To find the "main characters" of the season, I went with the castaways who had the top 50% of confessionals in the season. For example, let's say Eric has 20% of the confessionals, then Sally has the next most with 15%, and Rufus has 10%, and LeBron has the fourth most with 5%, that adds up to 50, meaning Eric, Sally, Rufus, and LeBron are the "main characters" of the season.
