Was he Mastana

I had a feeling that the black dress guy who took papers from file was Mastana.
Lookslike maasaheb had him in duty to keep an eye on all the family members.
It's her plan so that she will not get bail.
In the end she will realize that pari is a good person

Yes, but I wonder how long it will take her to figure out. As it is right now Babita and the gang are out to frame Pari so it might take sometime for the truth to come out. I just Maa Sab is smart enough to figure it out sooner rather than later (hopefully Babita and gang will be pouring just a bit too much honey on their goodness act and Maa Sab will be able to smell a rat...)
