Ratan Singh underwent true transformation in prison.
After he realised what his son could grow up into, in his company, he loved his son so much that he gave up any claims on him.Ganga and Jagya too forgave him truly, and offered him full visiting rights. But he did not want his past evil deeds to shadow his son's future...Looks like his father died in the last few years and Ratan Singh is dying from some terminal illness.His mother is widowed and taking care of her dying son. Her evil deeds too caught up with her.And all these years Ratan kept his promise. He repented. Kept himself away from Mannu when he need not have done so.Even now he would have died with a desire of meeting his son buried deep in his heart, had this chance encounter not happened.Neither he nor his mom would have gone to BH by themselves. Not because they couldn't or did not want to meet Mannu, but because Ratan was honouring a commitment to himself.He saw this chance encounter as a sign to express his heartfelt wish.Even now he is pleading and not making any claims.It is now up to Mannu's parents (as known to Mannu) what they want to do.They could refuse.They could show him Mannu's video or photo album instead.They could show him Mannu from afar.They could engineer a chance meeting but tell Ratan not to disclose anything.After all any such disclosure will only bring grief all around, especially if Ratan Singh is dying anyway.
