Continuity mistake: Near the end of the episode Michael Madsen's character attempts to run over Sam with a forklift, causing the boy to fall into the water and almost drown. As the boy is falling into the water, there is a wide shot of the action. In the scene, a box is being pushed over the edge into the harbor. In the close shot following, the box is gone, as are other items nearby.
Revealing mistake: When Sam is helping Frank clean his truck, an old couple passes as they are talking. Watch the shadows on the left side of the frame right before they enter. The shadows pause for a second, and then the couple walks on screen as they are being cued by the director.
