Your second both is false. Rob did not even win the challenge where Grant was eliminated, Ashley did. In fact Ashley saved Rob's ass since Rob was an idiot to be planning on taking Grant to the F4 anyway, and Ashley saved him winning the game by winning the F5 challenge and forcing him to vote Grant out (which he should have been doing originally anyway). Had Ashley not won that challenge, Grant wins the season, so he basically needed to be saved by Ashley from his own stupidity, then loses the season to Ashley herself as well if he doesnt win the final challenge by a split second.

As for your first point yes I guess, but I am not one of those who says Russell dominated Samoa either. IMO Amber had just as much pull on the decisions as Rob anyway, in fact he usually obeyed her, and she was the one who had to live with the tribe during the tribe flip for 3 days and convince them to keep her. Who cares if the edit which was mostly done by Rob cocksuckers focus only on the Lex- Rob/Amber deal.
