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)
