A huge decision has to be made in the upcoming episode of "The 100" season 4.

Titled "The Other Side," next week's episode will see Clarke (Eliza Taylor) in yet another tough situation. She is forced to face the consequences of her choice to take the bunker to Skaikru. It remains to be seen how Octavia (Marie Avgeropoulos) will react once she finds out that Clarke and Jaha (Isaiah Washington) betrayed the agreement and Bellamy (Bob Morley) had something to do with it.

In the latest episode "Die All, Die Merrily," many warriors died after the bloody conclave, including Ilian (Chai Hansen), Luna (Nadia Hilker) and Roan (Zach McGowan). Fortunately, Octavia did not suffer the same fate due to her impressive fighting skills. She was given the power to give the bunker to Skaikru, but she revealed that she was fighting for all people. She decided to share the bunker with all the clans. Their happy moment was cut short when Octavia, Kane (Henry Ian Cusick), and Indra (Adina Porter) discovered that Clarke and Jaha had actually stolen the bunker before the conclave.

Avgeropoulos recently caught up with TV Guide and she teased that major changes are in store for her character. After being betrayed by Clarke and Jaha, Octavia and her friends will try a different approach to survive the apocalypse. She also teased that fans should look forward to a possible altercation when Octavia meets Clarke and Jaha again.

"Their next challenge is trying to get the bunker open so they can have a chance at survival, but once that bunker door is open, Octavia was victorious," the actress said. "She's the champion and she's now the leader, so she gets to make the call. So it'll be an interesting altercation when she does face Clarke and Jaha and they standoff against one another [after] this ultimate betrayal."

The fourth season of "The 100" airs every Wednesday at 9 p.m. EDT on The CW.
