I so agree with you, even if Varsha, Satish or anyone else tells him that it was Manju who made the complaint it will take time for him to forget all of it, more so bcoz
1.) He doesn't know she did it without Archu's knowledge (god knows how Archu will convince him of this)
2.) He doesn't know Archana loves him
3.) He has only seen Archana's and her family's hatred all these months, so making such a complaint is not at all unbelievable.
4.) The family may not have made the complaint, but they are still supporting Manju, not one person even scolded Manju for it... worse still they came to the Shok Sabha with Manju (does this woman even have a conscience.. she came so easily and was sitting as if she hasn't done anything at all..)
5.) No one told Manju that if you wanted to make the complaint cos of Savita, then you shud have made the complaint against her...(I guess then Manav wud have thought that maybe Savita did say ugly things and that is why Karanjkars made the complaint, cos till this incident he trusted the family plus he always gave them the benefit of doubt plus he knows his mother is a loudmouth).. but here Manju said that the entire family including Manav physically and mentally tortured Archana... (when Manav goes to Archu's house, he says exactly these words to sulochana, so its not as if they don't know what lies Manju has told in the police station) that made Manav go mad with rage which was absolutely understandable cos he had never even raised his voice at Archana.
Tomorrow, if they try to justify that they had made the complaint cos Savita had been harassing Archana, he can immediately point out that if that was the case then why did they say false stories about Manav, Vandu and the rest of the family as well... itself shows that the complaint was not an honest intention to get Savita punished.
It is not at all going to be easy for Archana to convince Manav so easily... when she goes to his house she has to show him by actions, words and thoughts that she has always loved him.. only then will Manav think that it is possible that she didn't make the complaint.. no proofs are going to work here.. its only love which will find a way...maybe he will feel a little guilty if he comes to know that Archana didn't make the complaint even though Savita had been harassing her.......
One more point to ponder on:
Manav may accept Archana tomorrow if he comes to know that she didn't make the complaint, she loves him and she has broken all ties with Manju ever since she came to know of the complaint matter... but how will he accept the rest of the family members... he will say you all knew Manju did it, her false stories itself say her intentions were not honest, you all knew how much my family had to suffer but all you did was stand in silence.. not even throw Manju out of the house...not even say sorry...this means you support her and what she did.. that they felt right to punish Manav and his family for something they didn't do... at the same time they can also say we won't send our daughter back in the house to a Monster mother in law....
I feel that the reunion will take place only at the cost of Archana breaking relations with her family... and Manav walking out of home/breaking relations with Savita.
