I don't know why but out of curiosity I watched today's episode after watching few clips of Virat and Savi....
Now everyone are treating Pakhi as great and head of the house and even Ashwini seems to be accepted her as Virat's wife.... I guess after Sai's return she will start losing her importance which will lead her turning negative... I.guess this is makers intention to elevate Pakhi, as they want her to have a strong reason to turn back negative...
