Well if you think making a close connection or being someone's best friend means ke insaan chamcha ban jata hai, i disagree.
Sure Asim and Siddharth talk alot, but they play their game very differently.
Had Asim been Siddharth's "chamcha" then he would follow his footsteps and not stop him from being violent for example on the first day of the snakes and ladders task, Asim was pulling Siddharth away, yelling at him, and explaining to him that he was wrong (He is not agreeing to Siddharths words or actions all the time).
Again for someone who was just a model before entering Bigg Boss Asim has become a very strong contender, and I feel since he has never done something like this with cameras on him 24/7, he hasn't got the chance to practice being fake. For me Asim is the realest in the house right now.
So for those of you supporting Arhaan a.k.a Jerry Trainor cool, but I think Asim is better. I also agree with Asim when he called Arhaan a "batakh ti hui aatma" (I would prefer "mandrati hui makhi") because Arhaan involves himself where he doesn't need to be, and I understand he need to make connections as he has just entered the show, but he should find the appropriate situations to place himself.
