All have been biased during their moderation in the house so they shouldn't be the ones complaining about Rakhi as they too used to make their friends win blindly in the VIP tasks whether it's Karan, Teja, Umar, Debo, Nishant, Shamita and Rakhi. The problem arose when it came to individual games and fighting for themselves after the VIPs got downgraded and now it's come to Karan vs Teja. As far as what I've read and heard on LF, Karan got support of all except Rakhi and Debo while Teja's support is still in the air so she's right somewhere to support an unfair moderator as she still has chances with Debo (if Debo keeps her word). I can see Karan having a problem with that which is again fair enough but since he's been constantly with her and having a relationship, it looks weird as she did not show an issue with Umar or the others supporting Karan. She has always had a doubt that nobody in the house will support her, even Karan.
Ultimately, one contestant will win the trophy so whoever even reaches the finale week, it's sure that Karan and Teja will be in the finale.
I feel bad for Umar as in comparison with others, he has lesser chances to be in the top 5. The show isn't favoring him and he's being dumb by playing for Karan when Karan will only play for himself. He should treat him as a competition now. Friends, girlfriends all shouldn't matter.
