When MS gets into the van, she notes that Milkman has "a few small medicine bottles, holding many of those shiny black pills with the white dots in the middle of them, one of which was still in my handbag". This is the pill that she was given in the nightclub by the other women. Are we supposed to know what this pill is? Are we supposed to infer that he was intentionally the source or even that he is a dealer?
