The question now is "what do they do for five more episodes?"
Kim is going to see Saul sending her on Lalo's "errand" as a massive betrayal. This is going to be the giant "step to far" in the shenanigans they have been pulling, esp. with Howard's death and Mike telling them to keep telling the lie that they started (oof).
As I posted upthread, I think Kim will eventually go the Saul (in BB) route and get a new identity/life somewhere else. She's either going to somehow face indictment for Howard's death, or stupidly get caught up in Fring or Salamanca's business and have to disappear.
I think the most brutal/brilliant part of that episode was that Lalo breaking into Saul's apartment, shooting Howard, and sending Kim off to kill Gus was JUST A RUSE to get security away from the laundromat. That is a cold-ass calculated motherfucker
