Big Brother: Rivals and Redemption:
An accomplished YouTube host and big fan of the show, Sophia was selected by Brock Knutson to join his team during the Day 1 hosueguest draft. Once inside the house, Sophia gathered other female fans, Makaya Knight and Michelle Blausk, to create a closely-knit, three-person girls alliance, citing how she wanted to rally the "Girl Power". Sophia also became close to fellow Team Brock member Kat Adle, bringing Kat in as a potential number for her forming girls alliance. With a strategic position established, Sophia joined the majority of the house in evicting Jason Garland at the first live eviction of the summer later that week.
However, after team captain Brock won the next Head of Hosuehold competition and decided to target her allies, particularly Michelle, Sophia began to butt heads strategically with Brock and his allies, particularly when Sophia attempted to flip the vote to save Michelle, making her a target to the "Square of Strength" alliance. Ultimately, Sophia was unsuccessful at turning the tide, and Michelle was evicted by a vote of 9 to 1, with Sophia's vote being the only vote to keep Michelle in the house. During the following week, under Felice Marroquín's HOH reign, Sophia was nominated against Felice's target Yissendau Martins as a pawn. Despite Felice's and several others' desires to see Yissendau evicted, the Square of Strength and its allies ultimately voted together to send Sophia home by a vote of 6 to 3.
