The Flash Season 5 Finale Will Set Up Crisis On Infinite Earths

The Flash Season 4

We’ve known that Eobard Thawne was up to something for the past half-season on The Flashbut now Barry Allen and his friends from STAR Labs have discovered the extent of his master plan: to get his enemies to defeat Cicada, thereby destroying the metahuman-dampening dagger that’s imprisoning him in the future Central City of 2049.

Showrunner Todd Helbing spoke to TV Line to explain the situation a little more recently and elaborated on Ralph’s realization of the truth based on something not adding up about their plan to destroy the dagger.

“In the history of Cicada there was a point where Young Grace woke up, and that whole time Cicada was killing people. So now that they gave him the cure, what happened to all those people he continued to kill?”

Helbing also reminded viewers of something Thawne said way back when which now gains a new significance.

“The first time that Nora goes to Iron Heights, he’s talking about the power dampening in the cell. It’s the dagger he’s talking about.”

Moving on to how the season 5 finale will set up next year, the showrunner promised that there’ve already been many easter eggs teeing up what’s going to happen in season 6 and this will come to a head in the last episode.

“We’ve been dropping Easter eggs, especially in the back half of the season, about next season. It all plays into that.”

Speaking of things season 5’s been foreshadowing, there’s been an awful lot of references to the events of “Crisis on Infinite Earths,” the crossover to end all crossovers that’s due to change the Arrowverse as we know it forever this fall. Will the finale set up the multi-part storyline, though? TVLine asked Helbing this very question and he gave an exciting answer: “Yes, it does. Totally.”
