What else could Virat ask Savi to call Pakhi? He can't say call her kaku. She is actually Savi's step mom. So he wanted his child to call his wife respectfully as badi mom and was disappointed when she rejected. Unfortunately he can't show his disappointed or scold her yet coz child is yet to enter his house. All in good time, for now Aunty is fine.
Virat or the family didn't even bother to help Pakhi or make her understand not to clean the sheet. No one actually bothered about Sai's footprints which was wierd, so everyone agreed it was by mistake only except Patralekha who put 2 and 2 together and thinks it's 22.
Ashwini Virat and Ninad are so dumb, they could have made this event inclusive for both Vinu n Savi, but they are showing blood is thicker than adoption, they didn't even think that they didn't do this for Vinu yet.
When Vinu asked the question, the way Virat nodded to Pakhi, I thought he wanted her to lie. But she decided to put him in spot that I liked. Vinu put Ashwini on spot too. Fake family showering fake love.
