Big Brother 4

Big Brother 4 is the fourth season of Big Brother. It features 16 houseguests, and began airing on 4 September 2023. 
The season was won by Yoichi Yukimura, winning 6-3 against Cole Xo.
==Background==
The season began on 4 September 2023, almost 2 years since Big Brother 3 aired. It aired simultaneously to The Challenge: Battle of the Simulators.
==Twists==
*Week 1 Immunity: The first HOH competition was played in 3 stages, the first 2 featuring 8 houseguests of each gender. Parts 1 and 2 had three 'winners', who would progress to part 3 and also win immunity for the week. The 5 houseguests winning immunity were Hinata Hoshido, Jace Whatever, Luke Kys-Fart, Sabrina Carpenter and Taylor Swift - with Ailee Lee winning HOH.
*Guardian Angel: After getting evicted, the first four evictees had the ability to give 3 houseguests a week of immunity once they had left the house. Karla Bazzari chose to give this to Yoichi, Mousea and Cole. Ailee Lee gave this to Lana, Sabrina and Yoichi. Jace Whatever gave this to Yoichi, Hinata and Taylor. Mousea Mouse gave this to Clyde, Trisha and Hinata - which also meant that Mousea granted 3 people instant access to the jury phase.
*Double Eviction: In week 8, after Yoichi was evicted, the houseguests competed in a speed-week over the course of 20 minutes, with a HOH competition, nominations, POV, and eviction, leading to two evictions happening on Day 56.
*Jury Comeback: Before the week 9 HOH competition, the 4 jury members: Clyde, Ezzo, Yoichi and Doja Cat, competed in a series of 3 competitions (with 1 juror eliminated per competition) to determine a returnee to the house. Clyde was eliminated first, then Doja Cat, with Ezzo narrowly losing against Yoichi in the final stage, so Yoichi returned to the game.
*Power of Backdoor Invincibility: In week 10, the HOH competition also had a side-competition which would take longer but allow the opportunity to win a power. Cole won the power, which allowed him to give himself and one ally immunity for the week, bringing them to final 6 and therefore making them unable to be backdoored. He brought Lana with him.

===Week 1===
				
				
On premiere night, after Ailee had won the HOH, she immediately hatched a plan to target Doja Cat following her strong performance in the HOH competition. As a result, she nominated Doja Cat, with Yoichi as a pawn. As the week progressed, nominee Yoichi formed a visible showmance with Karla, which alarmed Ailee. After winning the POV competition, Ailee decided it was best to switch targets and to take a shot at the powerful showmance forming in the house, by using the POV on Doja Cat and naming Karla as the replacement, leaving the showmance as the final nominees. Her target was still Yoichi, due to him being a larger physical threat. On eviction night however, the majority alliance decided to blindside the HOH by flipping the vote, evicting Karla 7-6.
===Week 2===
			
			
After winning the HOH competition, Sabrina - who wasn't in on the blindside from the week prior - decided to try and take a shot at Sunmi or Taylor, who Sabrina believed were the ones to orchestrate the blindside. After nominating them, Sabrina's alliance began to discuss ideas around taking a shot at Ailee, someone the majority of the house was targetting, to make a better game move than taking out Sunmi or Taylor. Sabrina, hesitant at first, decided to keep her eyes on Sunmi, however didn't dismiss the idea. After Taylor won the POV and saved herself, Sabrina decided to nominate Ailee as the replacement, however was still unsure about who would be the better move to take out. Eventually, Sabrina decided it was better for her game to put her in good view of the majority of the house, and asked people in her alliance to evict Ailee. A new alliance containing Hinata, Jace, Lana, Luke, Ailee and Mousea attempted to get the votes to flip it onto Sunmi, however in the end they could not secure the votes needed, and Ailee was evicted 7-5.
===Week 3===
				
