards, his statement that there are 38 dragons in his graveyard is incorrect. (00:18:00)
