- Harsher in Hindsight: Walt Jr. angrily telling Walt "Why don't you just fucking die, already?" in this episode is meant to counter Walt's defeatist and suicidal attitude to his diagnosis, essentially being a verbal Get a Hold of Yourself, Man! slap. The next time Flynn tells his father to die is the penultimate episode as he angrily rejects his monetary offer and let's him know in no uncertain terms how much he now hates him and wants nothing to do with him. It's bitterly ironic how despite Flynn's frustration towards his father in this episode, had Walt actually just given up and died, Flynn would likely have had a higher opinion of his father than he winds up having at his death.
- Hilarious in Hindsight: The scene with Ken Wins, the asshole stock guy who got his car blown up by Walt, gets funnier knowing about the time that Jimmy and Kim Wexler tricked him into paying for an entire bottle of very expensive tequila.
- And, in another piece of Better Call Saul related trivia, hearing Hank mention Krazy-8's status as a narc becomes a bit funnier upon knowing the circumstances behind this. The DEA still never found out about Lalo's real plan, even though he's long dead.
