Rahul isn't going to win.
Dipika was only behind Sree by like 6-7% on Social Media polls, and actually most neutrals were supporting Dipika over Sree. It's reflected in Ormax which she won -- Ormax doesn't calculate based on social media popularity, but it surveys across all of India including rural areas. That season Sree was a little more popular in social media, but Dipika was most loved by India as a whole. (Whether I agree with it or not is a different matter)
In this season Rubina is ruling even social media and Ormax. I can't see her getting defeated -- not only will she win, but she'll win by a huge margin.
As for if makers try the scene paltao it's only gonna backfire on them because their credibility can def be questioned this season if Rubina doesn't win.
I know they don't want her to win though, but what can they do, when their votes are audited? Unless they cheat the votes somehow, she will win. 😆
