Night of the Sentinels: Part 1 - S1-E1
Continuity mistake: When Gambit and Wolverine are sparring in the Danger Room, at one point Gambit dives onto a piston and then rolls off moments before it smashes him into another piston, with a piece of the bottom right of his trenchcoat being torn off in the process. When Jubilee is explaining to everyone that she was trying to help Gambit, his trenchcoat is now untorn. (00:11:07 - 00:11:43)
