Factual error: Enid, the telegraph operator, exclaims that "He is sending an SOS." However, in the 19th century, distress calls did not include the letters "SOS," It was not until the early 20th Century that SOS was chosen as the international distress call.goofyfoot
Factual error: In the opening scene for the episode, a character commits suicide by electrocuting themselves with a defibrillator. The device used was an AED (automated external defibrillator) which analyses the electrical rhythm of the heart and only delivers a shock when the heart rhythm is ventricular tachycardia or ventricular fibrillation. In this case, the device would not have delivered a shock as the person did not have both ECG electrodes attached and therefore would not have detected a cardiac rhythm. The person would also have had a normal heart rhythm.
Factual error: In the final scene with Peter and Olivia in Walter's campus housing, Peter uncovers items that should have been in the house for years and they are dusty. The last thing he uncovers is a brand new flat screen HDTV with stickers on it, which would not have existed 17 years prior to then, when he was committed to St Clarie's Institution.

Factual error: This series uses a beautifully-rendered CGI sequence of New Amsterdam C. 1650 morphing into New York City of the present day. The Native American tribe we see at the start of the sequence, however, never inhabited the New England area. They look more like the Lakota plains tribes seen in Dances With Wolves. The North-Eastern tribes didn't build teepees as seen here, either. The dwellings should be longhouse wigwams made of wood.Jean G
Factual error: The camera starts out-of-focus looking down a crowded sidewalk full of background actors in period clothes and hairstyles (1973). As the camera racks into focus, Sam is walking toward the camera with many awnings visible in the background - a large blue one reads "24 Hr ATM". Though versions were invented prior to 1973, they didn't come into wide usage until the mid-to-late-80's and certainly weren't available in East Village bodegas at the time of this episode.
