"Narcos" season three, episode one, "The Kingpin Strategy," begins with Agent Javier Pena, a Drug Enforcement Administration agent who's been through this all before, in an intimate conversation with his father. The older man pleads with his son not to put his life on the line in the name of the drug war again, knowing that he's already made his decision. "So, Cali . . ." his father says, begrudgingly accepting his son's choice. The younger Pena nods his agreement,."Cali," he says in a grave tone as the screen quickly fades to black.
