Bobby

I'm intrigued, would anyone classify Bobby as an antagonist? He's played by Liev Schreiber, was wrongly biased, of course, and that state of mind got an innocent kid killed, but I almost feel as if he was supposed to be the American side of Changez -yes, he is an America, and yes, he hates those people for what they did to his. But that's not all he is. He didn't mean to kill the kid, he was wrong in his belief that Changez was involved in the kidnapping but he felt bad about it, and it seemed to me that, whatever his predispositions were that he had trouble putting aside, he did like Changez just as Changez, though suspicious and frustrated, seemed at least a little bit to like Bobby.
