Mrs. March apparently stabs Victor in the back with a downward stroke of her knife. Victor is immediately seen with a bleeding slash wound across the front of his neck. Victor is then seen on the floor in closeup, but his neck is completely unharmed. The view switches to a further viewpoint, and the neck wound has returned.
