Samuel asked Andrew Warren:

This question contains spoilers… (view spoiler)

Andrew Warren Thank you for your question! Yong Jin was, for me, the "face" of the MSS, who was pursuing both Caine & Sean. It was important to me that he be capable and threatening, but also not a cartoon villain. After all, he is simply following his orders and defending his country, just as any patriot would. At first, his appearance seems off putting, but I hope readers come to respect him and his relentless, yet honorable, pursuit of his duty. In a way, he may have been inspired by Tommy Lee Jone's character in The Fugitive. There were some cut scenes that focused on his investigation and pursuit more... In one scene, he reviews video footage of the prison breakout scene, and recognizes someone on the screen. I don't want to give away spoilers, but the reader was led to believe he recognized Caine... However, he actually caught a glimpse of someone else in the frame. I cut the scene, as the book was already getting longer than I planned, and it wasn't strictly nesc.
