Speculation abounds about what storylines will be included (and how closely it will follow the comics), but TV Guide can reveal one key element from The Flash that next year’s crossover will focus on: The future news headline that’s been hanging over The Flash for nearly five seasons now: “Flash Missing, Vanishes in Crisis.”
“We’ve certainly been teasing [the headline] a long time, but it’s a major factor in next year’s crossover,” The Flash showrunner Todd Helbing recently told TV Guide.
We’ve just barely left the Arrowverse Elseworlds crossover behind, but we’ve already got our minds turned toward 2019’s crossover, known as Crisis on Infinite Earths.
Beyond the title, which was revealed at the end of the Elseworlds crossover, we know next to nothing about Crisis on Infinite Earths.
