  • Spencer Reid: "Just as the constant increase of entropy is the basic law of the universe, so it is the basic law of life to struggle against entropy." — Vaclav Havel


  • In physics, entropy is a thermodynamic quantity that represents the unavailability of a system's thermal energy for conversion into mechanical work. The term is often interpreted as the measure for disorder or randomness in the system, and has also been used as a word for "lack of order or predictability; gradual decline into disorder".
  • Harry & Glenn's Grill and Bar, the primary setting of the episode, was named after show producers Harry Bring and Glenn Kershaw.[1]
