Character mistake: As Reddington sets up the blood transfer between himself and Ressler he inserts the intravenous line in Ressler's arm first and then in his own arm. This way the remaining air inside the line gets into the recipient's body and could very well kill him. Judging the expert way he handles the set up he should know to first insert the IV in his own arm, let the line fill with blood and then insert the IV in Ressler's arm.Lenore Scott
Character mistake: When Aram wears the CDC hazmat suit, the CDC personnel advises Aram that he has 20 minutes of air to keep him alive, making the mission time critical. What she says additionally is that "oxygen levels plummet and carbon monoxide (CO) levels rise" CO is not a byproduct of human respiration - carbon dioxide is.
Character mistake: After the seaplane crash lands off the coast of Havana, Elizabeth radios a mayday. However, she broadcasts nonsensical coordinates. The first set she provides is 23°52' north, the second set 82°49' south. These combined coordinates can't possibly plot to any location on earth. The more probable coordinates should've been 23°52' north, 82°49' west. These coordinates would put the plane roughly 57 miles NNW of Havana, Cuba. (00:05:48)
Character mistake: After Elizabeth and Alexander Kirk crash-land into the Gulf of Mexico (technically, the Straits of Florida), Lizzie gets on the radio to report mayday, along with their coordinates. She incorrectly states their position with the following statement: "Mayday, mayday. Plane down off the coast of Havana. 23 degrees, 52 minutes north, 82 degrees, 49 minutes south. Mayday, mayday, mayday." Those coordinates specify two different latitudes (one above the equator, and one below), but no longitude! Luckily, she DID say they were off the coast of Havana, so the Coast Guard would be able to deduce the correct coordinates of 23' 52" north, 82' 49" west (not south!). (00:05:45)Zgozvrm
