She is here for the same reason - vulgarity and cheapness. I liked her in season14 till she refused to understand the importance of concent. When someone says 'no', it means 'no'. Credit should be given to Salman to encourage her vulgarity. Last season, she was forcefully taken to finale by removing Abhinav without voting from audience and didn't let Eijaz to re enter the show. Otherwise she wouldn't have reached to finale. If I'm not wrong Niki was the one who pressed the buzzer first for the suitcase, but money was given to Rakhi.
This season it looks like they will sacrifice Umar or Pratik without voting to make a way for Rakhi's nautanki in finale. It's not possible to remove Karan and Tejaswi through voting and BB team is interested in their fake love angle, Shamita ko khud big boss godi me utha ke le jayenge finale tak. So it's between Umar and Pratik- Kaun banega bali ka bakra Rakhi Maharani ke liye.
