But why will paro stay with rudra..

Paro can say .. I did not kill your father... I have testified against tejawat now set me free.. Let me go to my home..

Paro will want to go home, but we don't know yet if she will be accepted by the people there as she has been staying with the enemy, the BSD. Then there is the Tejawat arrest where people who are loyal to him will be angry with her. Then there are those families who have sent away their daughters in similar weddings never to be heard of again. Those people will also be hostile to her simply because she was saved and their daughters weren't.

Paro will probably be in some safe house or witness protection program during the trial period. I don't think she ll go and stay with Rudra.

Truth takes times. Eventually truth will win out but until then she should be in witness protection as was mentioned. She should be far away from that entire family including and especially Rudra. Of course this wont happen but a girl can hope 😊
