Octavia (Marie Avgeropoulos) never set out to be a leader on The 100, but she'll be forced to step up when things in the bunker start to go very, very wrong.

Although they're perfectly safe from Praimfaya, the people of Wonkru soon realize there's another impending crisis that threatens everything they've worked for, sending the bunker into complete chaos. "They're at each other's throats pretty quickly and she needs to stop that from happening, otherwise they'll just kill themselves off," creator Jason Rothenberg tells TV Guide.

Fans have already gotten a few glimpses of Octavia fighting back the deadly uprising in trailers, but we can assure you that those looks are only the beginning of the horror to come. Octavia will be forced to take drastic measures to keep her people - who in her mind are the only remaining people - safe. So is there such thing as going "too far" if it means saving humanity? In Octavia's eyes, probably not.

The 100 returns Tuesday, April 24 at 10/9c on The CW.
