1 . Deknese saree me vo lady jaise hey but from a part of her face which is visible to us , I don't think she is a lady , a gent might be dressed up like that . But her voice is like a lady .
2. She is a bit tall . So Puttan might not be the person who came .
3. Puttan was not there in home when Ganga came with money ( Bua gave this info in the epi ).
From these things , I think that Puttan might have kept a person for blackmailing her , might be a lady or gent ( by doing mimicry to resemble a lady , so that Ganga won't get doubt on Puttan ) .
4. Bua thinks there is something different going on and follows Ganga .
This means that Bua doesn't know anything about this blackmailing plan .