				
After becoming HOH, Cole initially planned to target Jace, Mousea or Ezzo as percieved threats in the house. After Ailee decided to blindside everyone by giving her Guardian Angel immunity to her 3 biggest enemies, Sabrina, Lana and Yoichi, Cole's plan went uninterrupted and nominated Mousea and Ezzo. After Trisha won the POV, it looked as if it would be discarded, however Cole decided to switch up the game by switching targets and attempting a backdoor against Jace. After successfully convincing Trisha to use the veto on Ezzo, Jace was nominated, with half the house being in on the plan to evict him, and the other half being oblivious to it. On eviction night, when many houseguests expected a unanimous Mousea eviction, Jace was evicted 6-5 after the HOH & his majority alliance flipped the vote as a blindside.
===Week 4===
			
			
After winning HOH, Lana's immediate target was Mousea, following the failed attempt to evict him in the previous week. Furious at the house for blindsiding them, Lana's allies were onboard with this idea and began attempting to recruit people to ensure Mousea was evicted. After Jace gave Guardian Angel immunity to Yoichi, Hinata and Taylor, Lana nominated Doja & Mousea with Mousea as the target. After Cole won the POV competition, Cole agreed to discard it due to him having no issue with Doja or Mousea being evicted. After the veto meeting however, Mousea began to effectively rally for votes in a desperate attempt to stay, a feat that almost worked causing the vote to tie 5-5, however Lana evicted him on this tiebreak vote.
===Week 5===
			
			
When Ezzo won HOH, him and his "Cabrizo" alliance with Cole and Sabrina immediately formed a plan to target Yoichi, due to his threat level as good in competitions and the fact that he had narrowly avoided eviction throughout the entire pre-jury phase, staying by 1 vote in week 1 and getting immunity through the previous 3 weeks. He was nominated alongside Sunmi as a pawn due to her position in the house being one that wouldn't upset too many people. After Ezzo won full power in the POV competition, these nominees remained the same with Yoichi as the target. Yoichi's alliance with Doja Cat, Hinata, Taylor and Trisha were all votes to keep him, however at the last minute, Cole - who wrongly estimated the votes - gave a pity vote to Yoichi expecting it to not impact the outcome, and to create drama in the house. Instead, due to his incorrect guessing, Yoichi received the 1 vote he needed to bring the majority to Sunmi, leading to her eviction by a vote of 5-4.
===Week 6===
			
After Hinata won HOH, him and his allies Doja Cat & Yoichi formed plans to target Cole, Ezzo and Sabrina due to their alliance. Hinata nomined Cole, with Clyde as a pawn, to prevent people from their alliance playing in the POV - which worked after both Ezzo & Sabrina remained unpicked in the POV. Cole won the POV and saved himself, making Hinata nominate Ezzo as the replacement next to Clyde, with Ezzo as the target. The Cabrizo alliance with Ezzo, Cole and Sabrina played hard though, and managed to rally enough votes to save Ezzo, blindsiding the HOH's alliance and evicting Clyde - which worked when Clyde left the house 6-2, with only Doja Cat & Yoichi voting for Ezzo.
===Week 7===
			
Doja Cat winning HOH extended the Doja, Hinata & Yoichi alliance's control over the house by another week, with them planning to finish the job against Ezzo which failed the week prior. Originally nominating him next to Taylor as a pawn, Taylor saved herself with the Power of Veto allowing for the plan to go uninterrupted to evict Ezzo, with Lana being the replacement. The Cabrizo alliance tried again to save Ezzo, with Cole & Sabrina convincing Trisha to flip her vote, however this was not enough to change the outcome, leading to Ezzo getting evicted 4-3.
===Week 8===
====Part 1====
			
