I do not think that anyone really should have something very personal against Rob, everyone knows that he is backstabbing to play, he is not backstabbing because he hates a person. At final two, Rob could very well gather votes from people, because they respect his way of playing the game, I do not think they exactly hate him as a person (like people hate Jenna and Heidi). I would think that not helping out on the camp or being outright arrogant is a much worse sin than backstabbing. Backstabbing is expected afterall. And therefore Rob might not be the best choice (for Matt ) to take with him to F2, but Jenna is.
