The 100 Season 7: Everything We Know

With the final season premiere of The 100 just a few days away — the fun begins Wednesday, May 20 at 8/7c on The CW — TVLine is bracing for the impending madness by taking stock of everything we already know about Season 7.

Scroll down for extremely mild spoilers, courtesy of the explosive trailer, casting breakdowns and our latest interview with showrunner Jason Rothenberg.

WHO'S BACK?

Despite the major losses of Season 6, most of the main cast lived to fight another day. The same, however, cannot be said for all of their original haircuts.

All of the clues laid out before us suggest that the Anomaly is capable of transporting people through time and space, though the specifics of how it works remain... unspecified. When Clarke asks where it leads, Raven simply replies, "Everywhere."

WHO'S NEW?

Shelby Flannery, the actress introduced in the sixth season finale as a grown-up version of Hope Diyoza, has been promoted to series regular. (Don't worry, though, it looks like we'll also get to enjoy some time with Baby Hope.)

"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," Rothenberg tells us.

Alaina Huffman (Supernatural) will recur as Nikki, "one of the newly-awakened Eligius IV convicts. Nikki is a bank robber and spree-killer who is both unpredictable and fierce. She will take on an unexpected leadership role, advocating for her people in the complicated new world of Sanctum."

Chad Rook (Siren) will also recur as Hatch, a charming Eligius convict who is determined to forge a better life for those he loves.

WHAT IS IT ABOUT?

The focus of The 100's final season will be the mystery of the Anomaly, showrunner Jason Rothenberg confirms to TVLine, promising, "We're going to be all up in that thing."

After finally taking a moment to properly say goodbye to her mother, Clarke attempts to rally the people of Sanctum for survival. Of course, it's anyone's guess how her course will shift when a mysterious stranger tells Clarke that she's "the key to winning the last war mankind will ever wage."

Meanwhile, Gaia will remain a close confidante of Clarke's, fielding concerns like, "I used to think fighting is what we do. Now, I wonder that fighting is what we are."

And if you thought JR Bourne's character was unhinged before, just wait until you see what the final season has in store for him. I'm just saying, it's not a great sign when you go from talking about peace to screaming "I need death!" in the span of a single trailer. (And by the looks of that gun Clarke is pointing at his head, she just might have to oblige.)

As evidenced in the trailer, all these years of battling have really brought Indra's dry sense of humor. ("New world, same problems.")

The Blake siblings' ever-fluctuating dynamic seems to be swinging back in a positive direction this season. "I can't let you die to save me," Octavia appears to tell Bellamy the trailer.

And it should come as no surprise that Monty and Harper's son is trying to avoid conflict at all cost. "The answer to all this violence isn't just more violence," Jordan says in the trailer.

That episode, titled "Anaconda," will introduce us to at least three new characters:

Iola Evans (Carnival Row) plays Callie, a "whip-smart and passionate with a rebellious streak to boot." She's big into fighting for the causes in which she believes, "but when the apocalypse devastates the world she had been working so hard to save, Callie must find a new purpose — and future — for all that remains of humanity."

Adain Bradley (The Bold and the Beautiful) plays Callie's Brother Reese. He has always been competitive with her, "but when the opportunity to finally prove his worth comes with an incredible cost, Reese must figure out what lines he is willing to cross to finally come out on top."

And Leo Howard (Why Women Kill) plays August, a "rebellious and passionate musician." He's also a radical environmentalist who believes in protecting the planet "by any means necessary." For August, the apocalypse is particularly depressing, as he's left to "figure out how to go on when everything he had been fighting for is gone."

WHAT'S NEXT?

One Season 7 epsode, a backdoor pilot for a proposed spinoff, will take us back 97 years before the events of Season 1. The prequel would follow "a band of survivors on the ground as they learn to cope in a dangerous world while fighting to create a new and better society from the ashes of what came before."
