The Narrator has no power what to ever, he has to stick to the plot! If there is a Narrator, then this proves this is a story, and stories never change plots. If Orthodox dies, then he dies because the writer said so! The Narrator is a creation of the story itself, and changing it will destroy it, just like changing past/future.
This isn't Hollywood where villains just like to show they are powerful. The Narrator doesn't need to show he is not afraid, because he controls Orthodox's freaking life!
I suggest, start a war of words with it Orthodox! Use beautiful words and adjectives and try to become the Narrator. Start ordering what would happen next while staying determined, clam and confident. Think like Dickens! This will infuriate the Narrator, and he will lose control, giving you control.
After that spawn me.
