All you have to do to expose Rishab is

All Priyanka needs to do is record Rishab's conversation and play it in front of the family to expose him. Also keep an eye on him where he goes and what he does, record everything in the video tape and play it..
that's all she needs to do to expose him.. come on how hard it is to expose someone like Rishab.. if you know he's reality then use the latest technology..
have family stand behind certain and let him confess everything.. let family hear it.. there you go guys..

yeah so true i was thinking the same why not to use the techincal ways to expose him and which are much easier to do than collecting proofs

well its a drama u forget that i think........

if Rishab is exposed, sarey fasad ki jarah khatam, then how will they carry on the serial forward.
