'Til Death Do Us Part: Part 1 - S2-E1
Continuity mistake: Professor X's wedding tuxedo suddenly changes into his usual green suit when Beast is giving an update about President Kelly. (00:05:50)
'Til Death Do Us Part: Part 1 - S2-E1
Continuity mistake: The ribbon on the wedding present that Beast is carrying disappears when Jean's bouquet lands on it. (00:05:30)
'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)
'Til Death Do Us Part: Part 2 - S2-E2
Continuity mistake: When Morph collapses after finally remembering how he came into Mr. Sinister's service, his boots which are normally yellow are colored blue. (00:15:00)
'Til Death Do Us Part: Part 2 - S2-E2
Continuity mistake: When Magneto and Professor X meet in Antarctica, the white stripes on Magneto's right glove are red in one shot. (00:20:10 - 00:20:45)
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.
Factual error: At the end of the episode when Carol Danvers is shown comatose, there is an EEG machine next to her bed. This machine monitors brain activity and uses electrodes on the patient's head in doing so. She has no electrodes placed on her head, and the machine isn't detecting activity in her brain. (00:20:37)
Other mistake: After Magneto says "Trust me, you'd rather not know," a hole appears in his pants around his right hamstring and then quickly disappears. (00:02:50)
Other mistake: When Xavier asks Magneto how much further they have to reach the top of the cliff, Magneto tells him he would rather not know, suggesting they still have a long way to go. However, in the wideshot of the sky-riders flying in to attack the two, you can see Magneto is about three times the length of his own body from the top, and according to the book "X-Men: The Art and Making of the Animated Series," Magneto is 6 feet tall. This means he is only about 20 feet, give or take, from the top, which isn't all that far in terms of climbing a cliff. (00:02:44)
Character mistake: When wondering how close they are to the top of the cliff, Xavier asks Magneto "How much further?" The word "further" is used for non-measurable or figurative advancement. He should have asked how much farther, as that refers to actual distance between objects. An educated man like Xavier would certainly know the difference between the two. (00:02:44)
Suggested correction: While "farther" is used for physical distance, further can be too, especially in British English. Farther also tends to be used for a measured physical distance, so if the actual distance isn't known, further can be used. What Charles said is grammatically correct.
Mojovision - S2-E11
Revealing mistake: When the X-Men are being returned to the electronics store, there is a noticeable jump-cut (odd for a cartoon) just before Wolverine materializes. (00:18:40)
Mojovision - S2-E11
Revealing mistake: When the Gladiator robot shoots an optic blast at Wolverine, you can see the hole in the chest area of Wolverine's uniform is already there before the blast hits him. (00:16:24)
Mojovision - S2-E11
Revealing mistake: When Mojo's studio audience is cheering after he says "I give it two flippers up," you can tell by each character's celebratory movements that it is just a reverse of the shot where the audience was first shown earlier in the episode. (00:07:50 - 00:15:23)
Mojovision - S2-E11
Other mistake: When Jean is trying to dodge Spiral's teleporting blast, she ends up tripping on a power cord running across the floor. An electronics store wouldn't have a power cord running across its floor for this very reason. They would be begging for a lawsuit if they did. Her foot is also closer to the wall in the first shot than in the second shot. (00:07:30)
Character mistake: When Carly expresses her relief to Beast that he is fine after he was attacked by the anti-mutant group, he incredulously asks her how she knew he was a mutant. Aside from the fact that the Friends of Humanity were openly calling him a mutant in her presence when they accosted him, Carly was shown touching Beast's hand earlier in the episode. Despite being blind, she would also know that Beast's fur-covered hands would be quite different from the hands of regular people she might have touched. Given these facts, Beast should not have been surprised that Carly knew he was a mutant. (00:03:25 - 00:08:40)
Mojovision - S2-E11
Character mistake: The label on the bottle that Major Domo gives Mojo reads "Mojos aniacid," when it should read "Mojo's antacid." (00:03:20)
Other mistake: When Jean is bringing a tray of food to Beast, the liquid in the glass is not oscillating. (00:09:38)
Factual error: Whenever the comatose Carol Danvers is shown in her hospital bed, she is wearing a pink turtleneck. A coma patient wouldn't be dressed in their own personal clothing. It could obstruct doctors and nurses in an emergency. She would be wearing a hospital gown. (00:09:19 - 00:20:45)
Time Fugitives: Part 1 - S2-E7
Continuity mistake: When the Blackbird is shown recording the hearing, you can see Graydon Creed standing in front of the podium. When the shot changes to the hearing in the chambers, Creed is suddenly standing behind the podium. (00:14:32)
