This is the first time that one of the Salamanca cousins speaks onscreen.
The entire conversation between Gus and The Cousins at Los Pollos Hermanos consists of just 9 words.
Walt pays Old Joe one hundred hundred-dollar bills for a grand total of $10,000.
After Walter prepares a sack lunch and sits down waiting for Walt Jr. to arrive, there is a fixture on the wall above Walter to the left: two checkerboard tiles linked by the corners, an homage to the "Br" "Ba" logo of the show.
Hank's reference "you didn't inhale" to Walter is taken from when Bill Clinton, when first running for President, was asked if he ever smoked pot, to which he responded yes, but that he didn't inhale.
