When Scott walks away eating the apple he's stolen, you can see him stop at the corner and throw the apple core away. In the next shot he's holding the apple again, takes one last bite out of it, and throws the core away a second time.
When Tony, Linda and Scott go out to dinner, Scott is sketching something. When Linda asks what he's drawing, he scribbles on the picture. A closeup is shown of the drawing: a steel plate penetrated by a pencil, and no scribbling.
