Sugni will directly confront Digvijay... Try to put logic across kuhu but will fail.If kuhu becomes pregnant, then she(Kuhu) would ask Digvijay to announce to their families about their marriage/union and take her to his home which he will not do.
She will then request Sugni to help her out. Sugni may then tell abt it to Aditya.They both may meet Jwala Thakur and his wife regarding this and ask them to take kuhu into their household.
And I feel that Vikram/ Maa thakur will be the last to know(Kuhu is scared of them).
I feel the key for Maa Thakur family to get out of this embarrasment would be Gulabia because she can influence Thakur jwala Singh. And If jwala nods then diggi and saroj would have to accept kuhu.
