a) She's obssessed with getting her Make-up back. So? Wasn't Praneet obsessed with getting his clothes back. This is a professional actress whose on TV 24/7. It's her job to look good, her lively-hood depends on it.
b) She did not save Sushant. Again, whats the big deal. Why should she? The guy barely does any work and just became a sevak.
c) She did not save any of the nominees. Again, none of them are her friends.
For a professional actress, maybe her make-up is in fact more important than letting a friend sleep on the ground or saving people she doesn't even like. Why exactly should she worry about the good of the whole house, its not her job or her concern. She has to look out for herself. I bet each and everyone one these contestants would have chosen something personal too.
