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: Nate's dad, played by Thomas F. Wilson, says "let's make like a tree and leave", to which Nate replies "I'm not sure that's how it goes." Thomas F. Wilson famously played Biff in the Back to the Future films, who frequently got that saying wrong.
Question: Why don't the heroes use at least 2018-era protective gear to keep from getting shot or stabbed?
