What she actually does is a criminal profiling so she probably does more office work, she doesn't go out on patrol. Going up to the HOH didn't bother me, they all do that and I think BB wants them to go have talks with the HOH for filming. I've heard them say as much, not so much this year but other years. (This group talks about their DR's all the time and also about production, even when they are getting the BB warnings.)
About casting, every year there is a HG like her. Jerry, Renee, Sharon, Sheila, Keesha come to mind. They are expendable, sad to say.
It's academic now isn't it. She's going to join Rachel tomorrow in the JH.
