No follow-up with Shirley. Feel like we missed something?
He finally gets with the hip crowd, and Shirley. I thought she was a rich woman (maybe not)and paying Joe. Yet, there is no explanation if it was just a one-night stand, or if he revisited her only to meet with rejection,etc.
Or did Joe figure he had enough by that point and didn't even want to pursue anything anymore. Naturally, it served the plot that he took Ratzo to Florida, so staying with Shirley would not fit in, but I'm wondering what the point of them meeting was supposed to convey. It had to be more than to show us he wasn't impotent.
