Kat was one of the ten returning houseguests to enter the Big Brother Orre house. She started out by lying low and creating bonds with Jose P from her original season and Sammy. The three quickly became a trio early on in the game. By popping up on house calls and talking actively in the house chat, Kat was able to stay under the radar and out of the drama for the first few weeks. It wasn't until wild card Lynn won the HoH competition Week 5 that Kat finally hit the block next to fellow Alola houseguest Jose P. Fortunately for them, they were next to house target Ricky and they both survived the eviction. The following week Kat was put in a swing vote position where she decided to go against the house, align with the outsiders and evict Dennis over Randy. Though Randy still left, she was now in with Autumn, Jose P and Ali M. The following week when Kat was a final nominee a message was sent to the house chat before eviction saying: be careful who you evict this week. Hoping that the evicted houseguest would gain some sort of useful power, Kat asked to be evicted and did in fact get a power. For Week 8 RAT Week, she was able to pair up the houseguests and participate alongside the pre-juror of her choice for re-entry. She chose Randy and the two of them competed in the Race Against Time together. When they only won one leg of the competition, Kat decided to give Randy her slot back in the game, making her the final pre-juror for two seasons in a row.
