DK will talk to purvi

I think DK will talk with purvi. after arjun explained his love tragedy. ...may be purvi will explain she is not ready to spoil ovi's and mother father happiness...again DK will present the same matter to arjun...the whole situation means purvi will know that arjun was not cheted her...according to arjun purvi sacrifice her life because of his mistake,archana,manav and ovi' sake... it's just my thought...

i think you'r right he will try to speak with purvi because he care for her son's happines but purvi will not let arjun do this and tell him to sacrfice her love.

I think DK will talk to Archana and that is how she comes to know. DK will want to take Archana into his confidence as they are both her daughters and he might be in a dilemma not knowing what to do.
