In season four of AMC's Breaking Bad, fast food store manager-drug kingpin Gus Fring smoothly offers a first and only piece of personal
history in response to DEA agent Hank’s probing questions: there is no record
of him in his home country of Chile because he escaped during the dictatorship
of Augusto Pinochet, whose regime kept notoriously bad records. This detail and
Gus’s (real or invented) history is never mentioned again, and by the season
finale, Gus is dead anyway. But this quick and easily dismissed reference to
Pinochet’s Chile may just have everything to do with the entire plot and
trajectory of the series—not so much in Gus’s story, however, as in Walt’s.
