The Flash returns for its ninth and final season on The CW tomorrow night, though the show is only getting 13 episodes before wrapping up for good. That should be enough to end the Scarlet Speedster's story on a satisfying note, but showrunner Eric Wallace has confirmed that a lot of ideas failed to make it into the series...including an ending to Legends of Tomorrow!
That series was cancelled after season 7, with a cliffhanger and appearance from Booster Gold (Donald Faison). The show clearly won't have a place in the DCU, but had Wallace been given 20 episodes of The Flash as he originally hoped, the idea was to give the Legends a proper send-off.
"My original concept was to have at least one - if not a two-parter - that wrapped up Legends of Tomorrow," he tells The Nerds of Color. "And you know, there will be a little crossover we get them back, we get them out of time jail, all these good things, Booster Gold, etc, etc. When we found out we only have 13 episodes, that was no longer possible."
"We’re still writing a series finale so you never know what could happen at the very end. Hope does spring eternal, but I just want to put that over. All the Legends at least are all going to appear in an episode."
Hopefully, that appearance from the team goes some way in wrapping up their story in the Arrowverse, though the two-parter is far from the only ambitious plan Wallace had for The Flash. Had the show received a tenth season, he confirms that the series would have delivered both The Forever War and "The Blackest Night."
"I wanted to bring Despero with his alien friends and have a full-on alien invasion," he adds. "That would have featured the Justice League at the Hall of Justice coming in and helping Barry. We’re not going to do that either. So these things happen...We just took episode 200 and turned it into the series finale."
It's a shame in some ways that we won't get to see these stories play out, but The Flash has been running on fumes for a while and it appears Grant Gustin, The CW, and DC Studios were all in agreement when it came to ending the Fastest Man Alive's story this year.
The Flash season 9 premieres on The CW on Wednesday, February 8 at 8/7c.
