Perhaps neither tribe or any alliance accepted/welcomed her? So if she had noone to talk to ... she didn't talk. Perhaps Cochran (meanly) called her an insult to vanilla because when the swap put her with his tribe, she didn't engage with anyone... except maybe with the most loved person ... Phillip.
I saw her web page and she is kind of cute ... and after watching Danica in the Daytona500 ... I guess I think she has an interesting and grueling profession.
Driving a race car seems to be a pretty solitary job except for the pit-crews. It's competitive, true, but not in the community sense ... so maybe she just wasn't a "fit". here.?
Thanks for you consideration of my thoughts.
