BB only said what's in the contract...BB can't force anyone to stay in the house without their will! BB said I understand you are hurt about the gali, and asked Sky to think about his decision again!! I doubt that BB doesnt care!!.if BB didn't care that much he would have ignored the entire situation as he has been doing all through the season!! And BB will not take extra effort to patch up Sky and Mehek...BB has his game plan and he knows who plays games, BB pays the contestants to stay inside the house!!
When someone creates such a ruckus BB has to respond. After Sid was successful in getting PM evicted in a similar way Sky isnt one to sit and loose the opportunity. He truly thought pressurizing BB would get Shraddha evicted. And till now he sees everybody pacifying him and backing off whenever he starts his "I'm going" natak and he expected the same this time. BUt glad BB stood their ground this time and didnt give in to his silly demands over a non issue. So now he knows he can never use that card again. He did get a feeling he was indispensable to the show but he now gets the message that perhaps he is not. And so what if he goes - Im sure BB can bring in similar but more well mannered people to replace him - who may not be contestants but still can create the same hungamas --- like Dolly or Sambhavana or anyone else. Itna bhi also he is not so important.
