1. Firstly there is no couple shipping. When someone is calling ViNa its for a matter of convenience. They have their priorities set, and we as fans respect that. And almost all the supposedly ViNa fans want them together for this show or next show but not in real life.
2. Vikas and Hina were always at loggerheads in tasks, but had a pretty cordial relationship out of tasks. Their session of bitching and fighting was always there but it wasn't obsession which few have for Vikas. Now that they have no one left, and due to other things happening in and out of BB, they warmed up which technically isn't a crime.
3. Even if the relationship is fake, and one is using the other, it doesn't matter, coz the rest of the house is even more selfish and mean and what not... better to ignore the rest.
4. We as fans, atleast for now want Hina to win if not Vikas, not coz we doubt Vikas talent or his fandom power. But we doubt BB and their dirty games. So for me, if not Vikas its Hina, having said that when its Vikas vs Hina, there is no doubt that il put my 100% efforts for Vikas only. Not wrong in having second option, but its SECOND option , which only comes when first isn't possible.
This is the finale week, and everyone will be playing individually only but with such a biased host and undeserving top 5(I mean only Changu Mangu, coz though i hate Shilpa, she is deserving) , selective editing, there is no harm in Vikas and Hina being cordial with each other. Vikas is competitive and smart enough to keep his priorities.
I somewhat guess its the same with Hina and her fans too.
Vikas FTW
