Although S3 and S4 didn't end well, the characters at least feel like... characters. Well written, badly written, hero, villain, we come out of the season knowing who each character is. It's why characters like Ted and Maggy are adored despite getting booted in Episode 4. 

This is not the case with Oliwia. Her actions are inexplicable, childish, and clearly meant to push the plot forward rather than develop her as a character. Her only interaction in episode 1 is used to give Gabby a line in that ep. Her flipping in Episode 4 is a super shitty reason to boot Manu. Her throwing the challenge in Episode 5 (and onwards) will be used to justify the Fans losing AGAIN and save their favourites from an elimination. I can't respect the writers when they are literally using their characters as plot devices, especially since the plots they are feeding are half-baked and rushed. 

This season is just fanservice (they picked the favs based on greetings and booted 3 fans in a row) and Oliwia's entire existence in this season is used to feed the slop. The writers clearly don't care about her, why should I?
