  • Episode Description
  • While consulting with the NTSB at the scene of a wreck, Don learns that this tragedy is one of a series of recreated accidents involving railroad negligence. As is the pattern with the previous train wrecks, an undecipherable numerical code is left at the site, which Don recruits Charlie to solve. Don's investigation leads him and his team to a dangerous standoff with their suspect, who has surprising ties to the railway system.moreless

    • Charlie: It's not a code. It's a story told in numbers.

    • Alan: Is that Amita sitting in the car out front?
      Charlie: Yeah. We just stopped by for a minute so I can check this text on encryption and code breaking.
      Alan: And you left Amita waiting in the car? No. No. This is not the way we treat people, Charlie. You bring her inside, you at least offer her something to drink. You know, like an adult.
      Charlie: We just stopped by for a second.
      Alan: You came in 15 minutes ago, Charlie.

    • Alan: Well, it seems like your new math consultant is working out nicely.
      Don: I gotta tell you dad, I can’t think of anyone who could have helped us the way Charlie did in this investigation.
      Alan: You just remember how Charlie is. Can’t seem to quit a problem. He’s still working on the same one he’s had since grade school.
      Don: And what’s that?
      Alan: Trying to impress his big brother.

    • Don: I want you to know I don’t take for granted what you do.
      Charlie: I never thought you did.

    • RR Investigator: If it is a code, it’s unbreakable.
      Don: I wouldn’t count on it.
