This was going to be the last show of the series, as NBC announced on Wednesday 5/10/2017 that it was being canceled. However, the internet "erupted" with protests the next day, and the network's response was unprecedented. On Saturday 5/13/2017 NBC "uncancelled" the show and ordered 10 more episodes.
The episode takes place on February 20, 1954 with the episode originally airing on February 20, 2017.
Lucy reminds Wyatt, "It's 1954. You'd be arrested for being gay." That was also true in 1964, '74, '84, and '94. It wasn't until 2003 that the Supreme Court ruled homosexuality legal.
