Continuity mistake: When Nigel spots the skeleton inside the Buddha statue, in its close-up it is lit very differently compared to the rest of the scene. (00:29:30)
Revealing mistake: When the captain shoots the man that flees the scene in panic, there's no sign of a wound, burn mark, or tear on the victim. (00:03:20)
Revealing mistake: In Bodh Gaya, Sydney knocks out Stewie Harper with a straight punch of supreme cartoonish phoniness. (00:20:30)
Other mistake: When looking for the floor where the diamond is cut Nigel sees a sign which he translates as "Brown Duck." The sign however is misspelled Bruin Eend Kleren. In Dutch it would have to be Bruine Eend Kleren. (00:37:25)
Plot hole: Sydney is able to surmise from the artwork (we could also say from the writing, but her rival is one step ahead of her for 2/3 of the episode and it is established that he does not know the language) the precise location of the koi in Lumbini. The map is 150 years old, but there's no way even with a big stretch of imagination to buy that they both'd be able to pinpoint with such ease and certainty its location in the basement of a random building in the bustling market center of a town, that surely changed plenty during the past century and that does not bear any special landmark.
Factual error: On a lorry for Lumbini, Nigel comments about this being his first day of work. Even assuming that Nigel and Sydney met first thing in the morning and they just took off for a flight that was leaving for India really soon, it is a flight that takes 17-20 hours. Even considering the time difference between "the US" (the actual location is never specified) and Bangalore (closest hub to their Nepali destination), it is really a stretch, since it's impossible that he did not sleep during the flight, and of course it's just hilarious that they'd have a chat about it only after an intercontinental flight.
