Factual error: At the beginning of the episode, when Snart steals the female soldier's keycard in 1986, she is wearing the U.S. Army's Combat Infantryman Badge (CIB), a combat award for infantry and Special Forces soldiers. It is not possible for a woman to have a CIB in 1986 because women were not eligible to join the infantry or Special Forces until 2016.

Left Behind - S1-E9
Factual error: Ray, Sara, and Kendra are Left Behind in 1958. However, 10 weeks later Sara and Kendra are playing the board game "The Game of Life." The modern version, as seen, didn't come out until 1960 (previously it was called The Checkered Game of Life and doesn't resemble the modern version).
Leonard Snart: This isn't my first prison break.
Trivia: When Zari says she'll agree if the team helps break her brother out of A.R.G.U.S., Rory replies "Prison break. I'm in" Dominic Purcell and Wentworth Miller (who play Rory and Snart) both stared in the TV show "Prison Break."
Question: Not sure if there's an answer, just speculation, or a plot hole. As I understand it, the premise of time travel in the show is the Legends can't go back to a time they've already been to because then time would fold in on itself, etc. For example, the 3 get stranded in 1958, picked up in 1960, but the rest of the Legends can't try again by just going back to 1958. But then it's revealed that Chronos was Rory all along, so how is Chronos/Rory able to time travel back to a time Rory has already been to without doing any real damage to time? And if the idea is, well no-one knew Chronos was Rory, so they didn't know they were interacting with a time traveling version of themselves (or what ever the reason), then all the Legends have to do is disguise themselves to interact in the same time.
Answer: My speculation... As Chronos was sent by the Time Masters, the armour he is given may have some sort of 'time folding preventive' system built into it? (A pure assumption on my part).
