After watching “XXIII,” I am left thinking of the words of Bertrand Russell, a famous British philosopher, logician, mathematician, historian, social critic, and political activist. “War does not determine who is right, only who is left.” Since the beginning of the season, the subject of war has been a constant theme. As Black Sails reaches the halfway mark of season three, “XXIII” represents a pivotal moment where, once again, political alliances shift, loyalties are tested, and the lives of various characters are on the line.
