James and Brakus
James seems to know how to defeat Brakus, and indeed he is still alive at this point in the story and it is clearly established that the audience always chooses death. This begs the question. What is the story between James and Brakus?
These are possibilities in my opinion.
1. James was the previous champion and was soundly beating Brakus, until he was caught with a cheap shot. Out of respect, the audience decided to let him live. In shame, he went home and became a drunk.
2. James won the fight, and like Tommy, refused ownership of the Colosseum due to its cruel nature. Weldon, furious, at James' non-cooperation threaten the lives of his family unless he left town. Feeling guilty that he risked the lives of his family, he resorted to drinking.
3. James never actually fought Brakus, but was his trainer. Afraid to face James in the Colosseum, Brakus beat him to a pulp while he was sleeping and defenseless.
