Actually, Prats bashing is a fashion fast catching on! So now she will be bashed for what Armaan told Ellie and she was a bystander who actually comforted Ellie later. Friends, first of all, be clear, it was not Prats who uttered those controversial lines.
They were all joking and smiling, suddenly Ellie takes offence, she has every right to do so, but why expect Prats to become a crusader and take on Armaan!
And why only Prats, why no such expectations from anyone else? As it is the girl is grappling with life in Hell. She did console Ellie but being privy to everything, she also pointed out to Ellie where she went wrong and Ellie admitted she would apologise to Armaan which she also did after Armaan, rightfully apologised.
Armaan and Kamya so far are Prats',support system and she cannot confront them and fight them openly though in her own way she did try to diffuse the situation. Let us not assign a crusader and conscience-keeper role of BB to Prats. Gauhar was only instigating Ellie because she hates Armaan, not because of her love for womanhood!
This is the murky world of BB and not Satyamev Jayete (where values are upheld) so let's not try to find virtues here !
