Once Sid comes to know the truth, Roli should not forgive him easily.
If she is there, it is difficult for her to ignore Sid.
She should disappear for a while and Sid should pine for her.
But it will not happen. Sid will be forgiven in a jiffy and I think she has already forgiven him.
I remember how Prem did not forgive Simar easily and made her suffer for a long time for faking her death.
