SS telling abt a woman similar to Pratigya obviously is the next storyline. And the questions posed by you make a lot of sense. Chances are that Aman is related to the Thakurs and quite possible Ghanti Dai cld have decided to to take the maun vrath since then . It cld be the reason she is so sympathetic towards Pratigya as she must remind her of that other woman.
If Aman is related to the Thakurs then I am depressed. If the article is to be believed Aman is a lead for Aarushi which means Aarushi will end up in the Thakur parivaar which means she won't get married and quit the show.
So after winning over Krishna, it cld be that Pratigya's new Pratigya will be to uncover the mystery of this woman and then eventually bring Aman into the family if he is related to them.
Now regarding the bedroom scene. Krishna looked like a shattered porcelain doll. Thank the lord that Pratagiya did mention the reasons for her marriage but i think all those things just reached Baba's ears but never registered.
I liked that u had words of praise for Pratigya but i am still not ready to forgive her. Krishna should continue with the cold treatment.
