Character mistake: When Matt is talking to his priest Father Lantom, he says "it was a nice sermon" instead of "it was a nice homily." In the Catholic church "homily" is the correct word; sermons are Protestant. (00:11:30)
Character mistake: The diploma on the wall in Connor's office for the University of Kentucky, "university" is misspelled "universisty".
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: After Nick kills Calvin, and Travis arrives, Nick calls Travis "Nick" before correctly calling him Travis in his next line of dialogue.
Blood Drive - S2-E6
Character mistake: Zayday makes incorrect statements about blood types. She mentions that, since Chanel #5 is type O-, her parents must also be O-; in actuality, they could each be type A or B (genotypes AO or BO, respectively) and could also have Rh+ blood as long as they also carry the recessive Rh- allele. Zayday also says that the child of two O+ parents must be O+, but actually the child could also be O- (again, if the parents carry the Rh- allele).
Character mistake: When trying to decipher what the letters from the dermal implants spell, Lucifer rearranges the letters and says "Hilii Fircus, it means 'children of the goat.'" However, the correct phrase was Filii Hircus, not Hilii Fircus. (00:13:27)
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: When Juliana puts the film on the projector she loads the reel backwards.The film is supposed to drop from the front of the reel, not the back.
Character mistake: President Marsdin says that Camp David was named by President Eisenhower in honor of his son and grandson. It was actually named for his father and his grandson; his sons were named John and Doud.
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)
What a Tangled Web We Weave - S6-E13
Character mistake: Dr Choi addresses April as Maggie. (00:22:51)
Suggested correction: He never uses either name. He says "hey" in a hushed voice.
Until Sunset, the Full Moon - S1-E7
Character mistake: Zenigata uncovers Elena's arm saying he noticed the mark when she was fighting "those guys previously." Which guys? Her assailant was just one dude. (00:13:40)
A.K.A I Have No Spleen - S3-E3
Character mistake: Jeri asks Kith what an open marriage is. She's a sexually promiscuous experienced New York lawyer, middle aged...there's zero chance she needs that defined for her.
Character mistake: When the office receives a code red alert, there is a close-up shot of the alarm, where there are two clocks next to it. One of the clocks represents New York time. The other represents London time. The clock representing New York reads the time as 10:40 and the clock representing London reads the time as 4:40. The time difference between New York and London is 5 hours, not 6 (occasionally 4 due to DST). (00:03:40)
Suggested correction: London is five hours ahead of New York normally, but Episode 5 takes place on April 25, 1946, so it is reasonable to assume Episode 1 takes place not long before that. England went on British Summer Time on April 14, 1946, while New York didn't go on Daylight Savings Time until April 28, 1946, so from April 14 to April 28, 1946, London was 6 hours ahead of New York, so the clocks would be correct.
Looking for Mr. Goodbrain, Part 2 - S3-E13
Character mistake: When Liv and Clive are talking to Chase about Katty, Liv tells Chase he had a cocktail napkin with Katty's phone number on it. However, it was only Katty's hotel room number that was on the napkin, which Liv saw.
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.
Suggested correction: Travis is the one who says "Nick".
