Plot hole: After Wolverine tells Gambit that he only knows how to pick pockets and steal candy from babies, Gambit attempts to retaliate by kinetically charging one of the bricks Wolverine is working with in order for it to blow up in his face. Anything Gambit kinetically charges makes a high-pitched humming sound, and Wolverine possesses a superhuman sense of hearing, so he should not have been caught unaware by it. (00:06:55)
Plot hole: Towards the end of this episode, Jean Grey nearly falls to her death when a concussion blast from Cable's gun knocks her off a cliff, only for her to be saved at the last moment by Rogue. Apparently Jean Grey and the writers for the episode forgot that her telekinetic powers give her limited flight ability as well as the ability to slow falls, both of which she has demonstrated in other episodes.
Continuity mistake: When Warren Worthington's fireplace is first shown, it is depicted as being raised off the floor and surrounded by masonry on all sides, with a wooden floor in front of it. When he is telling his girlfriend that she wouldn't want to get close to him, the fire is closer to floor-level, and the masonry that was underneath the fire is now a slab on the floor. (00:02:07 - 00:02:30)
Factual error: The commercial airplane that Rogue is piggy-backing to Muir Island has no overhead storage bins. Just a shelf running the length of the cabin with luggage stacked on top, which is not something that the FAA or any other national aviation authority would permit. (00:09:20)
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.
