Two tribes will merge into one in the next episode of Survivor: Cagayan, and there are bound to be conflicts.

Survivor: Cagayan: Who Becomes First Member Of Season 28 Jury?

Episode 6 of Survivor: Cagayan is titled Head of the Snake and features the six members of the Aparri tribe merging together with Solana's five. While Aparri has a clear advantage as far as numbers, there is always the possibility of members switching to the other side.

This seems like a distinct possibility in this episode based on the promos. The latest preview for the episode features both Kass McQuillen and Sarah Lacina considering switching over from the Aparri tribe to the Solana tribe. The promo also teases that there is a shocking elimination at the end of the episode, indicating that a member of the majority might be the one going home.
