Neda/Heather in a final 2? I'm all for Heather, but I dont think she has a shot in hell to make it that far. She's expendable and when her alliance is left without any other options, she will be the one to go.
As for Neda, she hasn't impressed me at all. Her ketchup sabotage was annoying and childish, and she's done nothing really to stand out. If she decides to keep Sarah (which I know she wont because she's too busy sucking Jon's dick) then maybe things will turn around and she'll prove that she's actually playing the game.
Funnehliner, after Rachelle got the house punished, Neda woke up late one night and poured out all the ketchup because she was so upset, which meant nobody could make their slop better.
