DAY 13

*POV PLAYER PICKS*

*Siobhan runs out of the diary room with the box of chips*

Siobhan: "Hey everybody! It is time to pick players for the veto competition!"

*Everyone gathers in the living room and sits on the couches while Summer and Catarina sit in the nominations chairs*

Siobhan: "Myself, the two nominees and three other houseguests picked by random draw will compete in the veto competition! As HOH I will draw first."

*Siobhan reached in and pulls out a chip*

Siobhan: "Gavin!"

DR: Siobhan: "I'm SO happy I picked Gavin! Gavin is a strong player and he will do almost anything to win!"

*Catarina then reaches in and pulls a chip*

Catarina: "Candy!"

DR: Catarina: "YAS, I PICKED MY BFF! I am so so so glad I picked Candy because I know 100000% for sure she would use the power of veto on me!"

*Summer then reaches in and pulls a chip*

Summer: "Sergio!"

DR: Summer: "UGH! Why did I have to pick Siobhan's boo? This sucks! But maybe I can somehow persuade him to use it on me? Use my looks." *winks*

Siobhan "As HOH, I need to choose a host for the veto competition and I choose Zoe!"

Zoe: "Yay! Thank you so much, Siobhan!"

Siobhan: "Big Brother will inform us when it is time to play! Good luck to everybody!"

*In the Pantry*

*Siobhan and Sergio walk into the pantry. Siobhan is ignoring Sergio and Sergio is confused on why*

Sergio: *whispers* "What's wrong, babe? Why are you mad at me?"

Siobhan: *whispers* "Because! You keep staring at Summer! I don't freaking like that at all! You are staring at her like you are attracted to her or something!"

Sergio: *whispers* "I'm not attracted to her, babe."

*Siobhan rolls her eyes*

Siobhan: *whispers* "Whatever. Just stop looking at her like you do. I'm your damn girlfriend. Summer has a showmance with Akira! I don't want Akira to target you over this nonsense if he sees you do it! Just stop!" 

Sergio: *whispers* "You are making something so small into something that's a big ass deal. Just chill, Siobhan. Focus on being HOH and not what I'm doing."

Siobhan: *whispers* "I'm focusing on the both of us? You want that money prize?"

Sergio: *whispers* "Yeah, I want the first prize. And I want the big prize too!"

Siobhan: *whispers* "Then stop acting like this and focus on OUR game! It's OUR game until the secret couple thing is over! You need to worry about the both of us!"

*Sergio huffs and leaves the pantry*

*In the Lounge*

*Akira and Summer walk into the lounge*

*Summer frowns while Akira rubs her cheeks softly. Akira then kisses Summer and hugs her tightly*

Akira: *whispers* "Everything will be okay, Summer. I promise you that you won't go home this week. I will make sure of that."

Summer: *whispers* "I hope so. This really really sucks. I hate fo fight against my friend but I wanna in this game."

Akira: *whispers* "I know it sucks. But you need to focus on yourself and your game. You know?"

*Summer nods and hugs Akira tightly*

Akira: *whispers* "You got this."

*Akira kisses Summer's cheek*

*VETO COMPETITION: "NOW YOU SEA IT" (CBBUSA) HOST: ZOE*

PLAYERS: Siobhan, Catarina, Summer, Gavin, Sergio, & Candy.

Two at a time, you will face off at the podium. There, you will see a billboard advertising a new star-studded cruise. For each billboard, Bree will ask you a question containing a number. The answer to each question will be either "more", "exactly", or "less". If you are the first to buzz in with the correct answer, you stay in the game, and your opponent is eliminated. You will then choose the next two houseguests to face off. If you answer incorrectly, you will be eliminated, and your opponent will stay in the game. If no one buzzes in, you will both be eliminated unless you are the final two in the competition. The last houseguest standing will win the Power of Veto!

DR: Catarina: "I desperately need this veto right now! I need it so freaking bad! I'm hoping I can win and keep myself safe!"

DR: Gavin: "I will do anything and everything to win this veto and keep Siobhan's nominations the same! We need to even the numbers out and make this fair!"

DR: Sergio: "I don't like Siobhan has been acting! Maybe if I win the veto, this little strain we are dealing with will heal."

*After twenty five minutes of playing*

GAVIN HAS WON THE POWER OF VETO

Zoe: "Congratulations, Gavin! You have won the Power of Veto!"

DR: Gavin: "Look who won the veto! Me! Now it's time to evict one of these girls to even this up!"

