Name correction
1 May 2007 | by (France) – See all my reviews

In this episode, the name of the bad guy being chased by the NCIS team is erroneous in the plot outline. Indeed, his name is pronounced with the English accent, and thus mislead the author of the episode description. It in fact La Grenouille , meaning literally, in French, The Frog, hence the nickname Frog - a common pejorative denomination of Frenchmen by Englishmen, and thus a little irony on behalf of the writers - given to him by Gibbs.

This information is pretty important I believe, as there is a history of Gibbs and Jenny having worked in France (see previous seasons)


In this episode, we discover through Ducky's psychological investigations that Jenny had indeed a past with La Grenouille, though there it is not mentioned to what extent this relationship had grown. Therefore, there may be a link between the French origin of the arms dealer La Grenouille and Jenny's past in France.
