One of the challenges in writing a novel is what to do with all the secondary and tertiary characters in the book as the plot comes to its conclusion. What happens to the main characters, well, happens. Yes is it's a bit contrived because as the writer, I have bird’s eye view and can tweak and adjust events to drive the plot.
Situations drive a character’s actions and emotions. For the main characters, what happens to them at the end of the book is plausible based on the story.
What I’ve found in other books as well as in The Assassin was that I have a few as in two or three minor characters and I have to decide whether or not I should leave the reader (and the character) in some sort of limbo, or write a passage that provides closure. Its like wrapping up loose ends.
In The Assassin there were really two that I had to figure out what to do with. As I neared the end, nothing popped into my brain as what was right (write?) for the character. In fact, in the last chapter, I literally had placeholders with the scene dates and the characters name and a row of question marks. I had no idea what I was going to do with these two men.
So what I did was wait until I finished the book and then came up with some ideas. It required going back and adding a scene or two and in fact, several scenes so that in the last scene in which the individual appears in the novel makes sense.
For the other one, I struggled. Do I leave him in limbo? Or, do I let him get away with what he’d done? Or, do I make him pay the price and if so, how? Yup, I had to pick one and in the end, I did. You’ll have to read The Assassin to find out what I did.