Taylor winning HOH sent both Cabrizo (Cole & Sabrina) and Dohinichi (Doja, Hinata & Yoichi) into a spiral, due to Taylor's lack of alliegance to either side of the house, instead focusing exclusively on her final 2 with Trisha. Taylor's plan for the week was solely to evict the person she considered the biggest threats against her and Trisha, which lead her to nominating Luke & Yoichi, with Luke as a pawn and Yoichi as the target, with Cole in mind as a potential backdoor. After pulling houseguest's choice in the veto draws, Taylor picked Cole due to feeling bad about a full backdoor, which send distrust into Trisha as it meant she didn't get to play in the competition. Luke won the Power of Veto, saving himself, leaving Taylor to nominate Cole as the replacement. Still unsure about whether to evict Yoichi or Cole, she eventually decided to go after Yoichi as it would level out the numbers held by each alliance, leaving the game as a 2v2v2v2 going into the following week (Taylor & Trisha, Cole & Sabrina, Doja Cat & Hinata, and Luke & Lana). This plan worked, with only Doja Cat & Hinata voting for Cole, leaving Yoichi evicted 4-2.
====Part 2====
				
After Yoichi was evicted, Allison called the houseguests to the living room announcing that the night was a Double Eviction. Trisha won the HOH, extending Taylor & Trisha's control over the house, with a plan quickly formed to repeat the formula from last week by nominating one houseguest from Cabrizo and one from Dohinichi. Trisha nominated Doja Cat & Cole, with Doja Cat as the target. In the POV competition, Lana won, leading the entire house to expect her to discard it, however she decided to play messy and save Cole in an attempt to get Sabrina backdoored. Trisha did nominate Sabrina, however Lana ended up being the only person to vote for her, with Doja Cat leaving 4-1, with even Hinata voting against her.
===Week 9===
			
On day 57, before the HOH competition, the houseguests were told to gather outside, where they were met by Clyde, Ezzo, Yoichi and Doja Cat competing in a comeback competition, with Yoichi winning. This brought the house dynamic back to 2v2v2v2, being Sabrina & Cole, Lana & Luke, Taylor & Trisha, and the newly re-united Hinata & Yoichi. After Yoichi won, all 3 other pairs named him as their #1 target for the week. This was followed through with when Sabrina won HOH, nominating Yoichi alongside Sabrina's closest ally Cole, who was nominated as a pawn to guarantee playing in the Veto. The POV competition was a prize pyramid, with Luke winning a slime punishment, Sabrina winning 2 weeks of slop, Hinata winning a letter from home, Cole winning $1,000, Trisha winning a vacation, and Yoichi - to the rest of the house's dismay - winning the POV. After saving himself, Sabrina & Cole planned to go after the next biggest threat, Taylor, in order to split up the power duo of her & Trisha. This target was sucessful, with Taylor being evicted 4-1, with even Trisha voting her out. Yoichi was the 1 vote against Cole, who claimed he did it to 'send a message'.
===Week 10===
			
			
Before the HOH competition, tensions between Sabrina & Cole began to rise, with Sabrina accusing Cole of abandoning her for Lana, which was correct. By the time Yoichi had won HOH, much of the house dynamic from previously had been torn apart as a result of several factors. As well as Lana & Cole forming a final 2, Yoichi & Hinata had fought and ended their alliance, with Hinata siding with under-the-radar Luke (who was still partially aligned with Lana), and ironically, Yoichi also became closer with Luke without the knowledge of Hinata's alliance with him. In the HOH competition, Cole had won the power to give immunity to himself and one ally, of which he picked Lana, making them both safe for the week. This did not disrupt Yoichi's plans, as he decided to nominate Hinata & Trisha, with Hinata as his target and Trisha as a pawn. After Trisha won & saved herself with the Power of Veto, Yoichi nominated Sabrina due to his newfound alliance with the only other option, Luke. The target remained Hinata throughout the week, with everyone onboard to evict him. At the eviction, Cole, Lana & Trisha voted to evict Hinata as planned, with Luke flipping and voting for Sabrina as a pity vote to Hinata & for jury management. Hinata was evicted 3-1.
===Week 11===
		
