Kim sees Jimmy off as he travels by bus to Huell's hometown of Coushatta, Louisiana. Throughout the journey, Jimmy writes on postcards with different pens and in different styles of handwriting. He also recruits other riders into writing their own messages, paying them a few dollars for each letter. When he arrives in Coushatta, Jimmy gets off the bus and steps into the local post office. After dispensing with his enveloped messages, Jimmy waits out front for the bus going back home.
At El Michoacano, Nacho performs Hector's former role of observing cash collections. Krazy-8 counts money from a bling-wearing drug dealer, who has come up short. Krazy-8 initially allows the dealer to leave, but Nacho summons the dealer over to his table. Nacho tears off one of the dealer's earrings and warns him that, "What you owe, you owe with interest." After the dealer leaves, Krazy-8 turns around to affirm Nacho's action, but Nacho asks why he didn't do it himself. Krazy-8 acknowledges Nacho's hint, and right away another dealer enters the diner, while Nacho watches calmly.
After dark, Nacho drives a muscle car to an upscale house, where two young women are inside watching TV. Without a word, Nacho gives them small bags of crack and retreats to his bedroom. There, he stashes his drug money in a safe in his closet. As he does so, Nacho looks at fake Manitoba ID cards for himself and his father, showing that he has an exit strategy.
Mike and Werner take their workers to a local strip club, where they -- particularly Kai -- are entertained by the dancers. Observing Werner sitting alone, Mike takes him to a more traditional bar for a drink. Werner tells Mike that his father was also an engineer, who devoted ten years of his life to building the Sydney Opera House. When a third patron asks for hefeweizen, Werner politely corrects his pronunciation and pays for the patron's drink. Werner states that he misses his wife and asks Mike what his father was like, leading the two men to reflect on their families and making a toast to home. Nick shows up to summon Mike, leaving Werner behind at the bar.
Outside the strip club, Mike finds Nick and Arthur confronting a belligerent Kai, who has been thrown out for making unwanted advances towards one of the dancers. The owner threatens to call the police, but Mike bribes him in exchange for allowing Kai to return home and sleep it off. Kai reacts angrily, but stands down when Mike challenges him. Mike returns to the bar to find Werner socializing with the patron from earlier, drunkenly divulging details about the secret excavation beneath Lavanderia Brillante. Concerned, Mike collects Werner and drives away.
At her apartment, Kim is reviewing Huell's assault case when Jimmy tells her that he is going to the Day Spa and Nail to "set things up." There, Mrs. Nguyen finds Jimmy in his backroom office writing on stickers that he puts on the backs of drop phones on his desk. Assuming that Kim is Jimmy's wife and that she's thrown him out, Mrs. Nguyen pours him a glass of alcohol and urges him to take her out to a nice restaurant to make up with her. Jimmy dejectedly replies that he thinks they might be "past that." Mrs. Nguyen lets Jimmy keep the bottle as she leaves.
The next day, Kim arrives at the courthouse with a team of lawyers to meet with ADA Ericsen. Kim seeks to have Huell's charge reduced to simple battery and have his sentence reduced to several months' probation with time served. When Ericsen refuses, Kim's associates files several motions to collect evidence corroborating Huell's version of events, signaling that they are willing to begin civil rights litigation on Huell's behalf. Speaking in private with Kim, Ericsen states that she is unimpressed with Kim's "shock and awe" tactics and insists Huell is still going to prison.
Mike comes to Gus's warehouse and confronts Werner with a diagram he drew for the bar patron on the back of a coaster. Werner initially claims that he did not blab about the excavation, but eventually admits that he did so after drinking too much beer. Mike warns Werner to consider how Gus, who has gone to great lengths to keep the excavation secret, might react to his precautions being ignored. Realizing what he is saying, Werner apologizes and gives his word that nothing like this will ever happen again.
Meanwhile, Kim and Ericsen visit Judge Munsinger's chambers, where a deluge of letters -- the letters Jimmy wrote during his cross-country bus trip -- have arrived on the judge's desk demanding Huell's release. Kim denies playing any role in the letter-writing campaign. Munsinger, exasperated by the volume of the letters and the prospect of a threatened contingent of "yahoos" from Coushatta coming to pack his court, demands that the two women resolve the case without causing a circus.
