In the promo, which you can view below, we gaze over the New Mexico desert as we listen to Bryan Cranston read "Ozymandias," an 1818 sonnet by Percy Bysshe Shelley.
I met a traveller from an antique land
Who said: "Two vast and trunkless legs of stone
Stand in the desert. Near them on the sand,
Half sunk, a shattered visage lies, whose frown
And wrinkled lip and sneer of cold command
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed.
And on the pedestal these words appear:
'My name is Ozymandias, King of Kings:
Look on my works, ye mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare,
The lone and level sands stretch far away."
The poem refers to the hubris of drug lords — oops, sorry — rulers who assume they and their work are immortal and yet are reduced to dust all the same. (Paging Walter White!)
Looks like our favorite chemistry-teacher/high-school-dropout duo are bound for a fall in the show's final stretch!
