“Witness” is the episode Better Call Saul viewers have long been waiting for, the one in which Gustavo “Gus” Fring finally makes his debut. Gus was—or is that will be?—the primary antagonist of Breaking Bad, the series to which BCS serves as a sequel. Watching Mike Ehrmantraut and his occasional partner of convenience Jimmy McGill work their way through their relatively petty crimes toward this apex predator’s stalking ground over the course of the past two seasons has been like hearing the longest, most morbid version of “The Aristocrats” ever told.
There was every risk that the introduction of such a massive figure, a mainstay in any list of the greatest villains the medium has ever produced, would throw this relatively quiet show’s careful balance of black comedy and quiet menace out of whack. But as it happens, we needn’t have worried at all. Gus doesn’t make the kind of grand entrance that would overwhelm the show’s dual-narrative structure, in which Jimmy’s love-hate relationship with his more successful but mentally ill brother Chuck slowly drags him into criminality on one half of the ledger while Mike’s natural talent for skullduggery and bloodletting push him deeper into the underworld on the other. Smartly, the show reunites the two characters for Gus’s introduction, sending Jimmy into his restaurant for a failed reconnaissance mission at Mike’s behest. By the time we realize who he is, the Chicken Man has been milling around in the background of the shot for several seconds, sweeping up like the conscientious manager of a fast-food place he pretends to be. As Jimmy sits and looks around for a sign of the man behind Mike’s pursuers, that very man slowly, slowly, slowly draws near to him, almost brushes up against him, and passes him by. His face is always either out of focus or out of frame entirely. The effect is like you’ve gone swimming in deep water, and you’re watching a friend float around obliviously as the silver-gray shape of a shark swims right past him.
