Neogenic Nightmare Chapter 4: The Mutant Agenda - S2-E4
Continuity mistake: When Spider-Man is battling the X-Men, he shoots webs at all of them, which they remove.

Continuity mistake: A whimpering housemaid rushes down the stairway, frightened by an intruder on the second floor. Doctor Watson gallantly charges upstairs to investigate, plunging his left hand into the right side of his jacket to retrieve his trusty Webley revolver as he advances on the camera. However, the shot immediately cuts to Watson withdrawing the revolver with his right hand from the left side of his jacket. (00:29:55)
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)
Continuity mistake: In Season 2, Episode 19 ("Checkmate"): Detectives Torres and Moreno respond to a radio call reporting gunfire at 300 East 85th Street, which they acknowledge. We then see the suspect exit the building and escape in a car, and the detectives run unto the same building a few seconds later. The building number however is 237, not 300. (00:33:35)
