Factual error: There is a periodic table shown in the background of the lab, showing an accurate periodic table as of now. During 1945, at least 21 elements had not been discovered. (00:17:40)
Continuity mistake: When the alarm in the office goes off, there are clocks visible around the alarm. The time on the New York clock is 10:40. About 15 seconds later, as the agents go into the meeting room, the New York clock has gone back 5 minutes to 10:35. It is definitely the same clock because the alarm is visible next to it. (00:03:40)
Character mistake: When the office receives a code red alert, there is a close-up shot of the alarm, where there are two clocks next to it. One of the clocks represents New York time. The other represents London time. The clock representing New York reads the time as 10:40 and the clock representing London reads the time as 4:40. The time difference between New York and London is 5 hours, not 6 (occasionally 4 due to DST). (00:03:40)
Suggested correction: London is five hours ahead of New York normally, but Episode 5 takes place on April 25, 1946, so it is reasonable to assume Episode 1 takes place not long before that. England went on British Summer Time on April 14, 1946, while New York didn't go on Daylight Savings Time until April 28, 1946, so from April 14 to April 28, 1946, London was 6 hours ahead of New York, so the clocks would be correct.
