we've been hearing for a while how after finding out the truth, angad is going to boost kripa's career at the expense of his own, how he is going to destroy his professional life and enhance hers.
the way i see it, in a way, it is killing 2 birds with one stone. on one hand, this could be his way of "praschit" (not that professional success would matter that much to kripa after losing her self esteem, self-respect, her love and most importantly, her baby at the hands of the man she lived to love). and on the other, destroying his career would be the worst "saza" that he could give his godzilla mother. no matter how fiery angad might be or how manipulating naina could be - angad would never harm his mother in any way. but he knows (we all know) how important his career is for naina. his jeopardizing that same career would be the worst blow to her.
my opinion - serves her right!!
