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)
