That seems to be the question here.
There are places where you think the show is really scripted. The first episode was the biggest clue. Sanaya 'falling asleep' before the guests arrive was completely fake and made me question just how much of this show is 'reality'.
But the comments that these people are passing are definitely not. Gizele was correct when she said "at the end of the day you are responsible for what you say and how you react." Yes seeing how this is an Indian reality show and they always need some desi masala in the episodes, I'm sure they must have told the celebs to spice things up. But whatever Ragini said to Nigar was not scripted and vice versa. Ragini picked at almost everything when Nigar hosted last night. The '1' mark she gave to Nigar was also not scripted. Same with Debina and Dimpy. There was no need for them to go in a room and bitch about Gizele in such a way. I highly doubt they were told to say such stuff. That was pathetic and really low of them, and to me, that spoke volumes about their characters.
There is a way for you to be on a reality show and not ruin your image. Sanaya Irani walked out with a clean image from a reality show. I think by far she has been the most popular celeb. of the lot so they could have used her to add their drama but she stayed out of it. Fact is, some of these contestants are plain obnoxious.
