From yesterday's episode I realized one thing for sure and that is both Anami and Laddu are the Foster kids and not even Laddu is their (Patak's) biological son. There was no way a police can arrest Patak's just because they don't send their biological son with Satrupa and she cannot pressure them on that angle. In none of PP's dialogue she said Laddu is her son and Satrupa had no claims what so ever. all she said was you can't come at your whims and take my children. Even Satrupa said panditayin's pervarish has given arrogance only and all she said is Laddu was brought up by Anami.
Further more had he been her own son, the lady who was ready to go to jail for Anami would not have bent down for Laddu. She did that only because she doesn't want him to learn that truth about him not being Their biological son.
Throughout the interaction, she was getting the flash backs of Satrupa and police inspector's dialogue about minor child has to be with their biological mother till they attain majority.
