Big Brother 5

Big Brother 5 was the fifth mainline season of Big Brother, and ninth in the franchise. It features 16 houseguests, and aired from 1 to 14 April 2024. It was won by Kate Cosmic, winning 6-3 to Nemo Mettler.
==Background==
The season was confirmed for renewal in October 2023, alongside Big Brother UK which aired that October. No more information about the season was revealed until the finale of Danganronpa in March 2024, where it was revealed that Big Brother 5 would be starting in April. The cast was revealed on 31 March 2024, with the season itself beginning on the next day, 1 April, around 5 months after Big Brother UK began.
==Twists==
* Gambling Season: On premiere night, Judi revealed that this season was a 'season relying on luck and gambling'. The first HOH competition was part of this, with the HOH, a $10,000 prize, 4 immunities, and 1 third nominee were decided completely by chance.
* Coin Flip: In the first 5 weeks, a houseguest would be able to earn a Coin. If they were an initial nominee, they could use their coin to do a Coin Flip, for a 50% chance at being saved. The HOH would name the replacement. The last week they could use these was week 6.
* Vacation Ticket: Before the Week 7 HOH competition, Sarah was voted by the audience to receive a Vacation Ticket, giving her the whole week to stay alone in a luxury resort in Hawaii for the week, and therefore being temporarily out of the game, missing both the main week and double eviction.
* Roulette: In weeks 8 and 9, a roulette wheel containing all players was secretly spun, with the winner earning the ability to anonymously name a third nominee. The HOH could also be the roulette winner.

===Week 1===
				
				
After the first HOH competition, Glados allied with punishment-nominated Karla, and attempted to work with her to ensure her safety. She made several enemies after nominating Ezzo for his history with competitions outside the house, and Sarah from the $10,000 she won, and plans to vote Karla out began to arise in the house. Glados' target, Sarah, won the Power of Veto competition, which put a wrench in her plans as she was forced to nominate Nemo, who became her new target despite Glados not necesserily wanting them gone. On eviction night, the vote was close, with Glados' half of the house (including best friends Cole & Jen) voting for Nemo, however the opposition had the control, with 6 votes to evict Karla, and Mousea throwing a rogue vote at Ezzo.
===Week 2===
				
Through both weeks, a 'love triangle' had formed between Luke and Kate, with Joker at the centre. When Kate won the HOH competition, she found out about Joker's relationship with Luke, and planned to split the triangle up in revenge. She nominated Joker, with Ezzo as a pawn, and planned to backdoor Luke. When Mousea won the POV, he used the power to take his new final 2 Ezzo down, and Kate nominated Luke as a replacement. While her target was Luke for much of the week, as Day 14 approached, she decided to let the house have the decision; saying that either she got to have Joker, or neither of them. While most of the house voted Joker out due to his position as a social threat, Joker's alliance (containing Glados, Sarah and Jen) voted for Luke in attempt to keep Joker in the game, leading to a 9-3 vote for Joker to be evicted.
===Week 3===
				
After Joker's eviction, a "majority" alliance was solidified with Cole, Jen, Sarah, Glados, Daniel and Ezzo. Ezzo also had a final 3 with Mousea and Kate, and Kate had a showmance with Kazuichi. These interlocking alliances technically gave that side of the house a 9:5 split of control going into the week. When Daniel won the HOH, his target was Luke, following the love triangle fiasco of the previous week, and a rivalry between Luke and Daniel. He nominated Ezzo as a pawn, and Luke, who attempted a coin flip but failed, and stayed nominated. When Kate won the Veto, she used it to save her new final 3 ally Ezzo, who was then replaced by Bambie. Most of the house was in agreement to vote Luke out, except for Cole, Ezzo and Sarah who secretly agreed to vote Bambie in attempt to throw the house off and potentially frame new people as targets. They were the only 3 to vote for Bambie, resulting in an 8-3 vote for Luke to be evicted.
===Week 4===
				
