Season 2 of DC’s Legends of Tomorrow ended with the titular Legends realizing that, in their attempts to fix time, they actually screwed it up even more, which was clear because there were dinosaurs stomping around Los Angeles in 2017. It turns out that’s only the tip of the iceberg.

At Entertainment Weekly‘s Comic-Con studio, showrunner Phil Klemmer said that trying to repair the stream (again) in season 3 is “at least a season-long endeavor.” “Obviously there’s a clear and present danger of dinosaurs going around Los Angles, but then, we’re gonna realize that was just sort of the tip of the iceberg and that it’s more than just these sort of one-off anachronisms, that it’s all part of a giant Big Bad and a consortium of some horrible bad guys that we can’t talk about,” he continued.

Along the way, the team will gain a new member: Zari Adrianna Tomaz, a hacktivist played by Tala Ashe. Given the fact that she’s from the future, she’s seen the results of the Legends’ actions and has some thoughts.

“It’s going to be interesting for her to share sort of what her impression of the future is with the Legends in 2017 because she’s seen some of the fallout from 2017,” said Ashe.

Klemmer went on to reveal who she will be paired with. “The most obvious is with Brandon [Routh]’s character Ray, because he’s obviously a futurist, an inventor, a guy who has this boundless optimism about the future being better and brighter and all these things,” he said. “She comes and says, ‘Oh great, all those things you were trying to do to the world, all your inventions, they didn’t add up to anything.’ … It challenges our team to think about what they’re doing, which is, ‘Are we just fixing history or are we improving the future?'”
