But till now actually sidharth hasn't once really spoken about her personal life, he has taunted and mocked regarding her actions/behaviour during tasks or particularly inside house but not personal. The way they sorted out as if they know a lot about e/o that can be used in the game.
It is possible bb is trying to create something like vikas shilpa and that's why all these are happening as per instruction but their body language says something else (comparing their interaction with others in the house)
and there is a chemistry that makes me want more of them..
