Continuity mistake: When Rogue takes the unconscious Gambit into the War Room, she sets him down on the center table and stands at the edge of it. When she is showing Storm that she absorbed his powers, she reaches over to grab a coffee mug. There were no coffee mugs on the table when Rogue set him down, and they would be out of reach if they were located on another table. (00:16:57)
'Til Death Do Us Part: Part 1 - S2-E1

'Til Death Do Us Part: Part 1 - S2-E1

'Til Death Do Us Part: Part 1 - S2-E1
Continuity mistake: When Storm is talking to and walking towards Jubilee in the War Room, the TV that everyone was watching is suddenly off, and seems to have disappeared altogether, as no screen is visible. When the shot changes, the TV is back on, and the screen appears to be shorter and wider than first shown. When Xavier is leaving the room, the TV is off again, and the screen like before seems to have vanished. (00:09:16 - 00:10:02)
'Til Death Do Us Part: Part 1 - S2-E1
Audio problem: When the Friends of Humanity are approaching the mutant that looks like a werewolf, they are saying "No more mutants," and none of them are pressing their lips together to produce the "M" sounds when saying "more" and "mutants." (00:08:37)
'Til Death Do Us Part: Part 1 - S2-E1
Continuity mistake: When the Friends of Humanity are attacking the mutant, the amount of spacing between the letters on the sign that says "Burgers" decreases when the shot changes. There is also a man painting a red "M" on the door below the sign with his left hand while holding a paint bucket in his right hand, and he only paints half the letter before the shot changes. When the shot does change, the "M" is fully formed, and the brush and bucket have swapped hands. (00:08:28)
'Til Death Do Us Part: Part 1 - S2-E1
Continuity mistake: When Morph is first blasted by the Sentinels in the flashback, it leaves a small hole in the chest area of his uniform. When Mr. Sinister approaches him, the hole is now much larger, exposing his entire chest and abdomen. (00:07:47)
'Til Death Do Us Part: Part 1 - S2-E1
Continuity mistake: When President Kelly is issuing a pardon to Beast, the lapels of his suit jacket are white. A couple of shots later, they are the same peach color as the rest of the jacket. (00:05:54)
Continuity mistake: When Beast is first shown in his prison cell, the X logo on his waistband is black with a red background. When Jubilee hugs him, it is now a red x on a yellow background. (00:19:51)
Factual error: When Senator Kelly is giving his campaign speech, the U.S. flag behind him is missing one stripe and has at least two too many stars. (00:19:30)
Continuity mistake: At the beginning of Senator Kelly's campaign speech, his campaign button is predominantly white with some blue at the top and bottom. When the shot changes, the majority of the button is now blue, with only a small portion in the center being white. (00:19:20)
Factual error: When a parachuting Xavier is about to land, you can see his legs are bent at the knee to brace for landing. Since Xavier is a paraplegic, he shouldn't be able to do this. (00:19:14)
Revealing mistake: When Xavier is parachuting towards the ground, the stars in the sky are flickering on and off. (00:19:00)
Continuity mistake: When Jubilee is saying how much being a member of the X-Men means to her, one shot shows Gambit looking despondent, and the lines on his collar armor are missing. (00:10:53)
Answer: Chris Potter, the original Gambit voice actor, did indeed quit the role in the 4th season. His last episode was The Phalanx Covenant Part 1 so it seems reasonable that Fox would limit the use of the character even though it was recast. It doesn't appear that Potter left the role due to animosity, he stated in an interview that he wished to play Gambit in the first live action X-Men film.
