If anything I think Isabelle defied the odds. She went in as a latecomer with very little support, was topping the eviction vote when all were housemates up, destroyed lotan who tried to be alpha male, won the hearts of the nation and had a massive turnaroud and then beat a superfan in the final who knows the show “inside out”
Plus in terms of descriptions, a bleach blonde bronze young girl is very unlikely to be thought of winning Big Brother.
I can understand why Raph must find it strange to see people discussing him and his big brother friends, and it’s sad to see him feel this way. But I guess he knew this sort of thing would happen if he went on the show and also posts on a discussion forum.
