So... today we got that clip where Sanskaar rejected Swara's love confession just like that... For whole day... I tried to made sense of it... My main guess was Sanskaar does have a bigger reason to do that. It has to be an act and now I believe it will be. Though Swara will be unaware about it.
So, as we saw today Swara told him ... whats in her heart... She also told him that samaj wale aaye thay. And Sanskaar was shocked hearing that... My theory is based on this one sentence.
Those samaj walas had literally threatened Swara saying that they will try all their tricks if she didn't leave. And about these Samaj's people; Sanskaar must know about them and their tricks because wasn't he was a victim of the bengali vs. marwari rivalry. ??
So my theory is Ragini got those signs by Swara and then created that drama showing it to everyone. It will be a totally unexpected even for both SwaSan. Since Swara didn't signed those papers willingly, she will fight it and will even plead with Sanskaar confessing her love. If you notice Ragini is also there who is adamant to throw Swara out. And now that she have sign of both of them on papers, she can once again call those samaj walas and then they both will be in a bind;also Swara will be in danger. Sanskaar can't deny that he did signed the papers. Swara can deny but that 1 crore alimony clause will create more trouble for her. And those useless Maheshwaris are not going to say anything against Ragini. So who will be in trouble ??Swara !!! And that Sanskaar will never going to let happen. The only way to save Swara at that point will be if she goes away without any other external force and that will only happen if Sanskaar refuses to accept her confession. And thats what he did.
Also, Sanskaar rejecting her at this point not only saves Swara but it also give them opening in Ragini's fortress... her mission seems to be to seperate SwaSan and if it is given to her just like that ... she will get relaxed and make some mistake and thats what is needed at this point.
