KD notices something about Karan, he proves that Karan was the one who killed Uttara's father-in-law. Karan had an angle against Uttara and was seeking revenge for not marrying him. He wants to destroy her marriage. Karan admits but says he knows nothing about the baby. KD again cross-questioned Uttara's mother-in-law, and made her admit that she has Uttara's baby, as she wants her grand-son but not her mother; she did this with the help of a doctor. Finally, KD solves the case & everybody reunites.
