Continuity mistake: Gambit's sleeves turn from black to pink when Bella Donna reveals to him that she double crossed the Thieves Guild. (00:13:25)
Continuity mistake: In Gambit's flashback it is shown that the chosen one from the Guild of Thieves is banished to a "darkness never-ending" for breaking the covenant of the tithe. However, the same character can be seen later in the episode fighting alongside his fellow guild members.
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.
