Okay so she basically has no feelings for bihaan him being adopted but what about the elder 2 sons?? They are her own right!! So just to bring down thapki she made a laughing stock of her own sons in front of so many guests...which real mother would do tht to ensure the so called happiness of one of her sons!! It would seem tht dhruv is her only real child and she barely ever shows any form of love to any of the others...it seems just perfunctory cordial behavior but when she did something tht demeaned her sons in the eyes of others I felt tht she has failed as a mother!
