Rehan won't be bad.....

No no please no rehan turning bad

I think rehan will realise his mom is trying to kill sanam
So he pretends to be bad and gets the twins to switch
knowing seher can handle his mom while sanam is too nice and naive

Then at the end he'll reveal to everyone that this was his plan to get his mom to reveal the truth
Plus he'll admit to falling in love with seher

And tanu spends her last days in jail
