Continuity mistake: In the scene explaining the history of the missing jade elephants, they are described as being given to ambassadors by the emperor Zhu Di of China when the Forbidden City (in China) was first opened to foreigners in 1421. When the elephants are all brought together, the representative Daichi Yoshida from the Japanese embassy comes to pick them up, describing them as "a priceless piece of our history."Rachel Weldon
Factual error: In the banner for the exibition in France at the start, the French isn't right. It says "Opéra nationale" and "La morte de Marie Antoinette Des objets fabriqués de le temps de Marie Antoinette". It should be "Opera national" and "La mort de Marie Antoinette Des objets fabriqués à l'époque de Marie Antoinette" or "des objets fabriqués du temps de Marie Antoinette".
Factual error: At the beginning of the episode, Patrick Swayze is looking at photos of two Iraq veterans who have been murdered. He identifies one as a Marine Lance Corporal and the other as an Army PFC, but both pictures show men in U.S. Army uniforms. A bit later, his partner, who is supposed to be a Marine vet, refers to his decision not to "re-up," using the Army term for re-enlistment, rather than "ship over," as it's referred to in the Navy and Marines.
