Do You Take Dexter Morgan? - S3-E12
Other mistake: The marriage certificate for Rita's first marriage shows her date of birth as 04-19-1989 and Dexter states she married at 16. The marriage date is 08-16-1989, when she would have been 4 months old. She also would only be 17 at the start of the series (2006) if she was born in 1989. (00:13:45)
Other mistake: The registration number of the Ford Zephyr police car is RVP154G but the security etching on the window reads EKM414C.
Other mistake: In this episode, Shawn supposedly impresses Jules at their first meeting by "divining" facts about her family and cats. We never hear about the cats again and later learn that her parents have not been together for 30 years.
Other mistake: Captain Eureka losing his finger makes absolutely no sense. He doesn't cry out in pain, there's no blood, and where the finger ended up is completely illogical. The finger didn't just sever on its own; it's shown that severing only occurs when passing through objects. Captain Eureka goes through a wall that is a good fifteen feet away from where the finger is discovered, and it is implausible to think it could have rolled there on its own.
Other mistake: The T.V. begins to work and you see a Chinese man with a map of the United States behind him. The cities that were destroyed were bulls-eyed on the map. Wichita was not bulls-eyed on the map, but Emily seconds later is crying in a car saying that her fiancee is dead because Wichita had been hit and she "saw it on the map."
