I think Pratik has been as close to flawless as possible in BBOTT and hopefully win the show.
1) He has raised his voice on all issues and even gone against his friends instead of blindly supporting them when he felt it was right.
2) Every one who fought with him has come out looking worse and their inner nastiness has been exposed eg. Shamita's woman card, Rakesh's racism and superiority complex, Zeeshan's violent nature leading to his eviction etc. while he has controlled his words and actions.
3) He initially looked negative while changing partners because of audience's slightly over the top dislike of Neha. But it totally made sense from his perspective coz he had nothing in common with Akshara while Neha and him are very comfortable together. This has been further proved to be a correct decision coz Akshara herself is a very nasty piece of work with a regressive mindset while Neha literally saved his ass today by refusing to go the rickshaw even when it meant she would be safe.
4) He stood by his first friends Nishant and Moose whenever he could. The one time he didnt was not for lack of trying. His hands were tied because Neha had to stand up for her friend Shamita as well which was totally right on her part. But, it has been a big eye opener because Moose was ready to throw him under the bus today even when she herself was safe and could have easily ensured his safety at the expense of Divya (whom she was fighting with only 2 days back).
5) He has always showed passion for the game, the opportunity and got visibly upset when audience report card was negative or medium. He has played all tasks to the best of his ability even when he was ill or the "sanchalaks" were clearly looking to eliminate him at the first chance.
6) The only part of his game I dont agree with his is his continued hostility toward Divya. While she has talked ill about him to others, I feel she would immediately become his friend if he approaches her and tries to fix things. She cares for him I feel. This is the only reason I feel he has not been fully flawless.
If he was a popular or semi popular face instead of an almost nobody, I would have been sure he would win this season hands down. As it stands, I am only 50% confident. Lets see what happens.
