Gina's a lawyer and a very successful one apparently, so she probably is smarter, or at least better educated, than most of the others....we rarely get people with high powered jobs on this show, and not only because they are somewhat less likely to need to lose weight (there is, afterall, a social class aspect to overweight), but few are willing/able to take time off from their careers. The same reason why we have so many bartenders and pharmaceutical reps on Survivor. And on top of that most of the current contestants are 20 years younger than her. So my point is, she may not be fitting in well with the others. She seems to get along fine with Danni, so it isn't as if she can't get along with anyone. I'd like more details about how she's "poisonous" before I get down on someone who is obviously working hard and doing something right. And lizardcat, I'd also sure like to know what she's eating!
On the other hand when she gets into one of her weepy modes I want to shake her! But I do wonder if she is being edited in a negative way for some reason.
