This is what Wikipedia page of Kusum Dola says:-
Emon brings Badshah back into the house. Badshah wants to free Roopkatha from their namesake relationship but she proposes they continue using it to stay close to Rono. Emon finally confesses love to Rono on his birthday. A devastated Roopkatha tries to accuse Rono of impregnating her but seeing Emon's faith in Rono's innocence, she backs down and is about to leave the house when she is asked to stay by Badhsah and the family.
So this means that Sai will bring Samrat back and Pakhi will be accusing Virat later..if they are following the same storyline
