she's absolutely dominated this season since week 1 and has decided who went home each week. Even when she wasn't in the numbers majority after The Six turned on her for Emily/Dillon, her and Demetres were STILL the swing votes each week, having almost every nominee have to beg them to stay.
Ika probably won't win this season because Dillon/Dre/Karen have bonded over wanting all the veterans out, and William is more loyal to Kevin than to anyone else so unless Ika/Demetres go on a competition run, they won't win this season but Ika has absolutely DEFINED this season and has played one of the best returnee games for how poorly she played in her original season.
