So if this kartik is Vinayak which should logically be .. that kid got adopted and has loving parents .. who are in a proper marriage . Should virat tell him no you belong to me .. I am your father .. and Sai is your mother.. we are divorced but I have married your surrogate .
So virat will see a boy who he knows is his biological son being raised by another family ..it should not matter because he hasn’t done anything to secure Savi .. Sai will get another man in her life and he will be Savi ka real dad too
