Continuity mistake: When Juliette comes back from being in a coma, it is made to seem like they only have 1 bedroom upstairs as Nick stays on the sofa for a while before moving in with Monroe. However, later in the series, when Trubel comes in, she stays in their guest bedroom.
Other mistake: It is right after dinner when Angelina and Nick leave for the bar, but when they get there it's daytime.
Factual error: Rosalee shows an old letter allowing her to contact the "Wesen Council" ; the letter is that of a law firm (Advocatenkantoor) in Amsterdam and the Hague. On the top of the letter instead of the correct inscription "Den Haag" we find "DeHaag" which is incorrect. (00:33:20)
Factual error: The assassin sent to kill Captain Renard carries a French passport which lists his place of birth as "Marseilles". This is an old-fashioned spelling of the name now almost only seen in North America. The French spelling is and always has been "Marseille".
Goodnight, Sweet Grimm - S2-E22
Factual error: There is a copy of a Czech passport shown when Renard reads the files sent from Paris. There is a typo in the place of birth which reads "Brastilava" instead of "Bratislava" (capital of Slovakia). Interestingly enough the name of the city is also spelt correctly on the passport just below, where it refers to the place of issue. (00:06:45)