Ericsen returns to the DA's office and orders her subordinates to comb Huell's file. Reading the letters, she phones one of the purported authors, who claims to know Huell from her church in Coushatta. One of the subordinates finds a website for the church, which is raising funds for Huell and shows lighthearted photos of him. It is revealed that the person Ericsen is talking to is actually the Drama Girl, speaking to her on a drop phone; she, Jimmy, and the other two members of Joey's film crew are in Jimmy's backroom office, where a bunch of drop phones have been set up to help make the letters look real. When Ericsen calls the "church," Jimmy takes the call on another drop phone, pretends to be Huell's pastor, and spins a yarn about Huell rescuing elderly congregants from a church fire. When Ericsen, finally fooled by the ruse, stops making calls on the other drop phones, Jimmy gives the film crew instructions on how to answer them as he leaves the office. Jimmy arrives at the courthouse and sees Kim negotiating with Ericsen in a courtroom. Outside, Jimmy follows her into a stairwell, where she passionately kisses him.
The following morning, Jimmy and Kim are in bed together, with Jimmy giving her an impersonation of his pastor character. Kim tells Jimmy that his scheme with the phones was "genius", but Jimmy credits her with devising the whole plan in the first place. It is revealed that they have forced Ericsen to agree to Huell serving four months' probation with time served. Jimmy tells Kim that he plans to spend the day looking at another office space near the courthouse.
At Schweikart and Cokely, a bored Kim meets with Paige, Kevin, and one of Kim's associates. Kevin, noting that Mesa Verde's Tucumcari branch gets more foot traffic because of the building's "eye-catching" design, wants to use a similar design for their planned branch in Lubbock, Texas. Kim agrees with Paige that starting over the approval process over a proposed redesign is not feasible. Kevin accepts their opinion and turns the topic to a proposed branch in Wyoming, bringing up Yellowstone as he does so. After the meeting, Kim sits in her office and retrieves her Zafiro Anejo bottle cap -- a souvenir from her first con with Jimmy -- from a desk drawer and wistfully clutches it.
Underneath the laundry, Mike gives Gus a progress report on the excavation, telling him about how the recent accident caused by Casper has caused delays to the project. He also shows Gus a large rock that has been discovered in the middle of their planned elevator shaft, explaining that they must resort to blasting to remove it. Mike has already told Gus about the incident with Werner, and assures Gus that it won't happen again and that Mike is watching him.
Meanwhile, Jimmy is looking at the office space when Kim appears outside and knocks on the door. Outside, Kim tells Jimmy that she has been driving around "thinking about things." Jimmy assumes that Kim is angry about the crimes they committed to keep Huell out of jail -- which would have ruined them and Rich's firm if they were discovered -- and assures her that they are done with undertaking similar schemes. To his surprise, Kim tells him that she wants to do it again.
Upon driving up to El Michoacano, Nacho finds a nervous Krazy-8 sitting silently near the door. Nacho finds that someone has commandeered the back kitchen, cooking Mexican food while listening to loud music. The man identifies himself as Eduardo "Lalo" Salamanca, who has been sent to help Nacho run the Salamanca family's drug business. After offering Nacho food, Eduardo walks to the front of the restaurant and sits next to Nacho's seat, waiting to take collections.
- Taking into account the 62 episodes of Breaking Bad, Coushatta is the 100th episode in the Breaking Bad/Better Call Saul universe.
- In the beginning of the teaser, Jimmy mentions having a breakingdown in Amarillo, this is a reference to the time Jimmy orchestrated a bus "breakdown", so that he could solicit clients in the Sandpiper Crossing case. ("")
- According to Jimmy, the crimes he and Kim committed getting Huell out of trouble include exparte communication, contempt of court and hundreds of counts of mail fraud. As well, the con could've destroyed Kim, Jimmy and Richard Schweikart.
- His criminal behavior to follow is likely teased at the beginning of the episode on the bus as one of the cards has a cross on its cover, and gets inverted as Jimmy opens the card cover to read. As an inverted cross can symbolize unholiness, this likely foreshadows his sinful and deceitful behavior, especially as he later impersonates a church pastor.
- The Free Will Baptist Church's website is real: http://www.freewill-baptistchurch.com/
- The character of Lalo is introduced. First mentioned in the episode "" of Breaking Bad by Jimmy as Saul Goodman, he is revealed to be Eduardo "Lalo" Salamanca.
- As its revealed that Lalo is a Salamanca, it is hinted that Lalo may likely die sometime in the Breaking Bad timeline (or earlier) before "", as Gus taunts Hector that the Salamanca name dies with him, implying that all the other Salamancas are now dead. Though earlier in Better Call Saul, Jimmy/Saul thinks that Lalo is still alive, but he may not know of the latter's true fate.
