Mark my words...Paridhi will become pregnant...with Ayu bringing good luck to adopted parents...as soon as they come to know that it is Ayu...paridhi will not part with Ayu...this may cause a bit of tension between Arti and Paridhi but yes Prateek may support saying 'afterall Ayu is going nowhere...he is very much in the family'...so probably after much thought...she may part on one hand and on the other hand...she will find that she is pregnant !
Arti's viswas in ishwar will come out true !
