The second episode of Reacher’s sophomore season, “Atlantic City,” picks up right where the first ended, with Reacher and allies Neagly and O’Donnell learning that a second member of their old unit, Tony Swan, has likely been murdered. Reacher knows its audience - dads - well enough to serve them exposition with a fistful of violence. Mary Poppins knew her audience - children - well enough to serve them a spoonful of sugar with their medicine.
