With San Diego Comic-Con in full swing, we’ve been receiving a ton of updates on films, comic book series, and television shows. That last category includes one of our favorites: The 100. After the jaw-dropping season three finale, we’ve (as I’m sure you’ve) been anticipating news on the upcoming season. While we don’t know too much about what’s on the way, we did get a sneak peek of a potential scene, and a tease of what’s to come during the show’s SDCC panel. It was also revealed that Zach McGowan, who joined the show last season to play Roan, would be a series regular in season four.

“The Earth strikes back in season four—it is an unbeatable foe,” creator Jason Rothenberg teased regarding next season. “It quickly becomes about not how to stop it, because stopping it is not possible, but about: How do we survive? There aren’t enough lifeboats, so who gets to choose who lives?”

With total nuclear destruction on the way, getting her people to safety is something Clarke (Eliza Taylor) will have to deal with. In the exclusive clip shown off during the panel, we hear Clarke’s ominous narration: “Our enemy isn’t something that can be fought. It can’t be reasoned with. It can’t be killed. When all is lost, can hope survive? can we survive? After everything we’ve done, do we deserve to?”

After losing major characters like Lexa, Lincoln, and Pike last season, facing the impending apocalypse will be difficult for everyone. Octavia, for instance, will be traveling down a much darker road, channeling her inner assassin. She explained, “Octavia will take a really dark turn. She’s going to do what she does best, which is killing people. She really found her home within herself in becoming a warrior, and that’s thanks to Lincoln and Indra.”

The big news, however, was that Zach McGowan (Roan) has been bumped up to series regular. As a result, fans should expect the character to play an even bigger role this season. Also, Rothenberg revealed that Adina Porter (Indra) will be returning for several episodes.

The 100 is set to return next year on the CW.
