Just listened to a little of Shambo's exit interview. Really really interesting bit--she said that at one point in the game (which wasn't shown) she was offered the opportunity to exchange places with one of the FOA tribe members. Then the handler cut her off. That might have changed everything. Have no idea whether she couldn't find somebody on FOA who was willing to swap with her, or whether it was her decision. Strange, though.
She also said that for her audition tape, she did video of her on her Harley, and of her "doing weapons demos with some of my guns."
