1) I agree Salman shouldn't have entered the house, not only he is breaking the rule, he may also unintentionally/intentionally let the housemate know what he doing wrong.
2) I agree that he has to really grill the contestants, but saying that, he never asks/favoring Shweta any tough questions, is wrong
Yesterday's episode he asked shweta, what u don't like in bigg boss house.
Though it may sound simple but it isn't. You know what Shweta's thinking(Dolly). But is she capable of saying it in front of Dolly who all other housemate fear and changed sides for.
3) Best mom in the world. Shweta is single mom. She was humiliated.
Dolly entered only because she would create problems for Shweta no other reason.
This shouldn't have happened.
Salman rightly gave some words of encouragement which will help Shweta in long run.
