Since The Flash episode will serve as the midseason finale, and before the Arrow and Legends of Tomorrow episodes conclude the highly anticipated event in January 2020, it’s likely that it will end in Barry’s foretold disappearance.
We know the five-hour crossover will be split into two parts, with the first three episodes of Batwoman, Supergirl and The Flash airing ahead of the winter hiatus.
The Flash’s Season 6, Episode 2 title has been confirmed to be “A Flash of the Lightning,” which is a nod to a miniseries issue for “Crisis on Infinite Earths.”
Of course, there’s still a huge possibility that Oliver will ultimately be the one to die, especially because Season 8 of Arrow is its last.
