Bill Williamson is a major character in this game and is one of the primary antagonists. Bill was once a partner in a gang with John Marston. But he is a target of John Marston in the game, due to certain reasons. This all serves as some of the games plot. It is believed that Marston and Williamson at a time were the best of friends, but obviously significant events tore them apart.
