Interestingly, Tracey is the nicest of the contestants that I have as a FB friend. She's encouraging and always responds personally to my comments. I don't see her as a "jerk." I don't necessarily agree with the moves she's made in the game, but I think she has a strategy. Personally, if I had the power to choose teams, I'd be splitting up the partners (which seems to be her strategy).
And I truly don't get all the drama about being split from your partner. They were all still there in the same gym and they were all still supporting and encouraging each other. Wouldn't it be a good strategy to have your partner on the other team? That way you could keep up with what's happening with both. Seemed to work well for Ron and Mike last season!
