So when Tyler -- whom Kaitlyn has secretly been working with -- won the Power of Veto competition and removed Scottie -- known to be Swaggy C's "right-hand man" -- from the block, Kaitlyn shocked the house by nominating Swaggy C in his place.
The big move was especially shocking because Kaitlyn's original alliance would lose a member and a number because of this move.
The Big Brother episode began with both Winston and Scottie being paranoid and skeptical about their nominations. Winston therefore pointed out he needed to win the Power of Veto and save himself.
Winston's pal Brett Robinson also hoped to win so he could protect his ally.
In order to successfully backdoor Swaggy C, Kaitlyn intended to convince the FOUTTE alliance she was with them "100 percent."
The Power of Veto competition, based on Big Brother's new "Houseguests Only" dating app, required the players to use clues given on former Big Brother houseguests' dating profiles to place their lifesize cardboard cutouts in the correct date locations.
The clues had to do with each former houseguest's likes and dislikes.
For example, Cody Calafiore loves Italian food, but since he doesn't like wearing shirts, his date would probably meet him at the park rather than an Italian restaurant.
The players in the Veto competition completed the challenge one at a time, and the person to place the former houseguests in their correct corresponding restaurant, coffee shop or destination in the fastest time would be named the winner.
Rachel completed the competition with a time of five minutes and 49 seconds. Scottie finished the competition in 18 minutes and 20 seconds. Winston finished the job in 20 minutes.
Tyler completed the task in five minutes and 29 seconds. Faysal walked away with a time of six minutes and 22 seconds. And finally, Kaitlyn's time was 13 minutes and 12 seconds.
As a result, Tyler won the Power of Veto. He said he was "stoked," but at the same time, he didn't want his fellow competitors to know he was "running things."
Kaitlyn was excited about pulling off a huge move soon, but with that also came nervousness.
Tyler decided to use the Veto on Scottie given he's Swaggy C's "right-hand man," but when he spoke to Kaitlyn about his goal, she was having second thoughts and questioning whether she should back out of the initial plan. Tyler comforted Kaitlyn and insisted the move to take out Swaggy C had purpose.
Kaitlyn told Faysal she'd probably nominate Angela Rummans for eviction if Tyler used the veto, but she was lying to his face and felt really guilty. Kaitlyn, in fact, cried about the idea of potentially losing her best guy friend in this game.
Kaitlyn ultimately chose to share her plan to backdoor Swaggy C with her friend Haleigh Broucher, who pretended to understand and be on her side. But Haleigh's stomach dropped and she was scared, because Swaggy C was a number from her alliance and her side of the house.
Haleigh then confided in Angie "Rockstar" Lantry, who promised not to tell anyone about Swaggy C being the target. Faysal told Rockstar that Angela was Kaitlyn's backdoor target, but Rockstar knew better and tried her absolute hardest to keep her mouth shut.
Before the Veto Meeting, Kaitlyn told Faysal that she hoped they could remain friends after she goes through with a big move, and Faysal immediately knew whom she was talking about. Faysal was quiet and didn't say much, but he was clearly upset.
At the Veto meeting, Tyler opted to use the Power of Veto on Scottie, and then Kaitlyn named Swaggy C the replacement nominee.
When Kaitlyn made the announcement, she apologized to those who would be angry at her, saying she'd never be promised this position again and didn't want to fly under the radar.
Tyler was thrilled the stars had aligned and it was time to "show [Swaggy C]" the door, but Faysal was "absolutely pissed" she had concocted this "massive plan" behind his back.
And Bayleigh Dayton was upset, saying her side of the house was going to lose all trust in Kaitlyn.
Meanwhile, Kaitlyn was proud of herself for sticking up for herself and staying true to herself, but Swaggy C was ready to give everyone hell.
