In this episode, Tony has never heard of Shane (1953), Alan Ladd, Elisha Cook Jr., or The Maltese Falcon (1941). Yet, in many other episodes, he is a movie expert, and usually the one to make references to movies, actors and characters.
Doctor Mallard explains that the emerald would have obstructed the intestinal tract causing perforation of the peritoneum leading to hemorrhage, infection and death.
A sharp object in the intestinal tract would first perforate it, directly causing hemorrhage, then infection and death. The peritoneum, which separates the interior of the abdomen from the muscular abdominal wall, would not need to be involved at all for death to have occurred.
When told there are 120 detainees and 20 barracks, Tony says the odds are 6 to 1 against his target being billeted in the same barracks. The probability is 1/6, but the "odds against" are 5 to 1. Probability is desired/total outcomes, while odds against is undesired vs. desired outcomes (and fractions are reduced).
Tony is supposedly sleeping in the nude when he wakes up to find an iguana in his bed. However, after Kate and Gibbs burst in, guns drawn, and find him naked, a bit of tape can be seen sticking up on his right hip.
Tony, later portrayed as a film expert, seems to have little knowledge of movies or movie actors. He recognizes neither "Shane" nor "The Maltese Falcon".
When the team learns that a son-in-law of Osama bin Laden is a detainee at Gitmo, Kate incorrectly pluralizes the phrase. She says "son-in-laws" instead of "sons-in-law".
