Does katniss warn rue that she is going to attempt to harm the careers?

Answer 1

That they're strong, but without food, they're nothing. They don't know how to get their own food, they just have a stOck of it from the cornucopia. If they blow up the food, it'll put the careers in a bad position.

Answer 2

No they do not talk about the games until they are directly in the games when they join up until rues untimely death.
