Remember what BB was actually about. Despite it being a comedy, BB has an important message behind it. Bhakar didn't respect women and would play around with them not caring for their feelings so he gets turned into Bharti. Since then she has experienced what every girl goes through. BB is carrying the message of how hard it is for a girl to survive, how unfair it is for women in different parts of the world.
Since this has been mostly a comedy show we have forget that this show is trying to also display a social message. Women DO get raped by their husbands, and like Radha, women are treated unfairly. And now Bharti is going through all the things that happen to women so she will understand their pain.
So with this rape situation, I don't find anything disquisting or horrible about it. This is a fact and we have to remember it. We should be proud that BB is brining up this issue rather than be disguisted by BB ..
But it also IS a drama so of course we will have Armaan save her!
