The seventh and final season of The CW's The 100 has added Shelby Flannery as a series regular. Flannery appeared as a grown-up Hope Diyoza in the Season 6 finale.

“She’s awesome,” showrunner Jason Rothenberg told TVLine. “I’m fairly certain we were her first professional job. She’s just out of drama school, so she’s really new, and I’m excited to see what she can do. That scene was just the tip of the iceberg. She’s going to be a big part of the story moving forward. I have a good feeling about her as an actress and a person. We’ve got her in serious fight training right now.”

Season 7 of the fan-favorite CW series will follow-up on the Anomaly that resulted in the aging-up of Flannery's Hope.

“That reveal is obviously mind-blowing,” Rothenberg said. “The fact that Hope is now in her early twenties, when three days ago she was a fetus, does begin to imply some things about the Anomaly and about where we’re going.”