When Kate won her second HOH, her initial plan was to evict Bambie with whom she had fought with previously. She nominated them alongside Jen as a pawn, who was nominated as Kate thought she was likely to get the votes to stay. In the POV competition, Kalynn began sabotaging Kate in attempt to get her final 2 Bambie to win, which did not go unnoticed by Kate. Within the last few seconds of the competition, Kate, not being able to win herself, managed to make Kalynn victorious, which would later force her to reveal their allegance when Kalynn used the veto on Bambie. During the week, Kate had noticed Jen and Cole being close, and, after her target was vetoed, she nominated Cole alongside Jen to split their final 2 up. With Jen & Cole as the final nominees, Kate set her sights on getting Jen evicted. The non-nominated members of the majority alliance (Ezzo, Glados, Sarah & Daniel) all planned on voting out Cole, as they felt he was less loyal to their alliance than Jen. They also managed to convince Trina to vote alongside them, which brought the vote split to 5-5. However, when it came to the tiebreak, Kate stuck with her original plan and cast the tiebreaking vote against Jen.
===Week 5===
		
At the start of the week, it was discovered by the main alliance (Glados, Sarah, Cole & Ezzo) that their fifth member, Daniel, had been leaking information about the alliance to other people in the house, notably Nemo and Kate. As such, when Sarah won the HOH competition, she and the alliance planned to target Daniel for eviction. She nominated Daniel alongside pawn Nemo, with Kate as a planned replacement if the veto ended up being used. Cole specifically wanted Kate evicted over Nemo or Daniel, however he narrowly lost the veto competition to Sarah who kept her nominees the same. In the vote, Bambie, Mousea and Trina voted to keep Daniel in attempt to give their side of the house a former member of the alliance, however the majority of the house voted to evict Daniel, and he was evicted 6-3. Surprisingly, Kate and Kalynn (who would've benefitted from keeping Daniel) voted to evict him, seemingly because they didn't think they had the votes, whereas their votes would've caused him to stay.
===Week 6===
					
Trina's HOH victory sparked panic across the rest of the house, as she was aligned with nobody and her position was unclear. She worked alongside Kate to nominate their common enemy Cole, with Trina stating that he was her target, and that he "should've been evicted weeks ago". Cole was nominated alongside pawn Mousea, who was saved by his coin flip and replaced by another pawn, Kazuichi. Cole's coin flip failed, and he remained nominated. In the POV competition, Glados, aligned with Cole, came out with a landslide victory and saved him, with Trina's replacement being Ezzo, and the target being switched to Kazuichi. At the vote, the F2 Bambie and Kalynn voted for Ezzo, along with Glados who threw a sympathy vote thinking Bambie & Kalynn wouldn't. The rest of the house voted Kazuichi, making Kazuichi the first juror in a 5-3 vote. Notably, Kate voted to evict her showmance Kazuichi, stating that as hard as it was, keeping Ezzo (who she was in a final 3 with) would be better for her game.
===Week 7===
Sarah received the most audience votes to receive a Vacation Ticket, and therefore got to spend the entire week (including the double eviction) in a luxury resort in Hawaii. This made her ineligable for nomination but also unable to participate in any competitions, or communicate with anyone in the house.
====Round 1====
			
At this stage in the game, the house had essentially been split into two halves; Sarah (on vacation), Glados, Cole, Ezzo and Mousea on the first side, and Bambie, Kalynn and Trina on the other side, with Kate and Nemo playing both sides. When Bambie became HOH, they repeated their ally Trina's nominations from last week, nominating Cole and Mousea for the same reasons as Trina, with Cole as the target. When Mousea pulled out the POV win and saved himself, Bambie took the opportunity to make a risky move, and nominated their number 1 ally Kalynn, in attempt to stage a fight and make it look as though they were no longer aligned. This worked, and Cole left in a 5-1 vote, with Glados throwing a sympathy vote. 
====Round 2====
			
