Walt’s breakdown after witnessing Hank’s death looked mighty similar to the flashback in which Gus witnesses the death of his “hermano” (as in, “Los Pollos Hermanos”) Max Arciniega at the hands of Tio Salamanca. Is this foreshadowing that Walt will seek revenge just as Gus did? Perhaps.
Also reminiscent? The text and imagery from the episode’s namesake, “Ozymandias.”
Half sunk, a shattered visage lies, whose frown
And wrinkled lip, and sneer of cold command
