Why BB protecting Shiv

When Archana questioned Shiv on why she was not granted forgiveness and allowed to stay by him, even though he himself was in the same boat as her in his BB Marathi season and was allowed to stay by his fellow contestant.

BB immediately interfered and stopped the conversation. Ever wondered why

That's because unknowingly Archana raised a question mark on BB as a BRAND. Shiv is BB Marathi winner and they allowed a supposedly violent contestants who was on the verge of getting expelled for violence to become the ultimate winner of the show.

So BB was saving his own butt not Shiv's.
