'Til Death Do Us Part: Part 1 - S2-E1
Stupidity: When Morph, disguised as Storm, tricks Jubilee into going to the Friends of Humanity's headquarters, he changes back to his regular form and says that's what she gets for thinking she could take his place before she even exits the room. It's amazing she didn't hear him and turn around to see his deception. (00:15:55)
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.
