It's often frustrating when you're a war reporter and you're covering these places that far away. You're frustrated by making stories that people can't connect to in any way. It's hard for Americans to connect to Arabic-speaking Iraqis in refugee camps or Pashto-speaking Afghans in the countryside, and having a character who is a vehicle through which you're allowed to make these relationships really allowed us to gain in an emotional weight that was difficult for us to do any other way to make it all human.
