I spent half of the episode confusing Ginsberg with Peggy's boyfriend, and not remembering when Peggy and Ginsberg got together. Eventually I figured it out. I really enjoyed Ginsberg's storyline, I hope he and Stan continue to receive more screen time. Along with Harry's transformation into something resembling villainy and Pete's struggles with emulating Don, I've been far more interested in the underlings than the major executives at SCDP this season.
As for the LSD-influenced accountant, I think another major part of his presence wasn't just to show the drug culture that Roger was tangentially apart of, but also to introduce the idea of using the social rights movements of the time to your favor with your advertisements, be it by targeting the demographic or by using fear tactics to appeal to those who oppose the movements. As they said, even if they didn't make the molotov cocktail insurance commercial, there will be advertising agencies who would gladly do that.
