Howard Hamlin, the other human quarry in this two-pronged tale, has called out his pursuer and summoned him to a boxing ring, in the apparent hope that a few rounds with gloves on will put an end to their feud. As Jimmy later nurses his wounds with Kim, he is baffled as to why he took the bait. Your Faithful Recapper is confounded by the fisticuffs themselves. A boxing match? It seems a goofy contrivance even in the context of Jimmy and Kim’s credulity-strangling plot to frame Howard as a drug addict.

Thankfully, Howard has more in mind than resolving his differences with Jimmy using the Marquess of Queensberry rules. He’s hired a private detective to follow Jimmy. This is good news for anyone who wanted this strand of the show to acquire more intrigue.

That said, Jimmy and Kim seem so utterly unfazed that Howard has discovered their plot that we have to assume it was part of their plan. (Howard suggests as much when he says Jimmy failed to hide his tracks and wanted to get caught.) Perhaps tipping off Howard, compelling him to hire a pro to tail Jimmy, was in the blueprint. Certainly, Kim and Jimmy never speak about tweaking their scheme. On the contrary, Kim implies that everything is on track.

“Because you know,” she says, when Jimmy wonders aloud about why he indulged Howard and strapped on those gloves. “You know what’s coming next.”

Very mysterious.

There is a parallel worth noting between Gus and Kim. Neither can sleep and for the same reason. They think Lalo is about to appear. So Gus has hired bodyguards and a surveillance team. Kim has wedged a chair against her apartment door.

The Most Entertaining Appearance of the Week award goes to Francesca Liddy (Tina Parker), who turns up at Saul Goodman’s grim, unfurnished office and can hardly process what she’s seeing. Jimmy is using a new name and has pivoted away from elder law to serve unseemly clients who have lined up outside the door like it’s Wal-Mart on Black Friday. She agrees to join this new enterprise — a decision she will rue by the end of “Breaking Bad” — under two conditions. A raise, plus “I get a say in the decorating.”

Francesca, if you’re responsible for the U.S. Constitution theme of Saul’s office and those Roman columns, we need to talk.

Mrs. Ryman is a Toto fan!

It’s not just existential dread that is driving Gus a little nuts. Even before Lalo showed up, construction of the superlab was behind schedule. The delays are expensive, of course, and risky as well, given that Gus’s secret German partner and equipment supplier, Peter Schuler, was on the verge of a nervous breakdown when we last saw him. The delays also add plausibility to a key plot point of “Breaking Bad.” Walter White exploited Gus’s fear of falling behind on the lab’s meth production schedule to save his own life. We have a better sense than ever of why that ploy worked.

And our question of the week for the comments section: What do Jimmy and Kim have in store for the man who is going to mediate the Sandpiper Crossing lawsuit? Kim has wheedled the name of the gent from an unsuspecting, somewhat fawning former associate at Schweikart & Cokely. Jimmy and Kim then get a look at the man in a copy of a bar journal and take note of his handlebar mustache.

“That’s a lot less face to worry about,” Jimmy says.

Looming plot twist alert! This is arguably the most baffling line of the season so far and clearly an important one.

What does it mean?
