## Trivia

• ### Trivia

• It is stated that the drugs tampered with were over-the-counter medications, and that one of them was an asthma inhaler. Asthma inhalers are only available by prescription and cannot be purchased over the counter.

• The Steiner Tree method may find the shortest route(s) between a set of points. HOWEVER it's not suitable for finding the route that a given person may be taking, because the person will only be taking the route if he's aware it's the shortest. A normal person will take a familiar route between two points. He may refine that route over journeys if he finds shortcuts - but he may go for years or never find that there was an even shorter route available... unless he uses similar mathematical techniques.

• The MATH:

The Steiner tree problem is a problem in combinatorial optimization. It is superficially similar to the minimum spanning tree problem: given a set V of points (vertices), interconnect them by a network (graph) of shortest length. The Steiner tree problem is to solve this problem when adding new vertices is permitted before finding the shortest network connecting them.

• The foundations of negotiation theory are decision analysis, behavioral decision-making, game theory, and negotiation analysis.

• Charlie: ...but information theory indicates there is a connection.

Information theory is the mathematical theory of data communication and storage founded in 1948 by Claude E. Shannon. Modern information theory is concerned with error-correction, data compression, cryptography, communications systems, and related topics.

• Colby Granger's hometown is Winchester, Idaho.

• There's some continuity problems with the torch at end of the negotiation between Megan and Bob McHugh. At the last shot from behind the torch you see a small flame, but in the shot before and after this there's a large and wide flame, like the torch is about burn out.

• ### Quotes

• Ian: (Pointing at Charlie's scratchings on the sand) Does this mean anything to you two?
Don: Yeah, only that he's probably right.

• Edgerton: (greeting Don and Charlie) Professor and Agent Eppes, how can I fail to learn something today?

• Don: Hold on! What are you doing?
Megan: I'm a women. To a mountain man like Mchugh, I'm less of a threat.
Edgerton: She's got a point.
Don: She could also kick his ass but he doesn't know that.
Megan: (laughs) I see what kind of big brother he was.

• Don: The Marshalls come to arrest him, he barricades himself inside the house. Four days later in the middle of a negotiation for no apparent reason he opens fire.
Edgerton: When did crazy stop being a reason?

• Charlie:(To Larry on picking Charlie's brain) You're more than welcome to whatever scraps my brother leaves behind.

• Charlie: It's not like I can whip up a magic formula for every single problem.

• Colby:(After being introduced to Agent Edgerton)That's Edgerton?
David:Yeah,you know him?
Colby:That guy was a sniper legend in Afghanistan. You'd see his work everywhere, but you'd never see him. A colonel in special ops said he was the bastard son of Clint Eastwood and Yoda.
David:(laughs)I'll get you his autograph.

• Don: (to Larry) Hold on... you and Megan went out to lunch?
Alan: (sardonically) Please tell me you ordered something other than white food!

• (discussing gamma rays)
Larry: A gamma ray burst will release more energy in 10 seconds than the sun will emit in its entire 10-billion-year life span.
Don: Wait I got it... What's The Hulk's real name? Bruce Banner! Didn't gamma rays turn him into The Hulk?
Larry: (opens front door) They come from the furthest ends of the universe and after 45 years we are still uncertain of their origin.
Alan: And...?
Larry:(smiling) And we're closer to an answer on that than the three of you are ever gonna get on this.
(Larry leaves)
Charlie: Megan?
Don: And Larry...
Alan: Now there's an image!
(everyone laughs)

• Agent Edgerton: (to Don and Charlie) I always have the best time with you guys.

• Alan: (working crossword puzzle) Okay... 8-letter word for "egotistical."
Charlie: "Conceited"
Alan: "Conceited" is a 9-letter word.
Charlie: (spelling) C-O-N-C-E-T-E-D
Alan: (perturbed) Another person might think that our educational system has failed you completely, Charlie.
