This is something I wrote is another thread. Although it is not strictly pertaining to yesterday's episode it discusses the ramifications of what they showed yesterday.
What would Sultan gain by racking up the past which is clearly disturbing even to Meera?
She is pining for her son and not for her wayward husband. If he had kept her with him and allowed her to slowly become attached to his family, she could have recovered fully and be the loving mother to him and grandmother to his son. Aryan would have got the much needed female influence in his life. Sultan's motives, however, are not so noble. Although he keeps saying he wants justice for his mother and her identity back, he has gone about it in the wrong way. What was he hoping to achieve by forcefully making them stay in RK Mansion? He does not want her to know it is MK's house. He is apprehensive that she will see his picture or hear his name. So in effect he knows that she hates the man and does not want to do anything with him. So why thrust him on her and her on RK and the rest of the family?
As to getting back her identity, how was he planning to do that? And what is her identity? Wife of a scoundrel who is not alive anymore to accord the status of a wife in front of all? Isn't it more humiliating to have anything to do with a two timer? I think when MK ditched Meera, she could have sullied his image in public because he was a big producer but she did not because she wanted to lead a life with her son. It is only after that son was taken from her that she went mad. Note that she did not go mad after MK ditched her. Motherhood was more important to her than being the wife of someone as unworthy as MK. By helping to restore that motherhood and now grandmotherhood, Sultan could have got back her identity. Instead Sultan has spoilt for a fight with the man to whom he lost the woman he loves. So is his motive really sacred? I think not.
A gangster who was leading an undercover life till recently suddenly wants to be in the eye of the public by barging into a superstar's house and forcefully living there. If tomorrow his rival gang members kill him, would Meera not lose her son and his son not lose his father. Would that not have a very bad effect on the mother for whom he is fighting now?
So revealing the truth achieves nothing but pain for Sultan's family.
It has already hurt RK's family and Radha is an emotional mess. The poor woman held her tongue and refused to bad mouth her late husband to her son even when he shunned and humiliated her so badly for moving on with another man after her husband's death. She could have easily justified her remarriage, saying that if his father could have married again when the first wife was still alive and even beget a child why could she not do so after her husband's death? She did not do so because she cared for her son and knew how much he respected and loved his father. She tried to keep his memory of him intact and took the flake for it for 16 years. If Madhu had not come along and changed RK's mind, he would have continued to shun her for the rest of his life and she was even prepared to face that.
If the truth reaches RK, he will be shattered. He may be an adult with a high IQ but his emotional quotient is pretty low. He has just begun to realize the strength of relationship and is beginning to exhibit his emotions freely without fearing he will lose it all. If he comes to know that the one man whom he had held in high regard during all his dark years when he was struggling to come to terms with the realities of his life, he will definitely go into deep depression. What is worse is that not only will he have to digest his father's sins but he will have to digest the fact that Sultan, the man he hates the most, is his half brother. I think that will hurt him more. If he breaks down, Madhu will shatter too. Now does Sultan who claims to be Madhu's friend want to see her in that state? What sort of a friend is he?
In sum, by thrusting himself into their lives, Sultan has shown he is neither a good son, a good father or even a good friend.
