When Harry opens the file cabinet drawer to show Shirley (aka Kim) the 'old accounts' the drawer is completely empty. In an earlier scene, Lucy opened the drawer above it to find the Dawson file and the file drawer was clearly labeled 'new accounts.' Harry opens the same drawer to show Kim/Shirley the 'new accounts.'
When Kim/Shirley purposely opens the file cabinet drawer so that Harry will bump his head, a metal vase atop the filing cabinet falls to the floor. Lucie notices it but does not pick it up.
Harry does not recognize his own niece even when inches from her face.
