The Unstoppable Juggernaut - S1-E8
Plot hole: After Wolverine deduces that Colossus wasn't the person who destroyed the X-mansion and Colossus walks away, Jubilee gets a phone call from Rogue literally less than 30 seconds later informing them that the bank was being robbed by somebody big who is later revealed to be the Juggernaut. Wolverine (now wearing a different set of clothes) and Jubilee are then shown arriving at the bank in Wolverine's jeep just in time to see Colossus being arrested for the crime while claiming he was only trying to open an account and stop the robber. If the robbery was being committed while Colossus was fighting Wolverine, then the police and bank employees would have known Colossus was not the perpetrator, not to mention the bank would have been closed off to the public, effectively preventing Colossus from going in to open an account in the first place. The only way Colossus could have feasibly been implicated would be if he was at the bank the same time that Rogue called Jubilee, which he obviously could not have reached the bank in that amount of time since Wolverine had to drive there.

Continuity mistake: Gambit is the central character in the previous episode "Slave Island", and is on the Blackbird with the rest of the team when they arrive at the destroyed X-Mansion. However, the very next episode begins where "Slave Island" left off, and Gambit is conspicuously missing from the episode.
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.
