I've seen a edition of Big Brother Brasil with this twist. I think four housemates went in and the first to click the red buton was evicted. I think the same happened in the original australian version. Usually they give money to the first housemate that quits so that might be what the 25000£ are for.
I really hope not, we could lose a great housemate so clos to the final! Tbh, between giving a free pass to the final and evicting a housemate, I definetely prefer a final pass.
