Only people I absolutely do not want to win are Coco or Conor.
-Coco because she's just a nasty person on the streams, she turns against everybody in the house, talks badly behind their backs, then plays victim when she gets called out, and sobs. Even with Holly gone, Coco's turned against Allana and Conor now. She's the definition of a 'cry-bully' and is clearly desperate to win the money, always using the "my three kids" line to garner support from the public.
I actually now feel sorry for Bruce for having to deal with this woman.
-Conor because he thinks he is intellectually and morally superior to everybody, is extremely arrogant and controlling. Clearly playing the game by using his backstory to garner support from the non-invested 'normie' type viewers. It would be extremely satisfying to see him not win for this very reason.
Unfortunately, both of them have some form of sob story that will attract the low-IQ sympathy voters from the Australian public that just tune in without even paying attention to the show or live streams where the housemates' true colours are shown.
