One of my questions early in the Better Call Saul series was, Who's Kim? Specifically, what's her relationship with Jimmy? It was obvious from the start they're friends... but not clear at what level. There was a close camaraderie almost like they were best friends who grew up together, but there was also a sexual tension that was unresolved. Were they exes who'd stayed amicable? Just good friends? Just good friends, but Jimmy was looking to get in Kim's pants? Friends with benefits (already)?
Their relationship did become sexual back in (I think) season 2 and matured from there into one of partners living together. But as it turns out the best description of their relationship is that they're each other's ride or die. And that makes it extra sad that their joint story arc in season 4 is one of growing apart.
The showrunners tell the story poignantly in a split-screen montage at the start of episode 4.07.

Jimmy and Kim are shown going through the mundane motions of life, brushing their teeth in the morning, eating dinner in the evening without talking to each other, and lying down separately to sleep in the evenings. Occasional shots of dates on paperwork show months are passing. Jimmy and Kim still live together, but in most of the clips they're not together together; they just happen to share an apartment.
BTW, many critics and fans criticize the showrunners' use of flashbacks, flash-forwards, and time-is-passing montages. This show and Breaking Bad have used these devices frequently. The complaint is that there's an over-reliance on such devices. It's true, the creators seem to like these devices. But what the "too frequent" criticism misses is that these showrunners routinely do it well. This opening montage in episode 4.07 is one of the most compelling, and saddest, time-is-passing montages I've seen. (The only sadder one, frankly, is the opening minutes of Up!. OMG what a sad way to start an animated feature.)
What's going on here is more than just mundane routine such as eating meals. Jimmy and Kim have actually been growing apart all season, as their careers develop in different directions. The montage shows clips of this, too.

A big part of Jimmy's story in season 4, as I've noted a few times already, is dealing with the one-year suspension of his license to practice law. He finds a job selling mobile phones— but turns it shady and gets into hot water with it. Meanwhile Kim's law career is taking off. She does stumble for a bit early in the season as she questions her purpose in helping regional bank Mesa Verde, her sole client, grow bigger. In her search for purpose she starts doing pro bono work for the public defender's office. It distracts enough from her banking work, though, that it jeopardizes her relationship with Mesa Verde. But she goes to Rich Schweikart, head of Schweikart & Cokely, and offers to bring them a new banking division with Mesa Verde as its first customer. Rich hires Kim as a partner at his respectable firm and makes her manager of a team. So while Kim and her team are working with a senior partner and a bank owner to review plans (left panel above), Jimmy (right panel above) is hawking phones to criminals out the back of a van in a dirt parking lot.
It sure seems like Kim and Jimmy are headed in different directions professionally... and, ultimately, personally. Are they headed to splitsville by the season finale?
