I'm actually not sure this is Amanda's real reason for enacting this strategy. I think part of what Amanda is doing here -- and I might be giving her too much credit -- is making sure she isn't treated like Becky. If she knows the show, she knows that the biggest threat when you're the Amber or the Becky or the other person who appears to be attached to someone more visually strategic than you are is that you'll look like you sat there and did nothing while they did all the dirty work. In a way, Amanda needs to make one big move that she can legitimately claim later was her idea. She's seen women like Cassandra sit at tribal council trying to argue that their play was as good as anyone's because they knew how to shut up and let the bullets not hit them, but that hasn't been an argument that's been easy to sell. The best reason for Amanda to do something unexpected at this point is really for its own sake; something strategic she can later say was her idea, so that she doesn't seem to have sit there while Todd schemed on her behalf. If people don't like James or don't want him to win, it's an even better move, because the jury will respect her for getting rid of him. Amanda interviews that she's had all the apple metaphors she wants (so apparently, James does that at camp as well as in interviews), and she's ready not to only "bite the apple," but "make the whole frickin' pie." I don't really know what that means, and I'm not sure she does either, but if she's saying she's done with Garden Of Eden comparisons, I certainly support her. So she says that if James doesn't get immunity today, she wants to send him home.
