I think that there is more then one person involved in blackmailing Thakral...it's a big mystery!!!!
Well, from the beginning, I thought that Jhanvi is involved and then I thought it was Sid and then I thought it was Sushant...I started to think that it was a combination....
Up until that episode where Diwakar thru the pictures of Thakral at his face, then I was like ok so it's him?!?!
Now, I think that it is a group effort..Jhanvi, Sushat and Sid...I also have thh suspicion that Diwakar is still alive...
the reason I say this is that to date all the people that Thakral has murdered we have see a bead body and the blackmailer has sent Thakral the usual pictures of his crime...the only time that he did not get any pictures was when Diwakar was killed..also, we never saw his dead body...the last we saw of him was that he was badly hurt and alive but barely...Thakral did say that is threw his body in the daldal when Rachna asked where he was later...but I think that he lied becuase all his men had left when Rachna found Diwakar...I think that one of the blackmailers took Diwakar and we will see him again....
So, my theory is that Sushant and his father are now against Thakral and they wanted to get revenge..Sushant got Jhanvi on board and Diwakar was also bought into the conpiracy somehow and then Sid is also involved somewhere in the blackamiling but he has is own intentions as he is working both sides....So, in the end it is a group effort by all these people...
I'm not too sure about Baccha Singh, sometimes I think that he is involved and sometimes not...right now I think that he is not involved...
I don't know if this is right but we will have to wait and watch what is in store for Kaali....
I also think that this story is going to go one for atleast a few more months....