After being surprised with a Double Eviction, the HOH competition was almost won by Kate, however she threw at the last second in order to have a shot at winning the next HOH. Nemo won in her place, and nominated Ezzo and Glados, with Glados as the target, as she was largely considered the 'leader' of the other side of the house. Nemo's close ally, Kate, won the veto, and despite being allied with Ezzo, discarded the power. She made this decision as she felt that, while Ezzo had the votes to stay, Mousea could've potentially been the replacement and could've potentially been evicted, as well as wanting to keep her ally Nemo happy. Nemo's plan to evict Glados worked, with Bambie throwing a sympathy vote, and Glados being evicted 4-1. Sarah returned to the house immediately after Glados' eviction interview.
===Week 8===
				
After winning the Roulette, Kalynn confided in the HOH, Kate, in attempt to earn trust with her. Kate, knowing about the final 3 between Kalynn, Trina and Bambie, convinced Kalynn to nominate her ally Trina in exchange for safety. Kate then nominated Kalynn's other ally, Bambie, along Sarah as a pawn, as Sarah had the most chance of winning the veto. When Sarah won the veto and saved herself, Kate went back on her word and nominated Kalynn, meaning all 3 members of their final 3 were nominated. Kate secretly exposed Kalynn as Roulette winner, getting Kalynn evicted with 3 votes, with Mousea throwing a pity vote at Trina. 
===Week 9===
				
After Trina's HOH win, Ezzo accidentally slipped up in conversation with her and revealed the final 3 between Mousea, Ezzo and Kate. Trina, in attempt to regain power in the game, nominated Ezzo and Mousea, with Kate as an intended replacement, in order to ensure one member of their final 3 was evicted. Ezzo, the roulette winner, anonymously nominated Sarah, secretly betraying his alliance with her in attempt to prioritise his final 3. After Sarah managed to win her fourth veto and saved herself, Ezzo had the ability to select a new nominee, and chose Bambie, Trina's closest ally. At the vote, Kate, who was mad at Ezzo for exposing the alliance, voted Ezzo out, while Nemo and Sarah voted for Bambie, making Bambie the fifth juror by a 2-1-0 vote.
===Week 10===
				
When Kate won her fourth HOH, her immediate target was Sarah, who was giving her a run for her money in competition wins and social influence. She nominated Sarah with Nemo as a pawn, to disguise her allegance with Nemo to her final 3 with Ezzo and Mousea. Kate, when Mousea won the veto, convinced him to save Nemo, after it became apparant that Mousea, Ezzo and Trina (the voters) may have ended up voting Nemo out. While Kate had intended to evict Sarah, it became clear that the voters allegance to Sarah was too strong for her to get voted out, and so Kate nominated Trina as collateral damage knowing that in the likely event of her getting evicted, while not the best outcome, would be better for her than Nemo or a member of her final 3 leaving. In the vote, Mousea, Ezzo and Nemo all voted to evict Trina, against the will of the HOH, leading to the first unanimous eviction of the season.
===Week 11===
			
After Ezzo's first HOH win, the house dynamic immediately shifted greatly. Ezzo, who previously was closely aligned with Sarah in a final 2, as well as having a final 3 with Kate and Mousea, nominated Sarah against Kate as he deemed them the two biggest threats to his game. At this stage, he had also formed a new final 2 with non-threat Nemo, considering them to be the easiest competitor to win against in a final 2. After Kate saved herself with the veto, Ezzo nominated his other ex-ally, Mousea, with Sarah as the target. While it looked clear that Sarah was to be evicted, Sarah, in a last-ditch effort to stay, formed a last minute final 2 with Nemo to win their vote. As a result, Nemo voted for Mousea, forcing a tie, however this was unsuccesful on Sarah's part as Ezzo split the tie to evict her.
===Week 12===
		
At this stage in the game, all alliances had essentially dissolved as all players were playing for themselves and themselves only. As a result, after Mousea won the HOH, he immediately betrayed his season-long final 3 by nominating both of them, and keeping them nominated after winning the POV, as he believed they were two huge threats compared to Nemo who hadn't really done anything. Nemo voted to evict Ezzo, as they had been aligned with Kate for much of the game and still felt a loyalty to her.
