The flower shown in the first scene is a desert blue bell; they symbolise humility and everlasting love.
This is one of only two episodes to not feature the show's regular outro music over the end credits (the other was Lantern (2017)).
The blue desert flower in the opening shots is commonly called a "Canterbury Bell" and is native to the Mojave and Sonoran Deserts.
The episode's cold open was shot simultaneously with the oil tanker scene on a different soundstage, where they added a 40 by 40 feet patch of desert, with a green screen in the background. It took two days to prepare, and was shot using a motion control rig.
At the end, Jimmy and Kim head to dinner at Taco Cabeza. Taco Cabeza is the location that Jesse mentions to Walt for meeting up to do drug sales in early episodes of Breaking Bad (2008) instead of the junkyard.
