I think Yash Will meet Karan Mehta Family and Will tell about the things (MMS wala) and Asks them to withdraw the case or may be Something like that...Then Pari truth Will not reveal to anyone...Only Yash knows
Today Yash directly said that Karan Family wants to prove that he dont have any illegal relationship..So This Way Yash Will Go and Will Make Sure that His Chote ka Married life will not get into Trouble.. ...
Same Way He Reacts when He knows the truth of Prashanth wil hide it from Everyone..
