kab ayenge achhe din???Somewhere in the corner of my mind I agree with your thought, BB is setting up the down fall of Shukla, making Shukla a villian , if BB genuinely wants Shukla to win, he shouldn't be overtly showing to the audience, his bias
besides, Shukla gets the wrong feedback that he is doing well and correct.
So I hope, BB is planning this suprise.
