Big Brother fans are already fuming ahead of tonight's episode which will see another back-door eviction, with one housemate given the chance to pocket £10,000 from the prize pot.
Some viewers of the reality series are even calling the latest twist 'unfair' as the show has introduced a new feature as the final week gets underway.
Revealed during last night's (Sunday, November 10) edition of companion show Late & Live, four housemates will enter Big Brother's vault in Monday's (November 11) episode. One contestant will get to choose the three who enters with them, however one of them will not return afterwards.
A message posted by the official X account, read: "Today four Housemates entered Big Brother ’s vault, but only three made it out…
"One Housemate drew a lucky pound sign card, gaining the power to pick three others to join them in the vault. But there’s a catch, the chosen Housemate with the fewest public votes won’t be returning!
" In a final twist, the lucky cardholder got two £5k bundles to place in front of the Housemate or Housemates they think are safe. If they guess right, they keep the cash."
After Lily and Khaled left the house in a shock double eviction last week, remaining housemates who may have drawn the pound card include Ali, Hanah, Baked Potato, Marcello, Emma, Thomas, Segun, Nathan, and Sarah.
Only six of those will make it to the final on Friday, meaning there could be another surprise eviction even after tonight's episode.
Not all viewers are excited about the latest developments involving Big Brother's vault, with some making suggestions for how the show can avoid 'horrific twists' in the future.
One responded on social media, saying: "Please just start the series 3 weeks earlier next year and do more double evictions so we don’t have to deal with horrific twists like this in the final week. Oh, and don’t call it a ‘vote to win’ if you’re not going to evict the person with the least overall votes."
Another said: "You guys need a serious rethink before next year because this is a damn mess."
Meanwhile, one fan declared that this latest flash eviction was unfair in regards to the competition overall, adding that the public, who have been voting for who they want to win, weren't really told what they were actually voting for.
They added: "Big Brother vault example: Sarah (9th) picks the envelope, chooses Ali (1st), Hanah (2nd) and Emma (3rd). Emma gets evicted, Sarah stays and has a chance of winning 10K! How is this fair?"
