This episode really made you feel how close we're getting to Breaking Bad territory. Obviously, the appearances of Madrigal and Lydia helped that, but the storylines are really crossing over in a way that you can feel Walter White around the corner.
The interaction between Mike and Saul evokes Mike's original role as the official "cleaner," where you can easily picture Saul asking him to get involved in the Jane situation. Similarly, Mike's conversations with Nacho are right in the realm of his relationship with Jesse. Plus, Saul's breakdown at the end really echoed the more unhinged sleazeball we see in BB.
This show has been such a surprise all the way through. I can't believe we're over halfway through season 5 and Jimmy is just now going by "Saul" full time, still doesn't have the Cadillac, and still doesn't have the office, and yet it feels like the intersect is coming soon, and I'm still satisfied with the journey. It's nuts how the show has been allowed to breathe as much as it has without meandering for a second.
