Rust Cohle (Matthew McConaughey) references Keatsian negative capability: “You just look at somebody and think like they think, negative capability. I mean, I guess it's a skill. Most times, you don't even need that. You just look them in the eyes. The whole story is right there.”
This episode was written by Gilbert Ralston and Gene L. Coon, and directed by Marc Daniels. A 2013 fan produced sequel, "Pilgrim of Eternity", continued the allusion, by using the title given to Byron in the poem.
“Adonais” is quoted in this episode: “Do you believe in fate? I don’t mean justice. I mean retribution. Facing the consequences of your actions that have produced catastrophe. A sin that is everlasting, one that you have made immortal. There is a line from Shelley that haunts me, a single line from Adonais. I cannot get it out of my head. ‘No more let life divide, what death can join together.’”
In this episode, character Vanessa Ives (Eva Green) quotes “Darkling I listen; and, for many a time / I have been half in love with easeful Death, / Call’d him soft names in many a mused rhyme, / To take into the air my quiet breath.”
