I totally agree with your post!
The last time Sai didn't tell the family why she went out was understandable. It wasn't her story or secret to tell. It was Virat's secret and she knew that he hadn't told the rest of his family. So she didn't tell them.
But this time, even I don't see why she didn't tell them. Whatever happened between Sai and Pakhi, at least the bare minimum, the entire family knew. In fact, they were insistent that she go and bring Pakhi back. So telling them shouldn't have been a problem. I can understand that they wouldn't stop taunting her even after she tells them the truth, but now, because of her zidd, they have a chance to pick on Virat too.
Maybe she didn't tell them because she wasn't sure if Pakhi would come back. But at least, they would know that she did their bidding.
And as for Virat and Sai's silly argument, it really did show her immaturity today. And more than that, a sudden lack of trust. No matter what, Sai knows that Virat would NEVER do anything like that with anyone for that matter. Yet, she just jumped into conclusions. So, the maturity lecture was much needed today.
Dear Pakhi, you were right when you said that Sai could not understand the relationship between You and Virat because most of the viewers don't understand it either. Could you please elaborate a little other than "we are just friends" so that we actually understand the actual equation between you two? That's because the friendship you guys have is not defined in our dictionaries. Or maybe I am checking the wrong dictionaries. Please send me the name and source that I can look up to have an understanding.
^First of all, I doubt if Pakhi and Virat themselves know what their rishta is?? This "Iss Pyaar Ko Kya Naam Doon" and "Yeh Rishta Kya Kehelata Hai" between Virat and Pakhi are getting on my nerves. Sai definitely doesn't understand, and she doesn't have to. We don't want her pure definition of Friendship and Love getting stained, do we??
And yes! My favourite part of the entire episode was Virat standing up for his mom! Sai is definitely rubbing off on him. And also, it is now reality is hitting him hard on how bitter and resentful his father is towards his mother. And I'm glad that he stood up for her, and he didn't even falter. My respect for Virat's character is slowly rising, after all that I lost due to this Best Friend drama.
