SPOILER WARNING: This article contains major spoilers for "Memorabilia," the latest episode of The Flash.
The Flash may have just dropped a major hint about its upcoming storylines. In "Memorabilia," the latest episode, Barry and Iris toured the Flash Museum when they visited their daughter Nora's subconscious. While they were there, they walked past two real-life The Flash comics, which may tease pieces of the show's future.
The two comics in question are 2001's The Flash #172 by Geoff Johns, Scott Kollins and Doug Hazlewood and 2018's The Flash 39 by Joshua Williamson and Carmine Di Giandomenico. With a subtitle decrying "The Cult of Cicada!", the former's presence on the series makes a lot of sense. The latter, however, promises "Grodd is Back."
In The Flash #172, the Scarlet Speedster finds himself at the mercy of Cicada after Cicada's cult kidnaps him. Of course, the comic book storyline saw Cicada's cult killing all the people Flash ever saved. On the show, however, Cicada is on a mission to kill every metahuman in Central City and he most certainly does not have a cult. Thanks to recent developments in "Memorabilia," though, that could change.
During "Memorabilia," Nora went into Grace's subconscious in an effort to wake her from her coma. Because of her injury, Grace's brain is flooded with Dark Matter, allowing her to trap Nora inside. As soon as she realized Nora is a metahuman, Grace tried to eliminate her. Despite being in a coma, Grace has been aware enough that she has overheard her uncle Orlun Dwyer and Dr. Ambres discussing the metahuman "threat" and the fallout of Cicada's battles with Team Flash. As such, Grace bears a grudge against metahumans.
Seeing as Grace has been impacted by Dark Matter, she could have a few powers of her own; if she were to develop powers, they would likely be mind-based because of the nature of her injury. Combined with her newfound mission to help her uncle, she could possibly influence other people to turn on the Flash. As it stands, he already has something of a following between Grace and Dr. Ambres. Indeed, it's possible Grace is even exerting some control over Dr. Ambres on a subconscious level.
So far as The Flash #39 goes, its premise is fairly straightforward. When Barry attempts to make amends with Gorilla Grodd, the telepathic gorilla attacks Central City and uncovers something that changes "everything Barry thought he knew." Likewise, The CW series has plans to bring Grodd back for an epic fight with King Shark.
"We've been trying to do that every year and we just run out of money, but I think we've figured out a way to do it this year," showrunner Todd Helbing told CBR. "We're breaking that story right now, actually. And as long as I don't totally shank the budget, we should be good."
Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanaugh, Jesse L. Martin, Danielle Nicolet, Hartley Sawyer and Jessica Parker Kennedy.
