In the mean time she can also find out about her past and connection with Seher and THEN she can help to release Seher out of Jail
This would be Seher's redemption track (lets be honest here...Asya's daughter or not, Seher needs redemption for what she is doing to Sanam right now if not for other things she has done so far...actually IMO for the others too) and would give Sanam the focus she deserves in handling Tanveer about the property signing issue and navab murder truth.
Once Seher is brought in all the sisters (including Haya) can find out about their parents murder and the final exposure of Tanveer.
