At the end of season four, Barry and Iris found out they have a daughter in the future. How would they know? It's that same daughter that comes back to their current time period with Barry's power set. So, that alone seems like one of the biggest things season five will have to dig into.
Here's a new trailer showcasing what season five has to offer...
“We always like to introduce characters and sort of highlight areas that come from the comics but we don’t want to be beholden exactly to them so we can change the stories as we see fit and tell it for a television show,” showrunner Todd Helbing said regarding Nora and Cicada.
Cicada appears to be the big bad of this new season, so we'll see what new challenges he can present Barry and his team. The Flash runs back to television, Tuesday, October 9th (8PM EST) on the CW.
