  • Trivia

    • When David visits Dwayne alone at the prison, the US flag filling the screen has 48 stars, so it is pre-1959.

    • Math used in this episode:
      Straddling Checkerboard
      Bacon's Cipher
      The Wheat and Chessboard Problem
      Knapsack Algorithm

    • The license plate on David's red Jeep is 5WHGO61.

    • This is the first time we see a Don vision when he sees the G major scale pattern on the bombs on the bridge.

    • Opening Numb3rs:
      6 BUGS
      7 BOMBS
      2 DAYS TO LIVE

    • Charlie cited 2^64-1 as being 18,446,744,073,799,551,615 but it is actually 18,446,744,073,709,551,615; by changing one digit, he added 90 million. Charlie did not detect the error and wrote it correctly on the wall later, so it was probably just a mistake on David's Krumholtz's part while reading out the number, perhaps because it was hand-written so the zero looked like a nine.

  • Quotes

    • Ashby: If you find The Janus List, trust it!

    • Charlie: Hey Don, what's going on?
      Don: I don't know, you got me. But we're about to find out.
      (Don turns on outward bound communications to Ashby)
      Don: This is Agent Don Eppes.
      Ashby: What was your Junior Year batting average?
      Charlie: .293
      Ashby: That would be your brother. I'd really like to meet him. Professor Eppes is out here in 7 minutes or the next bomb goes off.

    • Charlie: (trying to move Ashby when he sees a mystery man) So I have an FBI... you know, I work for the FBI.
      Lois: Can you protect him?
      Charlie: Well, actually I'm a mathematician.

    • Charlie: You know I'm always ready to help you no matter what.
      Don: So a face to face with this guy crosses the line?

  • Allusions

    • Don: He screamed something about a "Janus List."
      Allister: It's an old spy fiction--a master list of double agents and traitors.
      Megan: Janus, the two-faced Roman god. But how do you know it's a fiction?

      As stated, in Roman mythology, Janus was a two-faced god, and it was from Janus that both the name of the month January and the term "two-faced" originated. In this episode, the Janus List refers to of U.S. agents who are actually double-agents working for other governments. Despite Allister's claims of it being merely a fiction, it turned out to actually exist.

    • Alan: "Light many lamps and gather round his bed… "

      The lines quoted at the end of the episode are a slightly abbreviated version of the last two stanzas of Siegfried Sassoon's "The Death-Bed." The writers omitted the last three lines of the first stanza below.

      Light many lamps and gather round his bed.
      Lend him your eyes, warm blood, and will to live.
      Speak to him; rouse him; you may save him yet.
      He's young; he hated War; how should he die
      When cruel old campaigners win safe through?

      But death replied: 'I choose him.' So he went,
      And there was silence in the summer night;
      Silence and safety; and the veils of sleep.
      Then, far away, the thudding of the guns.

    • The bomber Taylor Ashby's poisoning was rather clearly an allusion to Russian agent turned dissident Alexander Litvinenko, whose poisoning made quite a few headlines in late 2006. The Russian government was suspect but never proved to be his assassin when Litvinenko a former KGB agent turned dissident attempted to publish a book critical of Vladimir Putin.
