Since there is no hope of Arvi marriage... this is possible.
Archana is not Purvis biological mother
Archana is neither Sacins biological mother
Therefore there is not any kind of blood relation.
Purvi and sachin calls manv "baba" but not even he is either one of thems biological father.
Sachin doesnt accept Archana as his mother and since there s no blood relation between them whatsoever I dont see any wrong in this. And After tonights episode Iam really mad at CVs and Ekta for seperating ARvi. I mean what do the think marrige is? a game that Arjun and Ov can play for a while to make Purvi and Archana happy... disgusting. Anyways what is done s done and frankly I dont mind at all seeing Purvi and Sachin. as you said Sachin might have seen another side of Purvi now and she will definilyley try to come over arjun now hat he is married to her half sister. and might become friends with Sachin,,,
Anyways... Iam sooo mad at cvs for doing this... marrige is not a joke... engagement part was okay but seriously marriage... arghhh
