The end of an era happened on television in 2023 with the series finale of The Flash on The CW, which effectively ended the Arrowverse that had begun with just one show all the way back in 2012. At its prime (and not counting the divisive "Crisis on Infinite Earths" crossover event), the superhero universe was comprised of Arrow, The Flash, Supergirl, Legends of Tomorrow, and Batwoman. It's therefore fitting that Stephen Amell – a.k.a. Oliver Queen, the superhero who kicked off the Arrowverse – dropped a wonderfully nerdy Easter egg about The Flash's series finale.
