Norton’s arrival isn’t a great sign—John and Lorraine have both stated how “disturbed” and even dangerous Norton is, Norton himself has threatened to intimidate or steal from Mr. Pignati, and now he’s actively assessing Mr. Pignati’s house to determine if there’s anything worth stealing. In short, Norton’s arrival all but guarantees that this party won’t end well. This scene also paints Lorraine in a negative light. Though she, unlike John, seems to recognize the difference between right and wrong, responsible and irresponsible, she doesn’t always act on it. Here, she dresses up in Conchetta’s old clothing even though she knows it’s irresponsible and could result in someone damaging the clothing.
