Jimmy addresses Cathy as Khandi.
Correction: He doesn't call her Khandi, he calls her "Kathy", short for Katherine. Bill and Jimmy often call her Kathy. Khandi actually pronounces her name as "Kondi" (with an "O" sound)
Bill says, "Yours is not the reason why, yours is but to do and die - John Keats 1776" Actually it is a paraphrase of a line from "The Charge of the Light Brigade" by Lord Alfred Tennyson.
As Bill and Matthew discuss the handcuffs in Bill's desk, in the background Joe walks into scene, then he suddenly stops as if he is too early, and then he backtracks and steps out of view.
Why does Beth still earn, as she put it, "Next to nothing"? Just a few episodes earlier in the season she helped set Jimmy up on a date and he asked how much she got paid and she said very little and he said, quote, "That will be rectified."
