The 100 Season 4 did the unthinkable: It sent a group back into space with the hopes of saving themselves as Praimfaya brought hell on earth. 

With Octavia and her team under the ground inside a bunker, Clarke was left to die after making the ultimate sacrifice. However, having nightblood inside her saved her life. 

We left the show with a striking visual as a new ship appeared on the ground just as Clarke revealed to a young nightblood that it was not her people. 

The cast and EPs of the CW series — Eliza Taylor, Bob Morley, Marie Avgeropoulos, Lindsey Morgan, Richard Harmon, Chris Larkin, Dean White and Jason Rothenberg — reunited Friday for the show’s San Diego Comic-Con panel, where they talked about what to expect when the groundbreaking drama returns for Season 5. 

Showrunner Jason Rothenberg was quick off the mark to explain the origins of the prison ship. 

“The prison ship [from the season finale] is from Earth,” Rothenberg revealed.

“They’re from before the first apocalypse. They were in hyper-sleep for 100 years. They’ve come back to this planet that they don’t recognize. All that’s left is this Garden of Eden that Clarke’s been living in with her daughter.”

Yes, he really referred to the young girl as Clarke's daughter. It sounds like they've struck up a mother-daughter bond in the time they've spent together. 

Like most actors working on teen dramas, Eliza Taylor is stoked about the prospect of playing an older and wiser version of Clarke. 

“It’s nice to be playing someone a little closer to my age,” Taylor said of the time jump.

“It’ll be exciting to see her as a 24-year-old woman who’s been through so much, and is now taking on this maternal role.”

When we left off, Octavia and her people were yet to emerge from the underground bunker that housed 1200 people across the clans. 

“Octavia doesn’t have a clue what she’s doing,” Avgeropoulos declared, “but she doesn’t want to set off chaos with 1,200 people in the bunker. … You’ll see what her plan is to keep the peace and how she reprimands others in her own special way.”

At least we now know that Octavia is still alive, but it's difficult to imagine every single person surviving the time jump. There was a lot of unrest, and it's likely there will have been fights for power. 

With a bunch of characters in space, the talk turned to how they will change following the time jump. 

“All of us have to change up [in space],” Harmon said. “It’s freeing in a lot of ways. Over six years, a lot of therapy can happen. Murphy’s definitely going to change.”

The cast even questioned whether some of the relationships could have changed. 

“Harper is Monty’s main lifeline at the current moment,” Larkin said.

“He owes her his life. She chose him. I don’t know if they’re still together. … Maybe Monty and Murphy are together. It’s been six years!”

Finally, new series regular Tasya Teles opened up about her thoughts on Echo integrating with the core characters. 

“I think about it a lot. Who will she become friends with? … I was thinking she’d get close to Raven for some reason. They’re girls who get things done. I see those two having an alliance.”
