Stop Me Before I Hug Again - S1-E13
Character mistake: In Brian's "Laws I Have Broken Since Joining FBI" list, item #30 misspells the word "recorded" - "30) Recoreded NFL Game Without Consent." He'd only have that knowledge if he was using NZT, and if he was, he wouldn't make a mistake like that.

Character mistake: A shot shows Djimon Hounsou completing his year entry on a large chalk board. The entries are 20 years apart. The third entry on the second line is 2274, the next should be 2294, but instead it records 2394. The one after corrects the sequence with 2314. Considering there is an entry only every twenty years, you would think he'd be more careful. (00:20:15)
Character mistake: Congressman Weitz tells the FBI task force that Kazahrus is an "absolute monarchy." Director Hirst interrupts him to state that this means "the order of succession is based solely on heredity," which she implies is well-known to students of civics. An absolute monarchy is one where the monarch's powers are unrestricted (such as by legislative or judicial branches of government). Hirst is describing a hereditary monarchy, but not all hereditary monarchies are absolute (for example, England's constitutional monarchy is hereditary), nor are all absolute monarchies hereditary (the Vatican's elective monarchy is absolute). What Hirst says is true of Kazahrus, but not of absolute monarchies, the term Weitz was defining. Weitz is presented as an expert on the topic, but doesn't correct her.
Character mistake: In an early episode, Villa mentions Rosewood's "banana colored" '69 GTO to his then girlfriend. Rosewood's GTO is a "banana colored" '68 GTO.
