If you were to sum up what this season is about, what would you say? It's not entirely about the chase for Drew Thompson, since they haven't spent that much time on it. It's not about Boyd and Raylan. It's not about Boyd trying to defeat a preacher who's converting his addicts into believers.
"Foot Chase" is another episode in Season 4 that seems to have an idea of where the season is going, but falls short of organizing the tumbling ideas, plots and arcs.
