Continuity: In the breakfast scene, Nightcrawler teleports onto the chandelier to grab food. However, in previous shots we've seen of the dining room, there was no chandelier anywhere near the dining room table.

Plot hole: In the end of the episode, Wolverine is seen recuperating after surgery removes the microchip in his brain, and his head is bandaged. Performing invasive surgery on Wolverine's brain isn't possible, since that would require going through his adamantium-infused skull and no conventional material is capable of that. Only a less invasive technique (such as going through the cranial sutres or cranial foramen) would have been effective and that most likely would not have required Wolverine's head to be bandaged (especially with his rapid healing mutant ability).

Revealing: When Wanda traps Magneto in the force field thing, for one shot, Magneto is missing a sleeve on one arm, then it comes back a shot later.

Continuity: When Nightcrawler teleports into the police car, the seat belt is buckled around him. How did the seat belt buckle itself around him? The police wouldn't have buckled the seat belt for no reason.

Continuity: When Kitty goes to get a midnight snack, her hair is down. But a few shots later, her hair is up in a ponytail.
