Living Doll - S7-E24
Revealing mistake: Grissom and Brass enter the darkened apt. and Grissom spots another doll figurine on the book shelf as Brass takes notice of the dead guy on the bathroom floor. As Grissom comments on this being yet another 'miniature killer' scene, the cam flips to a shot of Dead Guy and he wiggles just slightly, even though he's supposed to be dead.

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.
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.
Plot hole: Amanda Haynes is Lacey Duvall's murderer, however in the opening scene she was kissing Patrick Haynes at the party downstairs at the exact time Lacey fell into the pool. She could not have pushed Lacey upstairs. (00:01:16 - 00:41:29)
