When will this ghost track ends?

Hi..everyone yesterday ishraru and somebody told that ishita is going to suspect sarika. ya it came in today's precap but how come she confronted her without having enough proofs that too in single episode after all ashok knows ishitas drama. Is he trapping her or diverting her attention? Somebody told it's shaguns game plan but I still believe it is not her this time bcos shagun has also reason to take revenge from ashok as he betrayed her y will she help that cheater? She may show her true colours during surrogacy track which is next one. How come track end soon? My concern is will ishra b together after the track? do u people think raman will help her by knowing the truth before hand? One more imp thing recently heard that there is a new entry I don't know his name he is singer cum actor for small role but he was not seen yet in the show? May b is he a detective appointed by raman to know the truth about ishita what do you think guys? If anybody has source pls tell me

When all of bhallas and iyers are ready with their arrangements to welcome the great saint.

Don't know yaar..
