yes i'm agree with you that dubey was the one who did this punar vivah for aarti like a good father in law but now if he try to get back aarti in his son's life it's some how quit selfish. b/c in this point he only think about his son's happiness not aarti's neither ansh b/c both aarti and ansh accept yash bottom of their hearts, but yeah it's also natural after all dubey is prashanth's father na.
