Big Brother's houseguests evicted Kaitlyn Herman from the house instead of Angie "Rockstar" Lantry during Thursday night's live Season 20 episode on CBS.

Kaitlyn, a 24-year-old life coach from Plainview, NY, who currently resides in Encino, CA, was sent packing on Day 37 through a 9-1 vote in which JC Mounduix was the only player who voted to evict Rockstar.

Kaitlyn had a chance to win a spot back in the game thanks to Sam Bledsoe's "Bonus Life" power app, but she failed to complete a puzzle in time, and so her eviction stands.

"I can live with the fact that I just didn't [solve the puzzle]... It was for the highest good. There's someone out here that needs me more than in there, and I'm so proud of myself. [But] I'm so sad," Kaitlyn said after discovering all of her allies had turned against her and voted her out.

In a flashback to Day 34 after the Veto Meeting, Kaitlyn was extremely upset and disappointed Faysal Shafaat decided to save Haleigh Broucher instead.

Kaitlyn said Faysal's betrayal changed the way she looked at him. She was certain she was going home now, and she thought Faysal made her look like an idiot.

"I really thought he was my best friend... it hurts my heart so much," Kaitlyn cried to the cameras.

Faysal admitted to Kaitlyn her blindside against Chris "Swaggy C" Williams played a role in his choice, but she didn't want to hear it and asked him to leave her alone.

Tyler Crispen was worried about the upcoming eviction because he told Faysal afterwards that Kaitlyn was his closest ally. He was also in her ear all the time making moves, and so he knew it would be good for his game if she stayed.

Tyler therefore told Kaitlyn to become close with JC and convince him that the two of them could backdoor Faysal the following week. Kaitlyn obliged, because she needed every vote she could get. Even Haleigh questioned whether she should just vote Kaitlyn out since she's a strong competitor.

JC then talked to Angela Rummans and Brett Robinson about how Kaitlyn was unpredictable and a good competitor and Rockstar was a more loyal person, so maybe they should take Kaitlyn out when they have the chance.

While JC was sold on voting Kaitlyn out, Angela and Brett both planned on voting for Rockstar because she was gunning for the both of them. Tyler hoped JC would come around to their thinking.

Meanwhile, Kaitlyn was still crying about the Power of Veto. Faysal considered her a best friend, but he was beginning to view her as annoying since she'd lose herself in these "emotional swings" and try to make him feel guilty.

Haleigh said she had four votes to keep Rockstar safe -- Faysal, herself, Bayleigh Dayton and Scottie Salton. Haleigh said in a confessional her alliance needed Rockstar in order to survive this game and forward. They only needed two more votes, as a result, to send Kaitlyn packing.

Rockstar felt she had her friends behind her, and so she began campaigning to stay. She even fed into Brett's ego a little bit in attempt to reconcile with him.

In a shocking twist, Tyler spoke to Brett and Angela about targeting Kaitlyn, saying now would be a great time to take her out. Tyler was admittedly "flippy floppy" over the situation, and Brett agreed with the logic, calling her "a ticking time bomb."

"She's actually good at the game," Brett said of Kaitlyn. "Rockstar sucks at the game... She's not a threat. Her social game sucks ass. Her physical game sucks even worse ass."

Angela, however, wondered if it would be smart to keep a bigger threat than Brett in the house, like Kaitlyn. The group also agreed Rockstar wouldn't have a good chance to win her way back into the game.

Tyler thought if he voted against Kaitlyn and she re-entered the house, he "would be screwed." But if he voted for Kaitlyn to stay, the whole house might be mad at him. Tyler figured he was going to be screwed no matter what he chose to do.

When it became time for the live eviction, Kaitlyn was ousted from the Big Brother house through a vote of 9-1. JC was the only houseguest who voted to evict Rockstar.

Just as Kaitlyn was about to leave the house, Big Brother host Julie Chen announced she would be given a chance to return to the game thanks to Sam's "Bonus Life" power app.

Kaitlyn was required to break apart a lifesize puzzle of herself and then put it back together within two-and-a-half minutes. If she could complete the puzzle in time, she would win a spot back in the house. Kaitlyn was close, but she failed to make her puzzle stand up.

Kaitlyn didn't know what to do but cry, and she left the house without hugging or saying goodbye to anyone.
