Neogenic Nightmare Chapter 5: Mutants Revenge - S2-E5
Continuity mistake: After Wolverine is knocked unconscious by the voltage of the cage that Beast is trapped in, Beast is able to keep Wolverine from falling into the vat of chemicals below the cage by gripping the fabric of Wolverine's costume. Once the fabric tears away, Beast is able to grab Wolverine by the hand. Once he loses grip, Wolverine is able to grab onto the cage itself. When Genevieve starts shooting the laser gun at the Hobgoblin, Beast is again shown to be holding Wolverine by the fabric of his costume. (00:08:30 - 00:12:05)

Continuity mistake: When Gersham runs from the police in the first scene, his vehicle crashes on a rooftop and hits a wall, bouncing off it, turning and stopping parallel to it.

Continuity mistake: To beat the traffic, Coop skateboards inside a construction pipe. The pipe is on the back of a truck, so it's not exactly very long, and gets picked up by a crane arm mounted on the truckbed itself. However, Coop takes ages to come out of the pipe, and in the shot from inside the pipe it looks as if is dozens of meters above the street level, which isn't. (00:08:00)
