A Dark Knight: Queen Takes Knight - S4-E11
Continuity mistake: When Alfred and Bruce start to fight, Bruce is pushed into the desk - the magnifying glass tips over and the large diamond object falls off. But in the next shot, they're back up. They're gone in other shots.
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.
