Neither of them knows it, but Gus Fring and Jimmy share the same problem: Lalo Salamanca.
"Black and Blue" opens with Jimmy and Kim in bed; Kim, unable to sleep, heads out to the couch but not before grabbing a chair and placing it against the front door. After all, when a murderous cartel member is on the loose, a little extra security never hurts, right?
Jimmy walks out into the living room to check on her, wanting to see if everything is alright, and he notices the chair, saying, "I was hoping it was just me."
After finding out from Mike that Lalo was still alive last week, Kim decides not to tell Jimmy. There is no immediate danger, so it's probably better not to burden him with the knowledge. Jimmy has enough problems right now; there's no need to add another to his plate.
"The nuns in Cicero would send me to hell for saying it, but I'm glad he's dead," Jimmy says to Kim. If only you knew Jimmy if only you knew.
Meanwhile, it was only a matter of time before Howard eventually wised up to Jimmy and Kim's schemes, and it seems he's finally had enough. As he finishes giving a speech reassuring the senior citizens of Sandpiper that they are putting all the effort they can into their case, Cliff Main confronts Howard about his "drug" problem.
Cliff runs through everything he believes Howard has done—the empty baggy at the country club, the clients who allude to his alleged problem, and then Wendy, the sex worker, being pushed out of his car.
Howard agrees to fix his problem, not the drug one that Cliff thinks he has but, as said before, his Jimmy McGill problem. How does he hope to solve this? Well, he plans to fight him—legally, of course.
Jimmy is then lured to a boxing gym by Howard. He makes it seem like he is a prospective client and then goads Jimmy into climbing into the ring with him. At first, Jimmy refuses, but, as he's been known to do, he eventually relents because he can't help himself.
When they get in the ring, they both land some punches. It's certainly not the most athletic boxing match ever put to screen, as this is two older gentlemen attempting to take out their frustrations on one another. Howard eventually gets the better of Jimmy, knocking him to the mat with a final punch to the face.
After the showdown of the century, Howard meets with a private investigator and hires him to spy on Saul and track his every move.
Clearly, Howard has had enough of Jimmy's games.
We cut to Jimmy arriving back at the apartment and using Kim's makeup to cover up his black eyes. Jimmy seems to be upset with himself for letting his desire to punch Howard in the face get the better of him, but as Kim reminds him, "you know what's coming next."
An ominous sign of things to come, no doubt.