Throughout the last few days, Cole & Lana had been reuniting with former ally Sabrina and had reformed the Cabrizo alliance with the 3 of them. After Sabrina won HOH, Sabrina swore her loyalty to them and to not nominate any of them in the week. She kept this promise, nominating Yoichi & Trisha who had their "Outsiders" alliance exposed, not knowing that neither of them were loyal to the alliance. The target was Trisha, due to her being in a better position in the game and having higher threat levels, however Cabrizo decided to lie to the nominees + Luke, making Yoichi out to be the target to make him panic and potentially blow up his game, putting them in a good position to evict him next week. After Sabrina won full power in the POV competition, she kept her nominees & target the same, while continuing the lie to the other half of the house. On eviction night, with Yoichi, Trisha and Luke all preparing for Yoichi to get evicted, Cole & Lana voted for Trisha leaving Luke as the only vote for Yoichi, making Trisha evicted 2-1 and blindsiding the other half of the house.
===Week 12===
			
The house dynamic of the week was immediately clear from before the HOH competition, with Cole & Lana's final 2 being as strong as ever, Luke & Yoichi becoming closer by the day, however with Sabrina losing trust in her alliance with Cole & Lana. Cole & Lana had been having discussions about Sabrina's competition threat ability, and had decided that it would be worth considering to get her out if they had power this week. After Lana won HOH, they progressed with this target, nominating Luke as a pawn next to Sabrina, with Yoichi as a potential replacement option later on. This was shocking to Luke, Yoichi & Sabrina who had all expected Yoichi to go up as an enemy of Lana's closest ally, Cole. After Cole won the POV competition, the rest of the house expected him to use it to backdoor Yoichi, however instead he discarded it, leaving Luke & Sabrina nominated. On eviction night, the house decided it was time to evict Sabrina, rather than wasting a week evicting non-threat Luke, and so Sabrina was evicted 2-0 in the first unanimous vote of the season, with both Cole & Yoichi voting her out.
===Week 13===
		
Going into the final week, in true fashion of the season, both alliances crumbled at the last minute. Lana & Cole had a fight and ended their final 2 deal, leaving Lana alone. Luke & Yoichi also ended their final 2 deal, although technically they had agreed to end it at the final 4 several weeks ago as they had called it a "safety deal" rather than a final 2. Cole decided to approach Luke with an agreement to attempt to bring eachother to the final 3 if either of them won the HOH, while Yoichi & Lana did not form any new deals. After Luke won the HOH, he kept his word to Cole and nominated Lana & Yoichi. After Luke also won the POV, he decided to be loyal and keep the nominees the same, however asked Cole to evict Lana due to feeling bad about betraying Yoichi. Cole obligued, happy to evict someone who would no longer take him to the final 2, and to potentially collect a loyalty jury vote from Luke should he be evicted. As a result, Lana was evicted, bring Cole, Luke & Yoichi to the Final 3.
===Week 14===
		
Entering the final week, none of the final 3 had any alignment to eachother anymore, and were all playing for themselves. The first part of the HOH, the endurance round, was won by Cole, progressing him directly to Part 3. Part 2 was then won by Yoichi, leaving Luke as the first nominee as Cole & Yoichi competed in Part 3 for the HOH. In part 3, the houseguests were both tied through most of the rounds, until the final question of the set, where Cole got a point that Yoichi didn't, giving him the win. Cole chose to evict Luke due to his underdog gameplay which could've been rewarded, and due to his friendships in the jury. This meant that Cole & Yoichi were the final 2 houseguests of the season. 
===Finale===
	
At the finale, each juror casted their votes for who they wanted to win between Yoichi & Cole. In the end, Yoichi received 6 votes against Cole's 3, making Yoichi the winner of Big Brother 4, and of $750,000.
At the America's Favourite Player reveal, the top 3 was Hinata, Lana & Yoichi, with Hinata ending in 3rd, followed by Lana in 2nd and Yoichi being America's Favourite Player, bringing his total earnings to $825,000.
