Cody was unhappy about veteran Paul Abrahamian returning to the game. He managed to win the Safety Competition on day 1, granting him immunity from the first eviction. Week 1 he had won the Head of Household competition and nominated Megan Lowder and Jillian Parker, having Megan as his target then. He founded the huge showmance alliance and started to run the house. After Megan suffered a PTSD attack and walked from the house, Cody then nominated Alex Ow, as he was pressured by his allies to do so. Not wanting to see her leave, Cody threw the PoV to Alex, causing a stir with his allies. After attempting to backdoor Paul, Paul showed off his Pendant of Protection, a gift temptation guaranteeing him three weeks of safety. Cody then turned his back on another alliance member, Christmas Abbott, nominating her for her close affiliation with Paul. Cody's HOH failed when Paul flipped Kevin Schlehuber and Josh Martinez against him by evicting Jillian. For a short time, Cody tried to stay in the house. After Paul made him the replacement nominee at the week 2 PoV ceremony, Cody knew he was going home, and started planting a seed in Paul's mind that would make him go after two of his ex-allies, Dominique Cooper and Mark Jansen, instead of targeting his showmance partner Jessica Graf. Cody was evicted in a 7-3-0 vote.
Cody had successfully won the Battle Back Competition against the other three evictees and had also defeated House Challenger Paul, who the house sent to keep the Battleback winner from entering the house. Since then, Cody let Jessica do a majority of the talking and reasoning. In week 6, Cody won the Temptation Competition which granted him immunity for the week, though a large blowup with Josh Martinez resulted in his showmance Jessica Graf getting evicted. Cody then formed a close friendship with Kevin. When Alex won the HOH the following week, the house had the plan to backdoor him, which successfully happened. He was evicted during the first half of the first Double Eviction in a unanimous 7-0-0 vote, placing 11th and becoming the first member of the Jury.
On finale night, he won America's Favorite Houseguest.
