Watch the new "Shadows" trailer below for The Flash Season 5, which features Nora Allen in action and teases the villain.
"This man is hiding in the shadows," Tom Cavanagh says in a voice over seemingly referring to the show's villain this season.
"You guys beat him. At least you were supposed to," Nora Allen said.
This past San Diego Com-Con revealed that actor Chris Klein has been cast as the super-villain Cicada, a grizzled, blue-collar everyman whose family has been torn apart by metahumans, Cicada now seeks to exterminate the epidemic â€” one metahuman at a time.
In the comics, Cicada was a mysterious cult leader who aimed to murder anybody that The Flash had ever saved, using trademark lightning bolt daggers.
Regaring Nora Allen, the TV series pays homage to the dead mother of Barry, who shares the same name instead of using the name from the comics with Dawn.
"She comes back for a specific reason, not only to see her parents and meet everybody on the team, which you saw all throughout the season â€” thereâ€™s four specific times that she came back, and youâ€™re gonna learn about why she chose those four times and how theyâ€™re gonna play into not only the mistake that she made, but the consequences for somebody like her, a speedster traveling from the future to the past, and what that means for Barry and the team," executive producer Todd Helbing said in a previous interview.
"Yeah, she comes from 30 years in the future, so 30 years from now, a lot has happened," Helbing said. "Sheâ€™s privy to information that nobody else is, so her experience in the future is certainly different than where everybody is now. A lot of next season too, youâ€™re gonna see this relationship between Barry and Iris and Nora, so we just wanted to give the audience a little glimmer into what her reaction is to everybody. If you go back and watch all of the ways that she interacted with everybody, you can get a nice little sense of what her relationship is with everybody in the future."
New episodes of The Flash premiere Tuesday, October 9 at 8/7c on The CW starring Grant Gustin and Candice Patton.
