I think she is sensible, funny. But she made an error of judgement by setting foot in this house. I haven't seen the episode yet but I feel really bad for her looking at the pictures. That crying isn't fake.
Here's the deal - they are into the third week now. If she still doesn't pull herself together, then the BB team should just evict her next weekend (provided she is nominated). We all know that not all evictions are based on votes garnered. So the BB team should put her out of her misery.
BUT If she continues like this even after the talk with Salman and knowing that she got a huge support from the audience... then she would only be an expensive freeloader sitting inside who has no respect for her support base.
Either shape up or ship out. But quit being unprofessional now. It is just a house and a game.
