Okay... well, it depends... if he is young, I'd call him Santiago (James), he'd live in Tigre, in Buenos Aires and he would study something that could be useful in your story. I don't know if `"politics" or law-stuff, but i guess he should be smart and a fast-think-er, to at least apport something, like strategies... in Argentina, we have this habit of thinking and re-thinking stuff (even when it isn't necessary) and bringing things back to mind and learning from the mistakes we've done before... you know.
I promise I'll start reading, the USA-splitted thing just got me thrilled!!!
