I'm so amazed with the way Pakhi Didi's character is being played. All the emotions and flow is just so damn good. Here are few of the nuances that I noticed until now. Have a look.
1) when Pakhi Didi is happy

2) When Pakhi Didi is sad

3) When Pakhi Didi is excited

4) When Pakhi Didi is cursing her ex lover (?)

5) When Pakhi Didi is planning against Sai

6) When Pakhi Didi is not insulted

7) When Pakhi Didi is actually insulted

8) When Virat brought Sai cotton candy

9) When Pakhi Didi is not missing Samrat

10) When Pakhi Didi went home

Ah! It was so much of variety that I couldn't really pick on all of it. Feel free to add in the comments below.
PS: Fun post. Needs to be taken lightly. 😃
