Nah I disagree. I think Asim Sana and even Shukla (lol) are more deserving than Rashmi. I like her as a person, and you're right there has been considerable growth in her game after Arhaan's second exit, but she has not shown herself to be winner material for me at all. Plus we know for a fact that the first half of her time on the show was scripted to some degree. Arhaan came, she acted surprised, they claimed to be not-so-close friends and pretended to fall in love on the show. Then, when the drama with Arhaan's secret kid happened, we learned that him getting exposure was one of her damn reasons to do it in the first place and plus they have been in a serious relationship for a long time that he helped her overcome a long financially difficult phase. This entire act put a sour taste in my mouth for her. The one story she had besides dushmani with Shukla (from before) and dosti with Devo (from before) was this and it turned out to be fake. She seems like a good person, but not winner material for me at all. In fact, even taskwise she has only impressed twice (katputli and recent elite club task) which is not a good average for a potential winner on the 17th running week.
Asim does have some traits of Shukla, but he is not just another Shukla, who doesn't go on family. He is always the first to apologize when he realizes a mistake. He is nothing but respectful when Salman scolds him, sometimes for the silliest thing. And no matter how bad a relationship gets - he always sticks up for someone alone and consoles someone in tears. He has an aggression and ego problem for sure, but he is SO MUCH more than a younger Shukla in my opinion. Looking at his journey, especially considering he has endured more than any BB contestant ever (as the victim of repeated violence which was never before allowed on the show) he is 100% winner material.
Sana does go overboard sometimes and is a little cringy lol but she is entertaining by herself. She became unbearable for me during the peak SidNaaz phase because we all know she was just acting the roz ka 'nok-jhoks' because she kept getting so much feedback that the couple is being loved on screen. She is much more winner material for me than Rashmi because she has always had a strong presence on the show, and has never disappeared into the background like Rashmi has sometimes for over a week! I think a 2nd or 3rd spot is ideal for her.
