She was given the option to let them know or not. Why tell the others, because then they have to wonder what America may be asking them to do. I didn't understand the team thing, but I guess it's another way for them to turn on each other. If it was one person, there would be no need to tell others, but if someone else on Team America decided to tell then there would be no trust for the others. Either way, it's the most stupid twist to date and I wish they would just play it as it's meant to be and keep the outside help out of the game. If they didn't have outside help, BB would not be able to manipulate the game. Without votes, BB would not be able to manipulate the game. How do we really know how these votes turn out?
