Audio problem: 1897: Quentin challenges Barnabas by pulling a decorative sword from a wall display and pointing it at his throat. Unfortunately, the display wasn't all that well attached to the set wall. Though the camera pans away, you can hear a loud clunk as the piece falls, followed by the loud crash of shattering glass as it strikes and breaks a table lamp. You can also see the actors struggling very hard to keep straight faces as they continue with their lines.

Other: 1968: The now-vampire Angelique kneels beside Barnabas' chair to tell him he belongs to her now. When she tries to get up, her long white gown catches on something, causing her to muff her next line a bit as she gives the fabric an annoyed tug to free it.

Continuity: 1967: Barnabas selects a treasure from a jewelry chest while bad guy Jason spies on him through a window. Willie is supposed to put the chest away, but when Jason later breaks in to steal it, the chest is still sitting on the table in plain view, so Jason has to pretend not to notice it. The break-in scene is recapped the next day, only this time, the chest is no longer on the table.
