over and over she kept reminding herself, looking at Kripa's pictures hidden in angad's closets, she saw the looks between them when both are in the same room, and all the incidents that took place, after angad had already told her that HE LOVES KRIPA AND PRATEEK IS HIS SON i just can't comprehend how she would still have it in her to be this type of person. on the other hand there's nishant who once he found out he just couldn't be that selfish to ruin a family and decided to bring them together. Can't she see that they need to be together and their love won't go away. When she saw Kripa at the door yesterday she should have talked to her and tried to make Dadi understand.
and as for Dadi since when is Kanan your blue eyed girl and Kripa the girl who gave angad so much dhoka, aside from witnessing against him you were the one who always told him (and her) that your love is so strong that it will see through all misunderstandings. what a two faced woman.
