So I had an idea for a story. I haven't completely thought it through yet but essentially what happens is a foreign celebrity comes to America and clashes with the protagonist of the story in some way. It doesn't really matter how... the point is that they are going to have to speak to each other and be able to understand one another while both of them speak different languages. Do you just make up a character that can be the person's translator and do it that way? Or do you cheat a little and come up with a reason for the guy to know English?
