Other mistake: Ka-Zar refers to Xavier by name despite only having just met him and Xavier never telling him his name. He even asked Xavier who he was only moments before. (00:09:19 - 00:10:17)
'Til Death Do Us Part: Part 1 - S2-E1
Other mistake: When Wolverine, Gambit and Beast are battling members of the Friends of Humanity, Wolverine slices through the gun of one of their members. From the angle Wolverine is standing respective to the F.O.H. member, he could not have possibly sliced through the gun without also slicing off the man's left hand. (00:12:00)
Other mistake: When Gambit is consoling Rogue just before she is taken to be tortured, he tells her that he loves her, and states that he has never said that to anyone before. But as we learned earlier in the season, Gambit was engaged in his youth to Bella Donna. Surely he told her he loved her at some point. Rogue is aware of this aspect of Gambit's past, so he would have nothing to gain by lying to her about it.
Other mistake: When Magneto is asking how the Savage Land mutates were able to infiltrate his citadel, Amphibious tells him it's because Mr. Sinister long ago found his secret passage. The room they are in leads to a balcony, and has no door sealing off the balcony. In a world of superpowered beings, some of whom can fly, it wouldn't take much effort to get into a building that isn't closed off. Finding a secret passage from the ground level would be unnecessary. (00:15:00)
'Til Death Do Us Part: Part 2 - S2-E2
Other mistake: When Mr. Sinister and the Nasty Boys are fleeing from the X-Men, their plane takes off a split-second after they have all disappeared into the treeline. (00:19:10)
'Til Death Do Us Part: Part 1 - S2-E1
Other mistake: When Morph, disguised as the reverend, is saying goodbye to Cyclops, the characters in the background never move a muscle. (00:04:10)
'Til Death Do Us Part: Part 1 - S2-E1
Other mistake: When Gambit is attempting to kiss Rogue at the wedding, the man standing over Gambit's right shoulder has no face. (00:04:03)
Other mistake: Julianne Klemm, the writer for this episode, has her first name misspelled in the opening credits as "Julaianne." (00:02:07)
Other mistake: When Gambit pushes Bella Donna down, the wedding veil that she was wearing comes to a stop in midair. (00:14:25)
Other mistake: When Wolverine is threatening Pierre, there is a continuous shot lasting roughly 8 seconds in which Bobby is telling Rogue about Bella Donna, all the while Wolverine and Pierre remain in the foreground, and neither of them so much as moves a muscle in that 8-second span. Rogue also remains motionless for a majority of the shot. (00:13:35)
Other mistake: When Bella Donna's henchman is letting Bobby go, he is shown to be walking over to Bobby empty-handed. After he unties Bobby, the tithe box has magically appeared in his hands. (00:11:10)
Other mistake: When Gambit is wiping sweat off his forehead, the locks of hair that he is rubbing his fist against do not move. (00:05:20)
Other mistake: When Wolverine, Rogue and Jean Grey are falling down the hole, they are all falling at the same rate, yet Wolverine lands a couple seconds after the other two. If anything, he should have landed first because he weighs more than them, especially since his bones are coated with metal, and Rogue and Jean Grey are shown to be slowing their falls by using their flight and telekinetic powers respectively. Wolverine also appears to land a couple feet in front of the hole.
Time Fugitives: Part 1 - S2-E7
Other mistake: When the Friends of Humanity member is going through pictures of the X-Men on his watch, Wolverine is shown to have blond hair.
Other mistake: When Bella Donna is saying that Gambit was wise to leave the Thieves Guild, there is a black horizontal line on Gambit's right cheek that disappears and reappears in sync with his blinking.
Other mistake: After Rogue knocks Gambit over, Gambit is in the foreground and Rogue is in the background. Despite this, the heel of Rogue's right boot appears in front of Gambit's left foot. (00:06:32)
Other mistake: When the Blob picks up the bucket of ice cream, he says "Oh boy, tutti frutti!", but the label on the bucket says "Vanilla." (00:03:50)
Other mistake: When Rogue drops the mug of coffee onto the floor, you can see that the coffee touches her boot, yet her boot does not get any stains on it. (00:04:05)
'Til Death Do Us Part: Part 2 - S2-E2
Other mistake: The show establishes that Jubilee is Chinese-American, but after she accidentally blasts Wolverine, the way she pronounces "Sorry" is the way the word is typically pronounced by Canadians (most of the show's voice cast, including the actress who voiced Jubilee, are Canadian). (00:11:00)
Other mistake: During a flashback, Rogue is shown absorbing Pyro's mutant power and then creating fire out of thin air. However, Pyro does not have the ability to create fire, he can only control it. That's why he wears a flamethrower on the back of each hand.
