By John Keegan and Henry TranSterling Cooper Draper Pryce is an advertising firm. So we know from the outset that they deal in popular consumerism. They try their hardest to make money off of what people desire. Only, the people who work at the firm aren't getting what they desire the most. The most obvious example of this mindset has been Pete throughout the season, but he has a small role in this episode. No, the unfulfilled desire comes from other places and other characters, including one, Paul Kinsey, who hasn't been seen in two seasons. This causes plenty of frustration, which is only beginning to bubble to the surface in some cases while bursting at the seams in others. It has been a really dark season so far (even by "Mad Men" standards) and I don't think this is the last we're going to see of it.
