Jimmy screwed up with the " in Albuquerque you need a bail bondsman , in Nebraska you don't " raised eyebrows on Marion. Thought he was going to strangle Marion , at least tie her up, but the son has a record in NM and has to rat out Saul.
Kim never changed her name too easy to follow, and her loneliness, along with the suburban lifestyle festered guilt over the years .
Saul got cocky with the mall heists which made him more greedy and seemingly invincible. The cab was there, but i thought for a second he wanted to make it look like a smash and grab, he had the getaway but blew it.
Both Jimmy and Kim need each other in a twisted way, and slowly dissolve without one another.
Great observation with making the robbery look like a simple break in. I was wondering why Saul kept grabbing things, and didn't connect he was trying to distract and misdirect the broken window. Sure, the watches and stuff had value, but not that much, and he needed to get out of there.
