Stupidity: Dr. Greg seems to catch some of the more obvious quirks of inmates attempting to take a large vial or bottle from the cabinet. Yet he doesn't seem to notice when Lizzie grabs a bottle of pills and pockets them from the rolling cart in front of him. (00:20:15 - 00:20:45)
Revealing mistake: For a prison governor/warden, Mrs. Davidson (Erica) would presumably earn a modest upper middle class salary. Yet here she is on the phone, in the foyer of her home, wearing an elaborate house dress, surrounded by very stellar furnishings. But then she answers a knock at the door, and opens it to reveal a very ugly vertical striped wall mere feet behind her visitor. Obviously indicating that she either lives in a dim-tenant or low-scale apartment, or this scene was shot in-studio.
