“Breaking Bad” did a remarkable job of highlighting Hank’s savvy as a D.E.A. agent, while keeping the main suspect, Walter White, right under his nose. And as he negotiates with Saul and Domingo, we see his formidable side, even as he gets snowed. He pegs Saul’s act for as a farce (“I feel like my chain is being pulled, and not in a good way,” he says), but for perfectly understandable reasons, he has no idea that he’s about to do the bidding of a drug kingpin.

That kingpin is Lalo, who is getting played, too. By Nacho, who reports to Gus that his “dead drops” are now under federal surveillance. This makes Gus very unhappy.

Can we pause for a moment to consider Nacho’s plight? First, he appears to be living with a nutter. Specifically, a woman who is, for mysterious reasons, compelled to solve puzzles — the real kind, like a jigsaw, and the self-created kind, like how to clean a remote control.

But an unhinged roommate is the least of Nacho’s worries. He wants nothing more than to run for his life, the end of which he can clearly foresee, and to encourage his father, who is the quintessence of integrity, to run as well. In a poignant scene, Nacho the Elder (Juan Carlos Cantu) says he won’t retire or flee, even if his son secretly tries to buy him out of his upholstery store for an extravagant sum.

Poor Nacho. Who on this show is more miserable?

Maybe Mike, who is underemployed and idling alone in a bar, trying to drink away his anguish. These feelings must now include remorse for the trauma he inflicted on his granddaughter when he yelled at her in the previous episode. He’s in a flinty mood, and for reasons as yet unknown, he’s triggered by a photograph of the Sydney Opera House.

What did Australia do to you, Mike? We’re here to help.

The episode ends with Kim and Jimmy, tossing beer bottles off their balcony, which explode in the parking lot below. I took this as a howl at the sense of “in” that they would dearly like to escape. And yet this is probably as “out” as they’ll be. Certainly, Jimmy is about to get in way over his head.
