From her (and Tyson's) pre-game interview with EW's Dalton Ross:
"Hey, Tyson, are you worried about the fact that there are three contestants from Survivor: One World on this season? 'No, they're children,' answers the Tocantins and Heroes vs. Villains veteran. 'They're all children. Monica, she's 45 and tries to dress like a 30-year-old. It's ridiculous. It's not going to be hard to turn all three against each other by whispering sweet little lies, and they'll all be at each other's throats.' However several other contestants commented that they weren't sure Tyson's girlfriend Rachel would be able to tough it out in the elements. 'I think she's going to miss the creature comforts of home,' admits Tyson. 'And if you talk about that too much, you become a target.'"
