The title of this episode, and the coded text message that Carrie receives from Franklin and responds to, come from the opening lines of a William Carlos Williams poem published in 1923. Only 16 words in length, and originally titled "XXII," the poem has become known by its most famous image. In a few brief, haiku-like images, the poem pictorially suggests an integral link between form and meaning, and the necessity of perception to life.
Dialogue in this episode suggests that the character of Mira is supposed to be significantly older than the actress who plays her (Sarita Choudhury). Mira tells Alain that she and Saul have been married 35 years. This episode aired in 2013 and Choudhury was born in 1966, which mean that a Mira who is the same age as Sarita Choudhury would have been 12 years old when she married Saul.
