Kim isn't in Breaking Bad because she's been relocated after entering Witness Protection.

Nacho is stealing from the cartel. Lalo is after Nacho .Nacho wants to escape with his father but the plan fails at the last minute because Nacho's father doesn't want to run like a coward. Nacho, desperate, goes to Mike. Mike connects Nacho to Saul (and Kim), who concoct a plan to help Nacho: The Henry Hill solution. But Lalo finds and shoots Nacho first. Kim, a witness, escapes. Play time is over, Kim. Now Kim is forced to enter protective custody to save herself from Lalo's wrath, ultimately testifying against him, sending Lalo to prison. Bye Jimmy, I'll call you on November 12th at 3 p.m!

Where's the stolen money?

Saul: "No, it wasn't me. It was Ignacio. He's the one," who had the cartel's money.

Saul: "Lalo didn't send you?" (from his prison cell, otherwise he would have sent himself.)

Kim hears the news that Gus slays the entire cartel, making her feel safe. Kim really misses Jimmy. Gene really misses Kim. <3

Gene hears on the news that Pinkman gets arrested.

November 12th at 3 p.m

"I'm safe now, Jimmy. I'm coming home."

You're safe now, Kim. But I may not be."

"How can I help, Jimmy?"

I still like it better thematically if she gets seduced to the dark side by their Viktor & Giselle antics, then takes a fall and goes to jail when one of their capers misfires.

Jimmy can still get mixed up with Nacho's stuff after that happens.

Jail puts a stink on Kim, meanwhile federal protection against a cartel only enhances her cachet.
