“Amarillo” incorporated a ton of thematic material from the first season of Better Call Saul, and in doing so became a pivotal chapter in the hilarious, sad tale of Jimmy McGill. There are callbacks to nearly every episode. Jimmy casts a spell on his phone as he did throughout the first season, starting in “Uno“. We have the return of the dimwitted film students from “Hero” and the Alpine Shepherd Boy from “Alpine Shepherd Boy“. Mike chomps on the same sandwich from “Pimento” and sits outside his daughter-in-law’s house as in “Five-O“. At one point Jimmy even whispers bingo as if to say, hey, we had an episode called “Bingo“.
Details like this are nothing new for Saul, and they don’t even take into account the hundreds of little callbacks/foreshadowing to companion series Breaking Bad (like Kaylee’s little pink elephant). At best, the high degree of subtlety with which these are employed makes for what Jimmy would call a rich tapestry, a comprehensive and highly believable narrative that can afford to veer into ridiculousness in plot due to the strong foundation of details and character quirks. At one point in “Amarillo” Jimmy approaches Clifford Main’s office and pauses outside the door. We hear faint guitar chords and then Jimmy walks away. The inclusion of those chords — which we know are from Clifford himself after his explanation in “Cobbler” — isn’t necessary by any means, but it reinforces the history behind the scene enough that we feel the history as Jimmy does.
