Nakusha saved their LIVES, Bhao's LIFE...and they can't think past suspecting Naku of helping Supriya escape with her boyfriend? Obviously, the three shrews have their reasons...to save themselves. God forbid their big brother finds out about their roles in the Supriya affair...
I mean even if they hate her, at least acknowledge she SAVED their LIVES, so they can continue to embezzle Bhao's money (that Shifty Sudarshan), spend Bhao's money (the 3 wenches), and be queen of the house (Ayi Saheb).
I cannot wait for Bhao to be happy and not used for a change, thanks to Naku in his life. His family is a liability, and the less they are around or involved, the better (as if that'll ever happen).
