Someone please help me understand something... The returning players were brought back for the possibility of becoming finalists, the top eight determined by a weigh in. Chris is one of those top eight. She gets to the challenge and is told "You're not medically cleared to compete...". The producers obviously knew what type of challenge it was going to be, so why was Chris allowed to take that spot? If I was the person right under her (can't remember who she beat!) I would be extremely tweaked off!
