Character mistake: At the end of the episode when Grissom puts the news clipping up, the word "sacrificed" is spelled as "sacraficed" in the article.
Character mistake: When Nick and Morgan are commanding the dog to find the victim's scent (and the crime scene), they both use commands in French, e.g. venez (come), trouvez (find), allez (go), and restez (stay) - these are all formal versions of each verb. Why would they command in a formal manner?
Suggested correction: Because that's the manner in which the French train their dogs - they are ordering them to do something, not asking them.
