A member of the all-"white collar" Masaya tribe, she was chosen by Joaquin Souberbielle to assist him in making a decision on behalf of the tribe. Shortly after, So and Joaquin learned that their choice was between a big bag of beans or a Hidden Immunity Idol clue. Although So feared picking to deceive would put a target on her back, the two still chose the Hidden Immunity Idol clue, and became allies. The two then fabricated a lie about a neutral option, which none of their tribemates believed. So and Joaquin were never successful in finding the idol however, as Carolyn Rivera already found it after seeing them looking around camp.
After losing the first Immunity Challenge on Day 3, So began targeting Carolyn because she was the oldest woman on the tribe and accused her for not volunteering in crucial parts of the challenge. Despite her pleas, So's initial mistake came back to haunt her, eliminating her in a 4-2 vote.
