I will say this is great move
Vikas always show his supremacy as if he is the one who is controlling all housemate decision. It was as if he is the owner whom he can make caption .. he was doing so by keeping Hiten, Arshi, Puneesh to his side and by acting very sweat to Shilpa as he knows Shilpa will agree for anything if he talks sweetly.
After she saw Vikas color and she got re-confirmation that he is playing with her, she made one of her Pyada Out... now he will have only Arshi and Punesh. She knows that Puneesh is on her side, so now he will be left out with only one Arshi
Arshi is way too smart and she is with Vikas because she knows he is most influential with all person agreeing to his view... so she might also flip and goes to Hina completely
by taking this move, even Priyank/Luv will have soft corner for Shilpa
and Those Who Are talking About Hiten Saving Shilpa... You are totally wrong. He himself admitted that he would have saved Arshi and Not Shilpa... He saved Shilpa Just Because He Wanted to Return the Favor because Shilpa also Saved him once
At any time, Hiten would have never supported Shilpa on his own... he would have just followed what Vikash would have said to him,,, and we know how much Vikash love Shilpa
It was must for her to corner Vikash so that he does not control the whole house again. If Priyank would have gone out... He still would have 4 person on his side... & 2 person on Hina Side. In this case, all task result would have happened as per Vikash instruction...she played great... who says Vikash is Mastermind... Uska Lul Ho Gaya
