Continuity mistake: A pair of scissors covered by a square of gauze bandage is next to Alfred's arm, but in the following shot the gauze is missing.
A Dark Knight: A Beautiful Darkness - S4-E13
Audio problem: Near the start, as Gordon tells the crook "how about you exercise your right to remain silent", the shot cuts and we can hear the audio from the different take which hasn't been spliced in properly. As a result the line actually is heard as "right to remain silent-silent."
A Dark Knight: Queen Takes Knight - S4-E11
Continuity mistake: When Bruce puts his emancipation papers in front of Alfred, he also sets a pen next to them. When Alfred picks up the paper, the pen is gone.
Suggested correction: The pen is still there.
Watch the scene again and point out where the pen that was next to the papers is. And Alfred never picks it up before picking up the papers.
