Why ‘The Flash’ Ended John Diggle / Green Lantern Storyline of ‘Arrow’

if The flash had your head spinning with the many recent revelations – including Tom Cavanagh’s Thawne nested in Matt Letscher’s, eww — the Season 8 finale will tie many (if not all) of the dots together.

Flash showrunner Eric Wallace tells TVLine that when the episode “Negative, Part Two” arrives Wednesday at 8/7c, “There’s a little bit at the top”, in which Cavanagh’s Eobard Thawne aka Reverse-Flash sheds light on how Iris’ tragic death ( by an ignorant Barry’s hand!) breathed new life and speed in the recently departed sinister speedster.

“And then you hear it in the words of the people who put this all together, the brains behind everything that happened in Season 8,” Wallace said. “You get an explanation from our ‘Big Bads’, the Negative Forces themselves (played by Christian Magby, Ennis Esmer and Sara Garcia), about why they do what they do, and why they did it nowwhich is pretty awesome.”

the explainer shall stop describing exactly when and how Iris got infected with time sickness in the first place, though.

“You get the basic time frame, and when and why [Iris was infected]Wallace says. “All those questions are answered. But you don’t get, ‘It happened on a Tuesday at 7 o’clock!’”

During TVLine’s in-depth Q&A with Wallace – most of which will be published Wednesday night after the finale – we also asked about the how/why Arrow hero John Diggle’s “Green Lantern”-y arc was recently brought to an end, and quite randomly, as The flashbuilt the season to its own climax.

Easy said, The flash was not renewed for season 9 until after the script for the finale was written, so everything that preceded it assumed the Arrowverse’s preeminent series wouldn’t be around much longer. So Wallace felt obligated to end Dig’s arc.

“We thought, ‘Oh my god, we have to do this because maybe no one will get the chance!'” Wallace told TVLine. “I spoke to David” [Ramsey] myself, and said to him, “I’d like to close this,” and he was all for it. And when I told him what we were up to, he thought it sounded great.”

Wallace says the June 15 wrap-up — in which Diggle declined the “cosmic” invitation made by the glowing cube he placed in Arrow’s series finale, before throwing the box into a void — also “served a greater purpose” by further teasing Blackest Night storyline from the comic books, which was previously encountered with The flash‘s mid-season introduction to the real Deathstorm (played by Robbie Amell).

But whether? The flash may ever go all in for that, Wallace is quite unsure, pending to know if season 9 will indeed be the last season.

“I’m a comic book nerd and I wanted to plant some” Blackest Night seeds, and that Diggle moment helped me do that,” he says. “But I don’t know if we’ll ever get around to it.”