*AFTER VETO COMPETITION*

*In the Bathroom*

*Akira and Summer are in the shower together and are making out*

*Travis walks in and is terrified at the sight of Akira and Summer*

*Summer opens the shower and poses her naked for Travis and Travis stares at her*

*Mitchell walks to the bathroom sees Travis staring at a naked Summer and Akira*

*In the Tie Dye room*

*Mitchell walks into room where Gavin and Jameson are sitting on a bed*

Mitchell: *whispers* "Summer was posing naked and Travis was just staring at her! I don't know if he liked it or not!"

Gavin: *whispers* "Staring at her? What the hell! I am going to kick his ass!"

*Jameson holds Gavin's back to calm him down*

Jameson: *whispers* "Gavin! Shhh! Summer is such a damn slut! Did Akira mind that she was flashing herself at Travis?"

Mitchell: *whispers* "He didn't seem to mind honestly! They are an odd couple."

Gavin: *whispers* "I'm so pissed off right now!"

*Jameson rubs Gavin's back*

Mitchell: *whispers* "Well, I'm gonna head out of here and go swimming with Miko. See you guys later."

Jameson: *whispers* "See ya! Thank you for letting us know about Travis."

Gavin: *whispers* "Thank you, Mitchell."

Mitchell: *whispers* "You're welcome! See you two later!"

*Mitchell leaves the room and then Travis walks into the room a few minutes later*

Jameson: *whispers* "Travis, we need to talk to you."

Travis: *whispers* "Sure, what's up boys?"

Gavin: *whispers* "Why were you staring at Summer? Huh? You think she's hot or something?"

Travis: *whispers* "What? I don't think Summer is attractive at all, Gavin! I love you both!"

Jameson: *whispers* "Well, why did somebody tell us you were looking at Summer naked?"

*Travis sighs and covers his face with his hands*

Travis: *whispers* "She and Akira were taking a shower and Summer playfully flashed herself. And I don't know why I looked! I panicked!"

Gavin: *whispers* "I can't freaking believe this!"

*Travis sighs again*

*In the HOH room*

*Gavin and Siobhan are sitting together on the HOH bed*

Gavin: *whispers* "Since I won the power of veto, I wanna know what you want me to do."

Siobhan: *whispers* "I want them both gone but that's not going to happen."

*Siobhan and Gavin chuckle*

Gavin: *whispers* "A double eviction right now would be iconic but those don't happen until jury starts."

Siobhan: "I really really want Summer gone because she is constantly flirting with Sergio and others but I need to keep my head in the game. Catarina is a good person to evict honestly because she's more of a drama queen, a floater and she doesn't deserve to be here to be honest."

Gavin: *whispers* "Summer was flirting with Travis earlier and I'm like UM, not today sweety! And well, I'll supportive your choice no matter what! I won't use the veto!"

Siobhan: *whispers* "Sounds good to me! You did great at the veto comp!"

Gavin: *whispers* "Thanks babe! Well, I'll see you later!"

Siobhan: *whispers* "See you later!"

DAY 14

*VETO MEETING*

Gavin: "Hey everybody, it is time for the veto meeting."

*Everybody sits in the living room. Catarina and Summer sit in the nominations chairs. Gavin is standing in front of everybody*

Gavin: "This is the veto meeting. Catarina, Summer, you've both been nominated for eviction. But I have the power to veto one of the nominations. I want to give both nominees a chance to tell me why you think I should use the power of veto on you. Catarina you go first."

Catarina: "Gavin, congratulations on winning the power of veto! I want you to know how badly I need this prize. I really need a new house. I need money for my savings account and for my future life. I will do anything to stay in this game. Please consider using the power of veto on me. Thank you."

Gavin: "Thank you, Catarina. Summer, it is now your turn to speak."

Summer: "I just wanna say that whatever you wanna do Gavin your choice and I will do anything to stay in this house and this game. I'm not here to play around and kiss ass with all of you. I'm here to win it all. Thank you."

Gavin: "Thank you Summer for speaking."

Gavin: I have decided to not use the power of veto. I wanna respect Siobhan's nominations and to keep them the same this week. This veto meeting is adjourned."

*Gavin shuts the veto box*

DR: Catarina: "I am going to campaign hard and remain in this game! Ain't nobody going to stop me!"

DR: Summer: "I hate to campaign against my best friend. This really sucks. But I will do anything to stay and ultimately win!"

DR: Siobhan: "This week is going by SO perfectly! Now, I need to decide who I want to be evict this week. Both of them have pros and cons so I need to make sure it's a perfect decision."
