Raj suspects her, like he is 99% sure it is her but beeji is clueless as of now as Sid denied Simran pressurizing him.
She is just getting an easy way out after doing TERRIBLE INHUMAN things to the Patel house. I really hope that the CVs make her pay for her selfish and unjustified deeds. I have always said that DD is a lot better than Simran since DD has good reasons for her arrogant behavior but Simran's behavior is just un-explainable
