it he care for her so much, why he didn't question her before about it.. now after ragini's marriage to that family, so much care for sadhana came all of a sudden..!! i wounder whether it is real, or it is related to his love for ragini.. other aspect is he is a writer so he is interested to know about aalekh's background..
mamaji always used to care for sadhna and mamaji's love for ragini and sadhna is equal...no partiality is there...its only because he saw this avtaar of aalekh for the first time which made him go and aks sadi about aalekh condition!!! he obviously wants to see aalekh's condition to become normal so that sadi also lives happily!!!
