The kids feel guilty and sad about the ones who have died, and this pushes them to drift apart and blame one another. Kyung-jun, the class bully, continues to pick on others and use them to test the rules of the game. Meanwhile, Class President Jun-hee has an idea to refuse to vote for anyone in the game that night.

As Jun-hee's plans to refuse to vote backfires, a bloodbath sweeps the assembly hall. The remaining kids are as divided as ever in the aftermath of losing so many kids in one night. Meanwhile, Yoon-seo is suspicious of the visions she keeps having. She decides to scope out the mysterious tunnel that she found.

Woo-ram, the one with the highest votes so far, is about to lose his mind out of fear, and Kyung-jun, the one with the second highest votes, tries to take him down before midnight. Meanwhile, Yoon-seo is stuck on the second floor and finds a photo of the girl she saw in her dream.
