My take on the precap... Just because I saw many versions which were against Anika being a part of the Obro gang!!!!
For Rudra Anika is very special since a long time... N Om also respects Anika a lot... Be it for the person she is... Or for the things she has done for the family... Specially for his big bro!!!
N this time they have come close all cause of her... So for this time... I think she deserves to be there for the hug... M not saying everytime... But THIS time!!!
N for her being in the moment for dil bole Oberoi... I mean what more of a sweeter welcome could her brothers in law given her than the naam n khandaan(the khoon can be given by Shivay only. ... When they both will create the blood relations i.e their children) of theirs by making her relate to the brother... Who detests her for not having the same!!!
