Revealing mistake: When Zaladane is helping Sauron escape, she uses her staff to reveal a hidden stairway in the floor. As Sauron descends the steps, the opening fades back into resembling the floor to suggest it is being hidden again, but Sauron fades away as well. It should be that Sauron walks out of view, and then the opening fades back into the floor. (00:02:56)
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.
