Would it be possible to develop a character who's involvement in the story is zero through the story itself? To explain what I mean is by dropping subtle hints about his personality through my character's narration without having him involved or speaking. My character who's narrating says things like speak about what he thinks. For instance she's the reason 27 people died on a raid and her boss isn't very happy about this. She explains how he's not too thrilled she's a certain race and in the gov't and how he's mad he is that she's the reason '27 of his perfect Americans died' can you sense what type of her boss is without him being there?
