Did anyone else get the vibe that Tarun could possibly be the murderer of Sahil? He is always with Bani during the investigation and points at various other people in the house. Moreover, in the handycam the feet of the murderer seems to resemble Tarun's feet. The killer can't be Jai Walia, like some people think, he would never hurt Bani, that's not possible. Or perhaps he is trying to trap JW, he was very much against bani forgiving Jai and now we know that he secretly likes bani....
Anyways, thats just my opinion
