The truth is gonna unfold in the coming episodes...
I wish it goes like...
Purvi in some urgent circumstances gets admitted to hospital in hush hush way by none other than Arjun (Without severe injury to her and baby) and therein he sud discover for himself the truth of his life ... The unasked question how cud Purvin 'move on' in her life!!!!!!!!!!!!!!
(I remember the really touchy scene when Sujal got to know in hospital that Kashish is pregnant with his child in Kahin toh Hoga)
I dont want the truth to be revealed in some Party fiasco... This time it sud be only Purvi and Arjun...
