When Dev wanted to marry Radhika after Vishaka deserted him , he had to undergo penance by doing Kshama vrat.
Now that Radhika is around , how can he marry anyone else before doing any penance . The purohit family had to bring this information to MR. If she is planning to install kanika as RPain, Dev will have to undergo penance or else be dethroned which will spoil MR's plans .
As it is he may have to answer for staying with Kanika as his wife , even after he was reinstalled as RP . Earlier stay could be excused on the basis of his memory loss . But now he is committing adultery , which would be an anathema for his status ,
The Issue of no questions being asked about his present family situations has been raised in this forum.It is surprising that such an illustrious family & still there is so much privacy maintained , how do they achieve it ? many other celebrities might like to take a lesson from them
