I know that this must seem like an obvious question
Let me explain myself
We know that Raj takes pheras and all that with the girl he considers to be Sakshi but would he actually complete the marriage by filling her maang? Think about it. Would he even want to complete the ceremony in Preet's absence? Even if Preet stood by and witnessed it all, would he be able to do it?
I don't know the answer myself. Before the bride swap was confirmed, I was hoping against hope that Raj would just call the wedding off because he couldn't do it. I was hoping that Preet would be standing by the mandap, keeping a perfect smile on her pretty face while Raj prepared to marry Sakshi in front of her. I was hoping that by looking at Preet standing right next to him, next to the mandap where he was going to marry someone else, would make something in him just snap and stop things before he passed the point of no return. I was hoping that he would have enough humanity left in him to call the wedding off and prove that he does respect SD by not marrying her when he knows he could never make her happy. This bride swap just ruins things for me, TBH.
