Kripa will get trapped as the culprit behind these attacks-she has already said "mein apne bacche per Angad ka saaya bhi nahin lagana chahti". Angad also saw her on the CCTV before the pooja. Kanan will definitely like this. Kanan and Angad will get married.
She will be imprisoned for this. Angad will, therefore, get custody of Prateek
Prithvi will then come back and try to help Kripa get out of jail and convince Kripa to get back custody of both kids (poor kids).
The new promo is probably Kripa's dream and she will wake up thinking what will happen to Nishant if she said "I love you" to Angad. As always, thinking of everyone else but herself. Poor Kripa, looks like it is her turn to suffer now.
